    SUMMARY
	The authors consider the nature of underlying truths that may apply to 
	surveyors and all spatial scientists, regardless of their field of endeavor 
	or employment circumstances. Drawing on and expanding previous work, a set 
	of practice principles is proposed in three themes: Application (of the 
	sciences), Behaviour (conduct) and Context (business or research 
	environment). The authors have taken the work forward to the 
	professions,particularly young professionals, with encouraging results. 
	Methods of sharing and propagating the work are discussed. In light of these 
	experiences, it would be appropriate to rename ‘Principles’ as ‘Questions’ 
	as questions invariably lead participants from the abstract to the tangible 
	by way of story-telling. Story-telling, the most ancient form of 
	communicating, sharing knowledge and understanding, has its place in modern 
	professional development.
	1. INTRODUCTION 
	In previous work (Byrne and Kelly 2005) the scope, identity and 
	composition of the Spatial Sciences was examined. The primary theme of that 
	paper was that the various branches of surveying and the spatial sciences 
	are bound by a common set of principles. A set of proposed principles was 
	published as ‘The ABC of x,y,z’. 
	The authors were encouraged by the reception given to their work, 
	particularly from young professionals. The experiences gained from workshops 
	and other presentations since the original work have provided useful 
	insights in to how the concept of principle-based-practice might be 
	encouraged in future. 
	The aim of this paper is to share the original work and recent 
	experiences in Australia with an international audience, recognising that 
	any take up-or adaptation will require modification to reflect national, 
	institutional or cultural differences from those from in which the work was 
	born. 
	2. THE ‘WHO’, ‘HOW’ and ‘WHY’
	2.1 The ‘Who’ 
	This work has been focused on practitioners of the ‘spatial sciences’ – 
	those who undertake the first nine functions of the eleven defined by FIG as 
	being those of a surveyor. (FIG 2004) The Spatial Sciences are performed, 
	managed and taught by large and small local, national and international 
	corporations, government agencies at all levels, individuals and 
	partnerships; and by teaching and research institutions. The work is done by 
	qualified scientists, administrators, teachers, researchers, technicians 
	and, in some circumstances, people with low-level skills and education. 
	The roots of modern surveying and spatial sciences lies in the great 
	explorations , navigations and mapping expeditions of the 18th and 19th 
	centuries. When we consider how the basic principles of the spatial sciences 
	may have been shared and passed on in previous times, it is not too 
	outrageous to suggest that it happened around the campfire, in the mess or 
	at the office, or in the course of the work which was more likely done less 
	frenetically and with less distraction than today. 
	2.2 The ‘How’ 
	The changes in surveying and the spatial sciences are most easily 
	demonstrable through the changes in the technologies. The technology shifts 
	have brought with them the separate IT strand of the spatial sciences – 
	Geoinformatics and GIS. The result of these developments has been in higher 
	quality and faster delivery. Spatial information has never been more 
	affordable. More is being made, sold, and used. 
	Two shifts in the technology continuum are particularly pertinent to this 
	discussion. The first is in the tools becoming less transparent, less 
	tactile, as analogue has given way to digital. Modern professionals or 
	technicians rely on equipment that contain algorithms and sensors to which 
	they have no direct access. The second shift is in many of the tools being 
	available to others without the foundation in the sciences. GPS is an 
	example of an ‘everyman’s’ tool. 
	In the space of one professional lifetime, education of surveyors and 
	spatial scientists has become almost exclusively the responsibility of 
	universities and technical colleges. Curricula are defined in discrete 
	learning ‘units’ that can not be practicably connected with any 
	philosophical glue. 
	2.3 The ‘Why’ 
	It is an interesting phenomenon in the spatial sciences that we rarely 
	define ourselves in terms of the ‘why’. Definitions are typically by 
	function. FIG (FIG 2004) defines the surveyor by function alone. 
	Hydrographic surveying, for example, is not commonly defined as: providing 
	the information and infrastructure upon which the safety of ships and 
	mariners depends. Cadastral surveying is not defined as: providing the 
	framework which underpins the human settlement process and upon which the 
	financial security of many citizens depends. When the ‘why’ is considered, 
	the consequences and costs of our mistakes and shortfalls become apparent.
	
