Python GIS

Some Python programs useful for GIS.

• pygps, a Python GPS
• mapview, a Python map viewer
• LatLongUTMconversion, a Python library to convert between Lat/Lon and UTM
• ccintersect, a Python library to calculate the intersection of two circles.

Tarball of source code. There's a binary ipkg in the unstable feed of Familiar.

Documentation

How to get maps. Yes, there are some bugs.

Open Source License

GPL .

You can download the current version. Requires python, gtk, pygtk, and libglade. If you are running Fedora Core, you already have all of these. Also requires my LatLongUTMconversion (below).

Roadmap

• Allow mixing between Colorimage and Topo.
• Smooth zooming between scales.
• Write shapefiles, or else just use OGR to be able to write anything.
• Should be able to create a waypoint (single point datum rather than a line).
• Should be able to to create a polygon (area rather than a line).

This Python library code converts between Lat/Long and UTM. I use it in Pygps, Mapview, and a few other programs. This same algorithm is available in libproj. There are python bindings for libproj in Thuban. Thuban is good, but I don't want my code to depend on Thuban. Also turns out that there are independent Python bindings for proj.

Downloading

You can download the current version.

Installing

Unpack it, and run "python setup.py install" as root. That will install it in your site-packages directory and byte-compile it.
