Processing Geodata using Python and Open Source Modules Geodata ?

Geographic data and information are defined in the ISO/TC 211 series

  • f standards as data and information having an implicit or explicit

association with a location relative to the Earth. Approximately 90% of government sourced data has a location

  • component. https://www.iso.org/committee/54904.html

GIS – Geographic Information System

GIS is a system designed to capture, store, manipulate, analyze, manage, and present spatial or geographic data. Popular GIS are for example ArcGIS (ESRI) and QGIS – both can be extended by using Python.

Python ?

This talk will show you the basics of manipulating, analyzing and presenting geodata using Python (in the Jupyter Notebook.)
