Here's the promised summary:

Here is a quote from the manual:
"The software is furnished under license.  It is intended primarily as
a low-cost vehicle for teaching and scholarly research.  Accordingly,
generous academic, student and research licenses are available on
request."

	I don't know all that much about IDRISI myself, but a colleague
	of mine in the Soil Science Dept. uses it. I do know that it
	is a raster based GIS, runs under DOS (yuck), is fairly cheap
	(should be under 100 pounds)... well, that's it.

The most recent address I have is

The person associated with the software seems to be a fellow by the
name of J. Ronald Eastman.

Subject: IDRISI


Thank you for your interest in IDRISI. Enclosed is a brief product 
description and ordering information. We hope to hear from you soon.

IDRISI is a raster based geographic analysis system for use on IBM PC's and PC 
compatibles. The system consists of over 100 independent modules that can be 
run separately, or accessed through a unified menu system. IDRISI was created 
to provide an easily available GIS for research and teaching applications. 
Independent modules and simple data structures combine to provide users the 
capability to build models and add their own program modules to the 
distributed set. Required hardware is a PC or compatible, monitor and dot 
matrix printer. Recommended hardware includes a 20 MB minimum hard drive, a 
VGA monitor, and a mouse. Support exists for most dot matrix printers as well 
as the Hewlett-Packard line of DeskJet, LaserJet and PaintJet, as well as the 
HP 7475 plotter.

Functions included in the IDRISI system include basic GIS functions, Image 
Processing, Spatial Statistics, Vector/Database manipulations and a full set 
of data import and export routines. GIS functions include overlay, area and 
perimeter, surface analysis and map algebra. Image Processing covers the 
computer assisted interpretation of satellite data, from the creation and 
manipulation of signature files to the classification of images using both 
supervised and unsupervised classification methods. Spatial Statistics provide 
routines for statistical analysis with an emphasis on spatial description, and 
includes autocorrelation, trend surface analysis, linear regression and 
weighted mean center and standard radius. Vector/Database manipulations allow 
the user to interface vector files with a dBase III or IV database, and map 
the results using the cartographic description language in the Plot module.
IDRISI also contains a vector editing/digitizing program, TOSCA.

IDRISI has a set of modules to import and export a wide variety of formats 
from other GIS and image processing programs including Arc/Info and ERDAS, and 
to transform data from U.S. Geological Survey DLG and DEM files. 

IDRISI costs $560 US for general use, $280 US for academic, research and other 
non-profit organizations and $140 US for students. Shipping is $9 for 
shipping in the US, 15$ US for Canada, $25 US to Mexico, $41 US to Europe 
(except France), $32 US to Central America, $48 US to South America and 
$58 US to Asia, Africa and Australia and France.  Funds must be drawn in US 
dollars from a US bank, or an international money order. We will accept 
personal checks, purchase orders or MasterCard or Visa (a new service).  Note 
that IDRISI now only accepts prepayment.  In order to recieve the student rate, 
students must be full-time, and submit either a copy of their registration or a
paid tuition bill.

Institutions wishing to purchase the IDRISI software system for use on 
multiple computers (whether networked or not) may purchase licenses at a 
considerably reduced rate according to the following policy:

1.  One master license must be purchased at the normal rate.  This will be the 
registered copy to receive update notices and from which all working copies 
will be made.  

2.  Licenses are sold in packets of 10 for $1400 US, half the normally 
applicable rate per copy, excluding shipping and handling.

For more information regarding site licensing contact IDRISI.
