I'm looking at putting together a light Python install on a thumb drive that I can take to client offices and do some basic GIS processing. I'm thinking of installing the following:

  • PyScripter
  • Python 2.6/2.7
  • Numpy
  • Scipy
  • GDAL/OGR with the Python bindings
  • GRASS, likewise with the Pythong bindings
  • QGIS

Does anyone have any suggestions of any libraries / software that might be a useful addition? Typically I'll be working with raster datasets, but any and all suggestions would be appreciated.

(I'll cw the question if people think that its appropriate).

Interesting project you have will it be available to the GIS community?

Maybe of interest Portable GIS http://www.archaeogeek.com/blog/portable-gis/

    Happy to put up a post once I've got it all set up and given it a whirl out in the "real world" – om_henners Nov 24 '10 at 23:28

  • Shapely for quick geometry work
  • xlrd because spreadsheets are ubiquitous

    Might as well add xlwt for symmetric Excel in/out – Jason Scheirer Nov 24 '10 at 18:26

NetworkX (<= 1MB) if you do any shortest-path processing.

You could start with the OSGeo disc and add anything that you think might be missing. You can do a lot with what's already on there.

I would certainly advice SAGA GIS as a portable tool for doing GIS analysis. There is a python interface also - though quite a lot of things can be done using the modules present. http://www.saga-gis.org

  • this would be a better answer if you linked to a page or discussion telling how to make Saga portable (or include the instructions within you're answer if they're short enough). – matt wilkie Dec 6 '10 at 23:10
  • @matt: the zipped version (windows) is portable – johanvdw Dec 9 '10 at 8:54
  • then put that in your answer! :) see the edit link – matt wilkie Dec 9 '10 at 16:14

BTW, there is already slaxGIS: http://geomatica.como.polimi.it/software/slaxGIS/index.php

It comes with GRASS 6.4.0, MapServer 5.6.5, OpenLayers 2.10, uDig 1.2.0, OpenJUMP 1.3.1, Zoo WPS 1.0.0, PostgreSQL 8.4.4, PostGIS 1.5.2, and libraries such as Proj, GDAL/OGR etc.

Maybe it is easier to either customize that or to ask the authors to include new packages in case some space is left.