	2.4 Questions Arising From The ‘Whom’, ‘How’ and ‘Why’
	 
	
		- Given the importance of our work or, more importantly, the potential 
		cost of our failure, what are the fundamentals, the tenets, the 
		principles, that we need to observe to ensure success for ourselves and 
		satisfaction of the needs of others?
- How can principles be passed from the experienced to the less 
		experienced?
3. STANDARDS, SPECIFICATIONS, PROCESSES
	To understand the concept of Principle, it is useful to look first at 
	other parameters that are familiar in applications of the Spatial Sciences.
	
	Standards attempt to regulate behaviours and products, defining limits 
	within which behaviours or products will conform. Almost every product can 
	be compared to a standard. 
	Specifications and Standards are similar. Specifications may be 
	‘process-oriented’ or ‘outcome-oriented’, or a mix of both. Specifications 
	provide a statement of buyers’ expectations. Specifications may refer to 
	standards. 
	Processes define the steps to be taken. They should be designed by people 
	who understand the technologies and the end requirements. Processes are 
	changed as improvements are realised or technologies change. Good processes 
	are based on underlying principles. 
	
	4. PRINCIPLES
	
	Technological change persists. The transmission of knowledge has moved 
	from workplace to classroom. Government-financed training has lessened. 
	Employees are less likely to enjoy long term working and learning 
	relationships within corporations. Technologies tend to opacity and frequent 
	change. Competition is unlikely to lessen. These trends put pressure on 
	organisations and individuals as they strive to succeed. They provide more 
	reason than ever to revisit and to consider fundamental Principles. 
	Principles, tenets or fundamentals? The words are interchangeable. We 
	chose ‘Principle’ because of its familiarity, disregarding its many other 
	meanings and applications. For the purpose of our work we take ‘Principle’ 
	to mean:
	
		- a rule or standard of action or behaviour
- a basic truth, law or assumption; or
- a doctrine or tenet.
4.1 Another View of Principles
	As these thoughts emerge, Principles start to be seen as laws we should 
	always consider. Another way of understanding Principles is to imagine being 
	involved in litigation, in the witness box, answering questions from a well 
	prepared barrister: 
	“We have already established that you are an experienced and respected 
	surveyor. We have also established that my client’s reliance on the 
	information you provided has cost him considerably. You have demonstrated 
	that you have followed established processes in your work. So, tell me, what 
	fundamental, what tenet, what principle of your profession and your science 
	did you overlook to bring you to this unhappy place today?”
	4.2 The ABC Themes
	Principles may be grouped to address the issues of the ‘how’, ‘who’ and 
	‘why’ in three themes: 
	
		Application - the ‘how’ of the science and technology
		Behaviour / Conduct – the ‘who’, relationships with stakeholders 
		- client, community, employer, colleagues
		Context – the ‘why’, the business ‘how’, communication with 
		client and user. 
	
	A set of proposed principles based in these themes is summarised below 
	and then expanded in the following sections. 
	
		
			| Application | Behaviour(Spatial Sciences Institute 2003)
 | Context | 
		
			| 1 | First, 
			consider the whole | 1 | 1st 
			responsibility is to the community | 1 | Confirm 
			the client and interested others | 
		
			| 2 | Know the 
			tools | 2 | Act well 
			and with honesty | 2 | Define 
			the objective | 
		
			| 3 | Consider 
			contributing errors | 3 | Stay 
			within competence | 3 | Be aware 
			of external constraints and expectations | 
		
			| 4 | Record 
			defining parameters | 4 | Develop 
			and maintain knowledge and skills | 4 | Assess 
			and share the risks | 
		
			| 5 | Beware 
			the bounds of convention | 5 | Act in 
			the interests of client or employer | 5 | Define 
			the critical terms | 
		
			| 6 | Build 
			proof into the process | 6 | Inform 
			clients and employers | 6 | Test 
			processes against project scope | 
		
			| 7 | Engage 
			the user | 7 | Reveal 
			conflict of interest | 7 | Attribute 
			contributions by others | 
	
	6. PRINCIPLES of APPLICATION
	The Principles of Application accommodate the laws, theories and rules of 
	the underlying sciences. While the sciences remain unchanged so, too, will 
	the principles, regardless of changes in technology. Principles are 
	proposed:
	5.1 First, Consider The Whole
	This principle may be stated in other ways: Work From the Whole to the 
	Part, Start With the End in Mind. Considerations of scale, congruence and 
	design demand observance this principle. 
	‘Working from the whole to the part” is a well recognised surveying 
	principle – working within the control system, extrapolating from the 
	longest baseline. Interpolation contains errors, extrapolation grows them. 
	The principle seems self-evident. Yet, it is not always easy to apply. 
	Modern measuring technologies are such that the ‘whole’ – the control system 
	- may be found deficient. The assembled parts may be more accurate than the 
	‘whole’. This may require the surveyor to consider changing the ‘whole’ to 
	fit the ‘parts’, raising questions of other data which are related to the 
	‘whole’, and other users who rely on the data. Resolving issues arising from 
	non-congruence of the parts and the whole demands wise professional 
	judgment. 
	Considering the part-within-the-whole is essential for the maker of any 
	set of spatially related information. Design wisely precedes creation. 
	Without a clear vision of the ‘end’, the exercise will be compromised. 
	Remote sensing specialists and GIS developers consider “part’ and ‘whole’ 
	when assessing the scope and scalability requirements of the project or 
	phase. Scalability impacts infrastructure requirements such as computational 
	intensity, data storage capacity, data administration and network 
	requirements. Professional judgment based on experience will indicate an 
	optimal solution given the client’s vision, budget and risk aversion. The 
	practitioner reflects on the part (current project specific requirements) 
	and the whole (parallel complementary or future projects). 
	5.2 Know The Tools
	This principle is more important than ever before. Within half of a 
	lifetime, the tools of our professions have become opaque, automatic, 
	capable of high rates of production. Modern tools are subject to improvement 
	and change on a regular basis. New versions appear. Surprises lurk. Maker’s 
	claims require validation. The tools must be capable of delivering the 
	results required. 
	The imperative to ‘know’ the tool on which one relies can be understood 
	when imagining the earlier barrister’s question. It would be wise for the 
	professional to not rely only on a manufacturer’s claim without ascertaining 
	that the tool performs as expected, and is calibrated. 
	As the tools become more opaque, their workings not so well known, the 
	necessity for empirical methods of testing and calibrating increase.
	5.3 Consider and Analyse Contributing Errors
	In most applications there will be an expected accuracy of object in 
	space. Errors come from a number of sources. Errors need to be assessed and 
	analysed as part of the design process. 
	Photogrammetrists assess and propagate the contributing errors of ground 
	control, aerial GPS control, aerial triangulation, camera and capture to 
	design their processes to achieve objective accuracy. Remote sensing 
	scientists consider raw or pre-processed data from various sensors with 
	varying resolutions in analysing land change phenomena. GIS implementers, in 
	integrating data of variable thematic and spatial standards, consider the 
	resultant reliability to be expected by the user of the merged information.
	
