Thanks to all who replied.  Several people responded that they use ERDAS
to accomplish these tasks.  Keith Clarke indicated that the source code
for a C program included with his book _Analytical and Computer Cartography_
could be modified to accomplish these tasks as well.  I soon realized though,
that I had the tools I needed in PC ARC/INFO.  The TIN module reads the DEM
into a point file which could be joined to another DEM derived point file
or broken apart by various means.  I can then take the newly derived file
and process it as I want.

There is a whole suite of graphing commands available in Arcplot 6.0.
A scatterplot can be drawn using the GRAPHPOINT command.
Other relevant commands are,

GRAPHEXTENT, GRAPHLIMITS, AXIS & AXISRULER.

At what point in the ability to perform spatial analysis does one package
fail and another succeed?  While I agree that overlay and buffering are
important functions, are they the deciding factors in whether a system
qualifies as a GIS?  For instance, in the system I use, while it does not
have the ability to create buffers, it does have the ability to perform
radius searches of attribute data, in which a logical operation is performed
following overlay of a circle of defined radius.  This results in the selection
of the records which fall within the radius.  I do not know of other types
of analytical tools which can perform this function.  The spatial relationships
are critical to this analysis.  Isn't that what GIS is all about???

There is a lot of talk about GIS being a $1 Billion/year business now,
and projected to be $3 Billion/year by 1995.   Where do these numbers
come from?  What are the breakdowns?  It just doesn't seem that all the
consulting and software/hardware could be that much.  I realize research
plays a role in this figure too.  Does this number count things like
all GPS work, remote sensing?  Any help in this would be greatly
appreciated.   Figures from other countries are welcome too, but I
think the $1 Billion figure is just for the US...?

Hello, netters & GIS-ers:

First off, a disclaimer:  I am speaking for my home department
in North Carolina, not the institution whose name may appear 
above.

We (in NC) are seeking to enhance our map-making abilities by
purchase of a scanner, digitizer and plotter to work with our
Suns and hopefully our Macs as well.  Software will be mainly
PD stuff like GMT, GRASS, etc, at least for starters.  Maybe
ARC/InFO too.  

Here's the wish list:

o Size 24x36", or better
o lowish cost (have $15k at most for all)
o color would be nice, but not absolutely needed
o decent user friendship factor
o access by Macs as well as Suns would also be nice
o decent resolution (300 dots) for scanner & plotter
o Postscript output for plotter (I dont know if such a beast
  exists)

Any advice would be very useful; the more specific the better 
(i.e. models, costs, maintenance, etc.).  Please email me directly
and I will post a summary if sufficient interest.

Thanks in advance.

Subject: Looking for FAST raster display software
Date: 14 Apr 92 01:58:03 GMT
Article-I.D.: amazon.1992Apr13.175803.1

I would appreciate any pointers that anyone can give me in regards to the
following set of requirements.

We are involved with a project that needs to be able to display raster
scanned maps, properly geo-coded.  The original source of the maps will
be from DMA.  The project has the following requirements:

The graphics should either be for SGI computers, or for X, or both, or
SGI's new GLX, or all of the above.

The graphics should be tailored towards speed.

We suspect that we will have to write a 'librarian' to manage telling the
graphics which maps are available (We think this will be a problem due to
the large volume of map data we expect to handle, and the fact that only some
of the data will be available on disk, much of the data will be available only
from slower storage systems)

Along with data from DMA, we also need the ability to display satellite imagery
from Landsat, Spot, etc.

We are not looking for a program or set of programs, rather a programming
toolkit in which to build our application on top of.

We are interested in both freeware, and software we have to pay for.

