Analysis and transformation of geospatial data using Python

Demeter Sztanko

Audience level:
Novice

Description

I will be covering some general concepts of geospatial data, main formats in which it is distributed and some common places where this data can be acquired. We will also learn how to read, process and visualise this data using Python and QGIS. I will also talk about some typical problems one can experience when working with geospatial data.
