*** reply ***

The document that lists the format & form of the Vector Product Format is:

	Military Standard
	Vector Product Format
	MIL-STD-600006
	13 April 1992

This 200+ page doctument has a complete discription of the format.

I received mine from:

	(703) 285-9240       -    I'm not sure about this phone, I wrote them.

Since the VPF has been created as a means for transmitting digital geographic 
databases, I, for one, would be interested in any programs that make use of the 
format.

Thanks.

I don't have a direct answer, but your question has prompted me to pose a
similar one that I have been nursing for a while. It seems to me that we toss
around concepts of map layers and geographic themes in general without a great
deal of analysis. At the most straightforward level, layers contain those
physical features which one wishes to drape on top of the basic topography
(2D or 3D), such as soils, vegetation, etc. At a more abstract level, layers
can contain 'features' which are subject to far more interpretation, eg,
political boundaries; with possibly the most extreme case represented by the
use of some analytic model to generate regions of locational suitability. This
classification becomes slightly muddied by the fact that some geographic
features can be quite transient, viz, watercourses.

These qualitatively different layers can all be overlayed with gay abandon in
many systems. I am wondering whether there would be merit in injecting more
constraints into an advanced GIS. Is there some seminal reference on the nature
of themes which I should be reading ?

   Re: Chris Hermansen's thoughts.

  I appreciate the response, although I disagree with much of what you say.
  One nice thing about a non-homogeneous world is that various locales
provide specific concrete examples of various principles that may not be
available even within large countries due to "local homogenization." (Such as
socialized medicine enforced across an entire country.) I would simply point
to Hong Kong as an example of the successful application of a wide variety
of free market principles, including non-regulated taxis. From a reading
viewpoint, I recommend Henry Hazlett's classic "Economics in One Lesson"
that has not lost relevance despite its age (probably 40 years). It is an
excellent source of debunking of a huge variety of still commonly accepted
economic falsehoods. Ludwig von Mises is also excellent, as is Fredrich
Hayek, although both are less approachable being written in a more academic
style.
  America leads the world in software. One significant reason is the lack of
government red tape, which, if it existed, would have made Microsoft, Apple,
et al. quite impossible. I think most proposals for regulating this or that
come from sectors that would enjoy being either directly or indirectly
involved in setting standards and otherwise pushing around other people.
There is no evidence for, and all evidence against, the notion that
government bureaucrats or consultants thereof provide superior intelligence
and competence to anything. All they provide is a gun, aimed at superior
producers and intellects. That is the nature of government as such, in
today's world (I am not an anarchist; the only PROPER role of government is
in apprehension of objectively defined criminals (those who initiate force
or fraud), protecting against external military force, and adjudicating
contractual disputes.) One basic assumption behind those who believe that
a law (often arbitrarily defined and enforced) is the solution to all
problems is that force and fear solve all problems. This is a despicable,
and scientifically, wrong, view of human nature and reality in general.

OK, so the consensus is that people don't want software developers making
decisions about the legality of GIS operations (and rightly so). Having said
this, there is still a burning need (IMHO) for systems which are more task
aware, in order to do things like provide intelligent advice. So I've rephrased
my original question in order to make it even more rhetorical :-) Let us say
that in a future object-oriented world, we are faced with the decision of
whether there would be any value in classifying map layers into different
categories, in order that these layers can have individual properties and
behaviours. My question now is what the nature of these individual methods
might be ? There are some obvious applications pertaining to data quality, eg,
one might wish to flag to users that they are attempting to overlay data sets
of widely disparate resolutions, or that there are problems in combining
continuously measured variables with categorical data. Stepping beyond
concerns of data quality, however, it is interesting to speculate on the
utility of classifying layers according to semantic content. Ideas anyone ?

Well, my philosophical and very opinionated bent on the subject of
injecting constraints on "acceptable" operations in GIS runs along
these lines....

I freely accept the constraints on my analyses that result from my
adopting a digital and mathematical/logical model of the world -
although I should remain conscious of these.

I grudgingly accept the further limitations on my research caused by
what operations my box and software can manage.  I have neither the
time to program all the necessary amls or whatever to do everything I
want, nor the money available to buy a enhanced system, as though a
Universal Turing GIS even existed.
I should be more aware of the consequences of these limitations.

I would kick and scream madly if my software package tried to tell me
what constitutes acceptable research methods - part of my purpose as a
researcher is to develop new methods of analysis, and any imposed
constraints in the software are going to reflect Least Common Denominator
status quo opinion.

If individual users wish to impose an in-house code of acceptable
operations that can be performed, fine.  I think that can be
incorporated into the software as a security matter - certain operations
could require an autoration code, much as long-distance calls do in
many contemporary telephone setups.

I don't think you can idiot-proof everything without reducing everyone
to the level of idiots.  That's the opinionated part I promised earlier.

Subject: Map Layers and Overlay
Date: 21 Jul 92 13:56:09 GMT
Organization: Dept of Computer Science, Heriot-Watt University, Scotland

Hi,

I am currently involved in a project which studies modelling geographic data.

I have a question concerning the definition of a map layer and the use of the overlay operation from both the map user view (assuming that there are no modelling constraints) and the way these are handeled in current GISs.

I am particularly interested in the following,

***For a geographic database user,***

1. Does a map layer usually constitute one object type for example, roads map layer, sewer utility lines map layer, houses map layer, and so on ?.

2. Or can one map layer contain more than one object type?, for example, road network and houses on one map layer.
If so, are there any constraints on the type of objects that could be included in one map layer, (for example, objects should not overlap).

3. In the case that one object type (for example, land use region), has as boundary another object type, (for example, road boundaries), does that mean that there are two object types on one map layer.

***In current GIS's for example ARC/INFO***

1. Does the handling of map layers conform completely to the users view.

2. Is the user able to say overlay map layer 1 with map layer 2, or does he have to specify every object in the map layer in order to either display it or make an overlay operation with it. (That is of course, if it is the case that one map layer can contain more than one object).

3. Can the result of an overlay operation be stored as a new map layer.
And in this case, Is there any constraints on the combination of objects that constitute the resulting map layer.


Your help and comments are very appreciated,

The BibTeX format would probably be more useful, and it too is ASCII
format.  It is easier to convert from BibTeX to Refer than vice versa
(and I have done a lot of this over the years, going both ways having
originally built my database in refer format), and the BibTeX format is
considerably more self documenting and informative that the Refer
format.  As far as availability of tools, most (if not all) refer type
tools I know of have equivalents in BibTeX, freely available, and TeX
is (arguably) more widely used now than troff, for which the refer
format originally lived.  I have a large collection of bibliographies
(2000 or so, not particularly GIS though) in BibTeX format (and still
some in refer format awaiting clean conversion), with a variety of
tools for querying the database, and entering new entries.  Finally,
one is limited to single characters to recognise fields in the
bibliographic entries in refer, a limitation not found in BibTeX.

The GIS Master Bibliography certainly sounds like a very worthwhile
project.  Similar bibliographies are available for free, on-line, in
other disciplines, including  Artificial Intelligence.  They are
exceedingly useful, allowing querying by email, etc.