We are already familiar with ESRI and ERDAS, DeLorme, Merit, Genasys, Gemini,
Coryphaeus, and KRJA.  Most of these (at least in our initial survey) fail 
to meet our requirements for a variety of reasons:
	They are not programming toolkits.
	They are not SGI graphics or X based
	The graphics is not fast enough (a demand of our application is speed,
		speed, and yet more speed)
	Not designed to handle the volume of data ( 10Gbytes+ on disk, 1 Tbyte
		on Jukeboxes)

What we are looking for is a 'simple' (hah) package for displaying geo-coded
images (maps and satellite imagery), with associated tools for taking 
either stored or perhaps live satellite imagery and geo-coding it, to either
be able to either support the scanning of paper maps and geo-coding the result,
or to be able to work with an existing service company for the map scanning.

If you are aware of any company or software that might significantly contribute
to solving our problem, please mail me a message at shectman@amazon.llnl.gov
or reply to this news group.


Thank you.

Are you sure the product is not from Genasys rather than Genesis? Genasys is
an Australian company, with branches in the U.S. the U.K. and elsewhere, which
sells a very competent set of GIS products including Genamap (previously known
as Deltamap). They also tend to favour HP platforms though their products will
work on any generic UNIX machine.

If it is - Genamap accepts a wide range of input formats and is certainly not
restricted to IBM curiosities such as the EBCDIC character set. If not - sorry
for wasting bandwidth!

Thanks for your reply Peter, and I understand the "personal" nature
of the comments. The complexity issue is being dealt with under the
idea of the profile, a simplified sub-set of the standard. USGS and
the Census are committed to supporting the standard, warts and all,
as are several vendors.
There hasn't been much GIS-L discussion of the standard, and it would be
very appropriate right now, since NIST/USGS are holding a series of
workshops on the standard, including one next week at the San Diego
AAG meeting.
The issue of design-by committee is an old one. The two options were
for the USGS or someone else to "just make one up" and force it on the
industry. This approach has worked (TIGER, DEM, DLG etc) but is not
really USER-BASED. Design by committee is ugly, but it is democratic.
In the long run, I think its in everyone's best interest (including
ESRIs).
By the way, good luck on the maintenance programming on GCTP.

Usability, especially for sporadic users is an important attribute for a
GIS.  Given the amount of effort to teach students to use ARC/INFO, I have
it much more productive to introduce students to low end packages, such as
MapInfo and let their interests move them in the direction of more sophistocat-
ed systems.  I agree with Steven's assessment of the situation.

This is only marginally GIS related but does anyone know of software to
print a "great circle map" centered on a given lat/long? By great circle map
I mean essentially a circular map that shows where a radio signal (or crow, I
suppose) leaving your location would head, depending on the heading.

Anything on a PC, SUN, or VAX would be great, ability to import to ARCINFO
a big plus.

According to radio news reports I have heard, one of the primary
challenges faced in the former republics of the Soviet Union is the
creation of a reliable network for food distribution.  My interest
is in using GIS to ward off potential famine not just in the Soviet
Union, but anywhere it lurks.  We all have a general idea that a lot
of food is wasted worldwide, while at the same time people are going
hungry.  Questions to pose:

   o Can GIS really help?
   o Are existing world famine-relief organizations using GIS?
   o Can effective planning of food distribution be done remotely,
     i.e., without expert knowledge of the geographical area?
   o Are governments of starving nations willing to accept
     foreign planning of relief efforts, or would they insist on
     distributing it themselves, possibly in a corrupt manner?

Subject:      Global Land Info System

The people at the EROS Data Center have recently instituted a system
called GLIS (Global Land Information System).  It is designed to "Meet
the land data information and access needs of the global change science
community."  It is supposed to be an index of global data sets of all
sorts.  It can be accessed on line through the Internet, or through a
dial-up phone line.  Part of the system is an index of the AVHRR data,
which is archived and distributed through the EROS Data Center.  I have
seen a demo of the PC-based GLIS software and it is pretty slick.  You
can actually view a resampled version of the image (every 4th pixel, I
think) to see if it is really what you want, if there was cloud cover,
etc.

I had a pamphlet which listed email and internet addresses, but it is
being passed around the office now.  Call or write EROS for info:
