Geophysical data collection is increasingly moving from Grid based data collection to Real Time GNSS Located systems. While a number of commercial and proprietary systems exist for collecting such data few commercial geophysics softwares exist to facilitate the processing of such data. Python is a human readable Open Source programming language with bindings and modules available for nearly all standard geospatial data types. Some of these are available through Open Source GIS packages such as QGIS however the majority are more powerful and extensible when utilised directly through Python. This talk will initially discuss some of the widely available modules available for processing and manipulating and presenting geospatial data. These include:

•PyProj
•GDAL
•Shapely
•Fiona
•SimpleKML
•DXFWriter

We will then introduce work being done at the University of Bradford and GSB SUMO to build a python package for the processing of geophysical datasets. This includes:

•Manipulating GNSS NMEA Strings
•Projection of GNSS Data
•Image Processing
