PGIS3: PostGIS Raster

Synopsis

PostGIS, the spatial database, is able to deal with raster data (images) on top of its wide range of vector data features. Made for vector/raster data processing, the PostGIS Raster module will allow new use cases for geospatial analysis.

 

This training session will allow you to install and get your hands on PostGIS Raster for the main use cases.

Goals

The course will give you the following skills :

  • Know the main PostGIS Raster features
  • Be autonomous for data import and writing of raster/vector spatial queries
  • Know about the main performance issues and how to manage them
  • Be able to use PostGIS Raster with other visualization tools

Duration

2 days

Pre-Requisite

Having a PGIS1 : PostGIS Level 1 level is recommanded for this session
