Help: GIS

P: n/a
Hi,
I am new in GIS area and need your suggestions for where I can
start from. I have a python based web application with a database.
Now I would like to add a GIS map into my application. When a user
clicks a certain area in the GIS map, it can grab the data from the
database via my python based application. Do I have to use MapServer
or Grass or some other backends for this purpose?
Thanks a lot.

While I am not a part of our GIS department, they use ArcGIS which has
Python support built in. If that's what you're using, you should be
able to use the examples given on ESRI's website:
http://www.spatialvision.com.au/html...ython-arc9.htm

Hmmm...not much there. Here are some other links I found:

http://nrm.salrm.uaf.edu/~dverbyla/a...hon/index.html
http://www.ollivier.co.nz/publicatio...hop/sld008.htm
http://www.3dartist.com/WP/python/pycode.htm

I don't know if these will be much help. You really need to just dig
in and start coding. I would recommend "Programming Python 3rd Ed." by
Lutz if you want something in hard copy. "Dive Into Python" is a free
book that's online that I'm told is very good. Both have good
examples, some of which are involved. All the web oriented Python
books are a few years old, but the code in them still works, for the
most part.

Mike, Thanks for your suggestion. I am looking for a python GIS
package (without any other GIS backends like mapserver) which can be
simply imported into my current python web application. I am not sure
if it is available. So far, the close one I found is Python
Cartographic Lab. But I can not find any examples for PCL. Anyway, I
am still on the way of the deep learning curve for GIS.
