OSGeo Python Library

Motivation

Several OSGeo software projects support Python. However, a global abstraction layer is lacking which would help to do "OSGeo Python programming". We think of well documented bindings to the various software projects which are handled as plugins (or whatever appropriate).

Functionality

Shared functions may include

• Import/Export of data
• Linking to external data sources
• Reprojection tools

Programming Language

• Python
• SWIG
• ...

Existing code to be recycled

• http://fwtools.maptools.org and http://openev.sourceforge.net
• GDAL/OGR Python bindings
• Mapserver Python bindings
• QGIS Python bindings
• GRASS SWIG Python bindings
• PCL and PrimaGIS
• ...