	Experienced professionals may do this instinctively. There are traps . 
	The processes and technologies that contribute errors are ever in change. 
	Some new technologies improve accuracy or precision, others worsen them. It 
	is sensible to consider each error separately. 
	In a competitive, litigious and time - sensitive world, surveyors and 
	spatial scientists will heed this principle to ensure that their process 
	designs are not so robust as to well exceed the target, be price - 
	uncompetitive or delivered late; or, more importantly, that they do not fail 
	to achieve the required accuracy.
	5.4 Record the Defining Parameters 
	Today’s spatial data becomes tomorrow’s evidence of change. Spatial 
	Reference Systems are amended, corrected and changed. In Australia we are 
	fortunate to have a spatial reference system of the high quality. Yet, 
	lurking in it are residual mistakes and deficiencies. Many other countries 
	are not so fortunate, having reference systems in transition, or even decay. 
	Some countries have crustal movement that defies the notion of a stable 
	reference system. Attributing a spatial data set with only the name of map 
	grid and geodetic datum is inadequate if this principle is to be honoured. 
	Reference to specific monuments and their ordinate values can overcome this 
	deficiency. Hydrographic surveyors’ descriptions and recordings of Chart 
	Datum parameters provide a good example for honouring this principle. 
	Environmental projects of state and national significance are 
	establishing baseline data sets for current and future analyses. Due to the 
	magnitude of these projects, future users working at the local scale need to 
	confirm the integrity of the data for their scale of project, as the 
	surveyor checks the origin of his coordinates. The range of defining 
	parameters - spatial, spectral, temporal - is a reflection of the diversity 
	of the work of surveyors and spatial scientists. 
	Adherence to this principle is supported by the increasing use of 
	metadata with sets of spatial information. More of our work consists of 
	adding to or building on existing data, making this principle more pertinent 
	as this trend continues. 
	5.5 Beware The Bounds of Convention 
	This principle may otherwise be stated: “avoid foisting the 
	unconventional on the client or the user”; or “beware of letting your 
	innovation become another’s confusion”. It reminds the practitioner to 
	remain aware of convention. 
	This principle covers almost all parts of the spatial scientist’s 
	professional life. It can be applied to records, physical monuments, 
	drawings, maps, reports. It may be better understood by considering some of 
	the conventions we take for granted. This principle gives a reminder that 
	surveyors have clients from many industries and communities, each with its 
	own language, jargon and conventions. A mine surveyor would be ill advised 
	to change the thirty year – established vertical reference datum of a mine 
	to the national datum without good reason and careful consultation. 
	This principle is probably most important in the field of 
	geo-visualisation or cartography and the employment of symbolisation. 
	Consider a fanciful revision of the symbols for the channel markers on a 
	hydrographic chart! Having said this, strengthened or improved conventions 
	would not evolve without critical review and continual improvement. 
	5.6 Build Proof Into The Process 
	Users expect reliability and accuracy. Understanding this, surveyors make 
	provisions to ensure expected levels of reliability and accuracy are 
	achieved. 
	Proof of achievement comes from the external check. Redundant 
	measurements built in to the process provide confidence in the process and a 
	measure of proof. Repetition does not constitute proof. The external check 
	stands alone because it can reveal failure to detect some hitherto 
	overlooked blunder or systematic fault. 
	The remote sensing scientist producing land clearing maps for court 
	should incorporate both spatial and attribute redundancy. Surveyors 
	routinely ‘close’ between control and compare new measurements with adjacent 
	or previous surveys, so providing the external check.
	Many organisations now use third party independent checks of mapping. There 
	is no proof without the external check. Consider again the probing, 
	well-briefed, barrister! 
	5.7 Engage The User 
	This principle is based on the notion that all of the foregoing is 
	relevant only if the outcome is understood by the user. 
	Modern methods of creating data move toward virtual reality. High 
	resolution terrestrial and aerial sensors give the potential for virtual 3D 
	worlds. Yet the existing paradigm for geo-visualisation is grounded in the 
	assumption that abstraction is needed for achieving insight (ICACI 2003). 
	There is tension between the data (the truth) and the designer of the 
	information. This is recognised in The Principles of Cartographic Design 
	(Cartographic Society 2002) some of which are drawn on here:- 
	How is the user engaged? If not by a virtual world, engagement will be 
	enhanced by:
	
