Hi,
This brings to mind an additional point. Even though OS GIS tends to
be a patchwork of projects that demand a good deal of experience from its
users, it also gives you infinite extensibility.
From a business perspective, this affords a proficient user of OS
the ability to exploit automated workflow processes. Many use cases involve
repetitive drudge work that can be automated if you have access to the code
and/or knowledge of scripting. This is often possible with commercial
products too, but OS usually has more hooks to feed a workflow and you can
resort to the code if required.
Since we are in the internet era, workflows tend to get pushed
further out into the cloud which is why WPS has a lot of promise and means
that the push button=> result will be mandatory. The public use of GIS
workflow demands simplicity, possibly over simplicity.

Subject: [OSGeo-Discuss] RE: Comparison between Proprietary and OS
I'm very new at OS, have worked 10 years on AV3.x and a little Idrisi, but
only from a vegetation point of view, so we're talking basic end-user
digitizer mapper (and georef images), bit of topographical modeling and
extracting underlying information. I wanted to do OS when starting my own
company, but time constraints had me take a loan to get Windows Office and
ArcView, just because I knew what I would get, and be able to get up and
running on it within a week. I now realize most of the things I need to do
in day to day, I could do in OS Q-GIS albeit with a little less sleekness.
But I could not risk letting work slide (or causing clients, who use ESRI,
hassles) to get up and running in Q-GIS, GRASS and possibly OSSIM.
So the hurdles for me to OS were "acceptance" specifically for the following
reasons:
Free and easy access and training of ESRI at varsity. Autocad did the same
and look where that got them.
Linux, just mentioning command lines has me a little nervous. (I know this
is changing, but the field calculator is enough programming for me, thanks)
I'm not suggesting anybody is obliged to fix these things, I mean there's no
such thing as a free lunch. I'm just saying what OS inherently is, is
probably going to keep it out of the mainstream (non-programming) end-users
easy reach.
So in short I am doing what somebody already suggested, get ESRI for day to
day soft landing and learn OS GRASS and OSSIM meanwhile for real work;-)
Hopefully in a while I'll wonder what the fuss was about... and possibly
contribute, if only to the dummies FAQ section.

Hi,
this is the kind of question I face when in my lectures evangelising OS GIS.
ArcGIS has many tools, though some prefer to call it a deluge of tools,
which almost distance the user from understanding the concept of GIS.
Auto Complete Polygon:
In Qgis which is a very userfriendly OS GIS you have 'Cut polygon', do try
and find the difference.
Polygonising from lines:
Open JUMP has one of the most userfriendly approaches.
Create lines and polygonise in OpenJUMP and the software automatically
creates a folder for Dangles (un-wanted line pieces)
The query is more for Vector GIS, I suppose.
GRASS GIS:
It has so many features for Image analysis and Raster GIS, the commercial
GIS need a barge pole to even touch it. The vector Part of GRASS is robust
too.

We are working on that:
http://grass.osgeo.org/wiki/WxPython-based_GUI_for_GRASS#Digitizer
Screenshots:
http://grass.osgeo.org/screenshots/gui.php
-> wxPython (new GUI)
You can try out the prototype in GRASS 6.3.0 (released yesterday):
http://grass.osgeo.org/announces/announce_grass630.html
Get MacOSX, Linux and now even native MS-Windows binaries with *installer*
at
http://grass.osgeo.org/download/index.php#g63x
Enjoy

Ravi,
What us Open Source evangelists are missing is an honest comparison
between ESRI desktop applications and Open Source equivalents.
What is it about ArcView and ArcGIS that people really like, listed
feature by feature in a table.
Then identify whether Open Source covers it and how.
Very important is to address usability. How quickly can an Arc* user
migrate to Open Source?
My skill set is lacking here as I don't have much experience in either
ESRI or the Open Source desktop tools. It seems like you have experience
with both which puts you in a unique position.
Is this something you, or one of your students would like to investigate
further? Maybe build a table similar to this one:

This has been done somewhat. You might find it interesting reading.
