[GRASS-user] ArcGIS, GRASS and employability

I couldnt agree more with the previous postings. GIS is about concepts, not
about learning which buttons get you to an end result. Given infinity, a
monkey could write a work of Shakespeare. Given even less time, a monkey
could press enough buttons to perform "GIS Analysis" using the ESRI suite.
On a previous post someone replied with something that has really stuck with
me. It may have been Dylan. (quote not verbatim) "Using a computer graphics
package does not make one an artist. Using a word processor does not make
one a writer. Using GIS software does not make one a GIS Professional".
The key here is that GIS is about the concepts and analytical capabilities,
the chosen software is just the tool to do it. GRASS is an excellent tool
for many reasons.
Now for the bad news: Living in the US where ESRI is dominant (easily seen
on job postings), I would have to unfortunately admit that it is important
to at a minimum be able to say you have used ESRI ArcMap when job hunting.
Unfortunately (from a US perspective), much like "computers" are synonymous
with Windows, GIS is synonymous with ESRI.
Now for the big "However...". For companies/agencies looking to start up
GIS or take it to the next level besides simple editing and map printing, or
even migrate away from an ESRI suite due to the enormous yearly "maintenance
fees" & bugs, GRASS and other open source GIS and databases have *huge*
advantages. From experience I can say that since ESRI re-wrote their GIS in
2000 to "ArcMap", the quality of the software has tanked. In retrospect I am
thankful, because it is what drove me to open source GIS like GRASS. One
obvious drawback to ArcMap is the massive costs. Take the startup costs
alone (these are from memory and may be dated they are *not* exact quotes):
ArcMap Arc/Info = $14,000USD. Raster analysis extension = $2,500USD.
2.5(3d) analysis extension = $2,500USD. (those extensions may be
$5,000)
Looking at it from a student's perspective, think of how much power is given
to the student to be able to go to an agency or company and say "ArcMap...
yeah I can use that software. But if you really want cost savings and a
robust, scalable GIS, you might want to consider GRASS GIS on Linux or Mac.
The initial cost savings are in the tens of thousands of dollars, the
quality of software is far superior, and there are no yearly maintenance
fees." That is empowering and enriching students rather than robbing them.
So, the answer has two "yes's". Yes, due to market saturation (in the US),
students should be equipped with the knowledge to push ESRI buttons. And
yes, learning GIS concepts and applications for real world applications
should be done with open source software GIS such as GRASS as it causes the
student to come away with a solid understanding of what GIS is and how it
works. Also given the fact that GRASS is part of many open source GIS
solutions, students can then explore other open source GIS software like
GDAL/OGR, Quantum GIS, Mapserver, and PostGIS/PostgreSQL.
Take the semester to teach GIS concepts with GRASS GIS on Mac/Linux. Then
take a day to show how to push buttons on Windows/ArcMap. Be sure to
explain open source advantages and how to join the revolution. Then let the
students make the decision. It will be an easy one.
