Summary

This course provides an introduction to PostGIS and its most important features and capabilities. From spatial data types to spatial joins, the training will cover all topics concerning quickstart spatial data management and analysis within PostgreSQL. Along with gaining theoretical knowledge, participants will work with real-world datasets to deepen and reinforce their practical skills.

 

Basic experience with PostgreSQL is required.