		- Hierarchy With Harmony - important things should look important and 
		the most important should look most important
- Simplicity From Sacrifice, Clutter to Clarity – as in music, the 
		spaces are as important as the notes. Clarity, and so engagement, can be 
		achieved by leaving out that which may be left out without compromising 
		the themes to be transmitted, by the use of symbol and generalisation 
		without altering the effective truth.
Fra Mauro, a Renaissance cartographer to the Court of Venice, imagined in 
	‘The Mapmaker’s Dream’ (Cowan 1997) reflects on the purpose of his craft as 
	a Cartographer: the craftsman’s task is to extract a form from what has been 
	given to him, and to make of it something that appeals to the heart as to 
	the mind. 
	Engagement of the user goes beyond spatial information to the language of 
	the user. Scientific jargon, unexplained acronyms and legal terms may 
	baffle. Metadata (5.4) are unlikely to provide engagement with a user other 
	than another professional. Two codes are needed – our technical language for 
	our colleagues and peers, and the common language of the user. 
	Of all the Application Principles, this one relies most on professional 
	judgment and experience, even intuition, and a sound foundation of 
	knowledge.
	6. PRINCIPLES of BEHAVIOUR 
	Professional societies have Codes of Ethics. Most share a common base of 
	the values of competence, truth and social justice. The following section is 
	drawn from the Code of Ethics of the Australian Spatial Sciences Institute 
	(Spatial Sciences Institute 2003). The separate sections reflect tenets of 
	the code. Ethical dilemmas occur when one tenet of the Code can not be 
	honoured without apparent breach of another. In a professional life, ethical 
	dilemmas will inevitably surface. 
	6.1 First Responsibility Is To The Community 
	The welfare and rights of the community come before professional, 
	personal or sectional interests. The community includes employees, 
	colleagues, all other people. The tenet reminds us that the professional 
	needs to be aware of the wider consequences of actions and advice. Sometimes 
	the objectives of a client and community interests may be different, 
	creating a dilemma. 
	6.2 Act Well and With Honesty 
	This tenet hardly needs explanation. A professional is not expected to 
	receive payment from more than one source for the same service, unless 
	revealed. Under this tenet, a professional would be expected to not damage 
	the reputation of others, or seek to supplant another already engaged by a 
	client. 
	6.3 Stay Within Competence 
	This tenet would seem self-evident. However there are occasions when the 
	assignment requires the professional to try new methods or develop new 
	processes. Principle 7.4 requires informing clients of risk. In a 
	technology-based profession, it is easy to imagine this Principle leading to 
	a dilemma. 
	6.4 Develop and Maintain Knowledge and Skills 
	Any professional is expected to stay up-to-date and adequately skilled; 
	and to encourage staff to do the same. Most professional societies have 
	measurable CPD programs intended to keep members informed and competent. 
	6.5 Act In The Interests of Client or Employer 
	The professional is expected to take an active interest in the interests 
	of the client or employer. It is only when these interests clash with other 
	principles that dilemmas arise. This tenet reminds us that every 
	professional, regardless of employment circumstances, has a client. 
	Identification of the client is considered in 7.1. Confidentiality of 
	employer or client information is expected. 
	6.6 Inform Clients and Employers 
	The professional not only looks out for the interest of the client or 
	employer, but also informs the client about risks, potential difficulties, 
	matters that may impact on interests - issues of environment, regulation, 
	law or relationship. 
	6.7 Reveal Conflict of Interest 
	The professional is careful to reveal any conflict of interest – real or 
	apprehended. Any external relationship which may be seen to compromise the 
	impartiality or objectivity of a professional is best disclosed at the 
	start, or as soon as it becomes evident. A common saying is: ”if conflict of 
	interest is questioned, it probably exists”. 
	7. PRINCIPLES of CONTEXT 
	The Principles of Context guide surveyors in their communications and 
	immediate relationships in carrying out their work. The Principles of 
	Context and Conduct will be found to overlap. They may be expected to change 
	as society and relationships between its sectors change. Principles are 
	proposed:- 
	7.1 Confirm The Client and Interested Others 
	There is always a client, regardless of one’s employment status. If we 
	consider that the Client is the one to be satisfied by our actions or our 
	product, it will become apparent that identification of the client is not 
	always as simple as may at first appear. The client is not necessarily the 
	one who pays. There may be a multiple client, or common clients. They may 
	have different objectives. There may be other interested parties. Cadastral 
	surveyors are familiar with the need to take into account the rights and 
	needs of adjacent title holders. 
	So the question “who is the client?’ followed by “are there other 
	interested parties?” will allow this principle to be honoured. 
	7.2 Define The Objective 
	As with the preceding principle, this one is seemingly simple, yet 
	deceptively difficult to practice. The Objective may be better termed the 
	‘Business Objective’. It is the answer to the “why” question. Asking the 
	“why” question is, by itself, a skill that does not arrive without practice. 
	Determining the objective is an essential skill of a practitioner. If the 
	objective is defined and satisfied, other complaints, criticisms and 
	perceived shortfalls will fall away. 
	It is one thing to define an objective and another to know it has been 
	achieved. Agreeing at the start how the outcome will be judged is wise. If 
	the objective is subjected to a reality check, ambiguity of conformance at 
	the completion of the project will be greatly diminished. It is sensible to 
	document the Objective, the scope, deliverables and timing and have the 
	client sign off before proceeding. 
	The ability to define the objective with the client is arguably the skill 
	that will best foster sound business relationships. 
	7.3 Be Aware of External Constraints and Expectations 
	This principle may fall in to the category of “it goes without saying”. 
	We include it nonetheless. 
	There are branches of the Spatial Sciences community that already work 
	within the constraints of external authorities. Cadastral surveyors work 
	within planning and land registration laws, regulations, guidelines and 
	codes. Engineering surveyors are aware of engineering design standards. 
	Mining surveyors are bound by regulations that are principally safety– 
	related. Hydrographic surveyors understand that their work will be 
	scrutinized by a higher authority and relied on by many. The spatial 
	scientist rarely does work without being in the shadow of some external 
	authority. These shadows can be legal, financial, political, technical or 
	ethical. Some are implied in other parts of this work 
	In contrast to the work of the various surveying branches mentioned here, 
	a GIS developer, remote sensing scientist or cartographer does not require 
	license or accreditation to operate. 
	Remote Sensing specialists working on a statewide, baseline vegetation 
	mapping project operate in the shadow of current ‘technical best practice’ 
	in preprocessing, analysis and accuracy assessment. There are no statutes or 
	guidelines or requirements to lodge this information in connection with land 
	title. (This may change in future when biota rights become more well defined 
	and concern for the environment escalates. ) 
	It is not difficult to imagine a time when the work of spatial scientists 
	other than surveyors will be more regulated, more subject to external 
	constraint. The practitioner would be wise to remain aware of the 
	ever-present external constraint of ‘reasonable standards of practice’. 
	7.4 Assess and Share The Risks 
	There is always risk of failing to meet technical or time requirements; 
	of finding unknown circumstances in a greenfield site; of atmospheric or 
	physical conditions frustrating the mission. There may be a risk of not 
	being able to find all the underground services. Access to the site may not 
	be granted, or the planning authority may refuse the application. 
	If the risks are identified at the start there will be less likelihood of 
	dissatisfaction or dispute when the possible becomes reality. There are 
	times in professional life when “I told you so” has to be said, preferably 
	not in those words. 
	7.5 Define The Critical Terms 
	This principle might otherwise be called “agree on a common technical 
	language”. While others of the contextual fundaments apply equally well to 
	many other disciplines and industries, this one is nearer to being exclusive 
	to the spatial sciences. 
	There is a word in our lexicon that is particularly problematical - 
	“accuracy”. By itself it has little other meaning than ‘nearness to the 
	truth’. It has no specific meaning in error discourse. Yet it has been and 
	still is used to define the spatial quality of our work. It might variously 
	be interpreted as Standard Error or RMS, or as ‘the error unlikely to be 
	exceeded’, or ‘tolerance’. A factor of three separates the extremes. Finding 
	and adopting common definitions of error which have less chance of ending in 
	client dissatisfaction have been discussed (Jonas and Byrne 2003). 
	Until industry expressions of error are standardised, and even well 
	after, this principle remains one to be kept in mind always. 
	7.6 Test Processes Against Project Scope 
	Having defined the objectives, the scope and the processes to achieve 
	them; and having shared the excitement of being awarded the contract; the 
	work starts. On projects that last over long periods it is not unusual for 
	objective and scope to be reconsidered and adjusted. If the spatial 
	professional does not consider the chosen processes against the new scope or 
	timeline, there is a possibility of not delivering to specification, on time 
	or to budget. The effects of incremental scope change must be considered and 
	compensated. This principle might be re-named “Beware of Scope Creep”. 
	7.7 Attribute Contributions By Others 
	Easily overlooked and likely to become more common as data sets are more 
	available and accessible, it is important to attribute the authorship or 
	provenance of all data used. This is not only demonstrates good manners and 
	respect for others, it may avoid embarrassment, or even claims for damages, 
	should data from other sources be found deficient. 
	8. PRESENTING AND EXTENDING THE WORK 
	The first public presentation of ‘The ABC of x,y,z’ (Byrne and Kelly 
	2005) generated an encouraging level of enthusiasm among younger 
	professionals. (The emergence of ‘Young Spatial Professionals’ as an 
	energetic and influential part of the surveying and spatial sciences 
	community in Australia is a noteworthy story of its own). Consequently, 
	workshops and presentations were undertaken in four Australian states in the 
	following year. 
	The first lesson came from the young professionals: make a ‘pocket 
	edition’. Almost immediately one page versions of the work were made. One 
	compiled in question form is appended here. 
	As presentations and workshops developed, lessons were learned:
	
