In addition to reviews already mentioned, IDRISI will be reviewed in detail in
an upcoming PE&RS issue. The particular issue has not been decided yet, but
the review is in the pipeline and should be out in the spring. Anyone wanting
information about IDRISI version 4.0 should feel free to contact us at
IDRISI@VAX.CLARKU.EDU.

A local VAX enthusiast pointed out to me that in Arthur C. Clark's book
(and film) "2001, a Space Odyssey" came out, the computer which featured
therein was called HAL. Whether intentional or not I don't know, but each
initial in the name 'HAL'is "one step ahead" of those in the name of the
well-known PC manufacturers and developers International Business Machines
(IBM).

However, the operating system for VAXen is the Virtual Memory System, or
VMS. And if you compare 'VMS' to Windows NT ('WNT') you find that the Digital
product is also one step ahead...

...But I am sure any comparison ends with the acronyms!  :-)

To follow the interesting thread..

After just completing our Intro GIS course and projects,

Data Format Translation
Misundestood System Function/Behavior
Finding Appropriate Data
Lack of macro implementation for repetitive processes
Misunderstood Command Syntax
Failure of Hardware

These would probably come up as our biggest problems.
All of the students, except for those very few, were very motivated.
There is always a time crunch, especially when waiting for a gov't dataset.
Our biggest problem was definately translation of Arc Covs to Idrisi or Grass.
But we figured it all out.

I would appreciate hearing from those of you who are running idrisi from a

        what problems did you have to overcome to operate the package
successfully on individual terminals?  what solutions were employed..?

        to what extent can local hard disks be sacrificed (to minimise
management problems in a teaching environment) and all storage be centred on
the NFS......?

        any tips that would be useful to a novice network manager..??

thanks in anticipation!

One could certainly update the tesselation at whatever interval desired,
whether a fixed interval or only when an element changes.  In some
ill-conditioned distributions of control points, however, the Voronoi 
tesselation can change dramatically just by adding or removing a few points 
in strategic locations.  In this sense, variables such as "spatial 
resolution" (depending on how it is defined) and spatial gradients 
derived from Voronoi tesselations _can_ be highly sensitive to small 
changes.  In most instances,  this probably is not a good feature of 
Voronoi tesselations.

Absolutely, it would be so nice to have compatibility at all scales.

Any ideas?  professional organizations he could contact?

Martin, You should check out Foleys et al.
Computer Graphics book.  They discuss your
problem in detail in a chapter about
Curves and Surfaces as far as I remember.
I'm sorry that I can't provide you with
any C code, but I think the book has
some code you might look at.
By the way, it shouldn't be that hard to 
modify the code in the book.

Gute Weinecht, und ein gutes Neue Jahre

You write:

I know that sometimes this method won't find arc correctly.  Try this:

  &sys xterm -e $ARCHOME/programs/arc

or substitute the value of the environment variable ARCHOME.  The same
thing will work with INFO:

  &sys xterm -e $ARCHOME/programs/info

I hope this helps.  I am still a little confused about what you want

Confession: Ilearned ERDAS from the manuals, but I had learned ORSER
from the manuals.  The task requires a firm grasp of the fundamentals
of remote sensing and multivariate statistics, and a lot of time.
Trial and error is absolutely necessary, as well.
  You must establish a clear goals and a clear plan for acheiving
those goals.  If you want a real chalenge, try writing a supplemental
program usig FLECS and the ERDAS TOOLKIT!  Good luck.

One question on my Intro GIS final exam asked students to
indicate the most vexing problem encountered in their
individual term projects, and to indicate how they would
avoid that problem in in the future.  

The following is the distribution of student-identified
problems across six categories that emerged in the answers.

 ****| Finding Appropriate Data 
  ***| Motivation / Time Mgmt 
  ***| Misunderstood System Function/Behavior
    *| Data Format Translation 
    *| Misunderstood Command Syntax         
    *| Failure of Critical Hardware (CD Drive) before Deadline 

How does this fit with other's experience with "real" projects?

Because I haven't yet convinced the Powers That Be at MapInfo that Internet

Bill,

I have a shareware program called MacAstro that plots out the location of
stars and planets in the sky as seen from a given location, day, and time.
I plugged in a latitude of 44 30'N, a longitude of 110 30'W, a date of
8/2/89, and a time of 11:40.  The answer it spit out for the suns location
was Azimuth = 269 19.02' and Altitude = 24 59.40'.  Does that sound about
right?
