Analysis with QGIS

To learn how to do raster and vector GIS analysis, joining the power of tools like GRASS, SAGA, Orfeo ToolBox, etc. with the ease of use of QGIS.

The course is aimed to who wants to learn how to use the GIS to do predictive analysis. Is adviced to have at least basic knowledge about SIG software.

We suggest to have a basic knowledge about QGIS.

Course outline

• Available alternatives in QGIS: which is most suitable for each purpose