		- An effective way of presentation is to adopt a Socratic approach in 
		which it is expected that all the wisdom will be found within the group, 
		not the presenter. Depending on the level of experience and maturity of 
		the group, ‘elders’ may be invited to contribute.
- This approach requires the leader to be an enquirer.. Each point of 
		discussion may be commenced with a question such as “what does this mean 
		to you?” This allows the Principles as proposed here to become agenda 
		items. 
- The physical environment for these discussions is important. Small 
		rooms with chairs in an arc or circle, with no tables, have proved to be 
		effective. An auditorium, designed to focus attention on the presenter 
		alone, is not suitable, even counter-productive.
- In the majority of sessions held so far, participants have shown an 
		interest in focusing mainly on the behavioural principles – ethics. This 
		has been accommodated by getting the group to consider and resolve 
		ethical dilemmas and using their considerations to evolve a dilemma 
		resolving process.
- Not all participants can be expected to be comfortable with a 
		non-instructive environment. Some have expressed a preference for a mix 
		of tutorial and dialogue. This is a reminder of the challenge for the 
		presenter: to be not authoritative while controlling the process, to be 
		aware of the vulnerability of each participant, to acknowledge the value 
		of the mishap or mistake, to share stories without imposing his or her 
		values.
- In recognition of the likelihood of each participant gaining 
		different benefits from the exercise, and the value of each better 
		understanding the other, participants have completed short journals 
		before leaving. The recorded points and observations made have been 
		assembled and circulated, without disclosure of origin, by the 
		presenter.
From this last point, the value of the work has been confirmed. One of 
	the most common comments has been in relation to every professional, 
	regardless of occupation or station, having a client and the occasional 
	difficulty of identification of the client. For many the Contextual 
	Principles have been identified as being particularly useful. Younger 
	participants have remarked on their better understanding of the complexity 
	of the demands of professional life. Others have found stimulation in coming 
	to terms with the abstract nature of Principles, particularly those of 
	ethics. The authors have been encouraged to hear that versions of the 
	‘pocket edition’ have appeared on office walls; and that dilemma-resolving 
	processes developed in the workshops have been used in real-life 
	circumstances.
	The most memorable line of feedback came in the words: “ ‘the ABC of 
	x,y,z’ will add to my confidence in standing up to my boss”. 
	9. REFLECTION 
	The principles as have emerged through this work are not clear laws or 
	rules which any person involved in the spatial sciences can be expected to 
	follow. Simple in their framing and written in the abstract, Principles 
	depend on expert knowledge and experience in their application. In other 
	words, the principles lead us to the domain of the professional. They 
	separate the professional from the ‘average’ practitioner or the layperson.
	
	Being constructed in abstract terms, Principles defy codification. They 
	can have many meanings. The question: “how can Principles be passed from the 
	experienced to the less experienced?” was asked earlier. And having being 
	compiled by just two authors (with the help of their reviewers), the 
	Principles proposed here are not authoritative, yet have not been challenged 
	so far. 
	Recent experiences of discussing Principles in a collegiate or ‘workshop’ 
	environment lead us to think that the Principles can be nurtured and carried 
	on by the asking of the simple question of each of the participants: “what 
	does this principle mean to you?” Answers may be initially based in the 
	abstract but will shift to experience – stories which illustrate meaning. 
	The many shared answers allow the sharing of wisdom, embedding Principles in 
	the consciousness of the group members. 
	“The Ten Canoes” (de Heer 2006), a remarkable film of myth, metaphor and 
	cautionary tale, set in Arnhem Land in Australia’s far north, provides a 
	useful analogy. Firstly, the story is not short. Learning occurs during the 
	story as well as its conclusion. Secondly, the sharing of a story raises a 
	wide number of related issues and achieves a range of outcomes depending on 
	the life experiences of the listener. For some, the story refreshes the 
	listeners’ lessons of the past; for others, the story provides new insight 
	into aspects of life not fully considered. 
	Sharing the 21 Principles in the way described here is about as close to 
	the campfire conversation that we can expect to get in the 21st Century. In 
	light of our experiences, it would be appropriate to rename ‘Principles’ as 
	‘Questions’ as questions invariably lead from the abstract to the tangible 
	by way of stories. 
	Story-telling, the most ancient form of communicating and development of 
	understanding has its place in modern professional development.
