This workshop introduces students to the powerful Geographic Resources Analysis Support System (GRASS) GIS software to manipulate raster and vector data. We will see the graphical user interface and use simple BASH scripts to automate many common geo-data processing tasks such as cropping and re-projecting images. You will learn how to script processes for complex geo-functions.This workshop assumes BASIC KNOWLEDGE of BASH command lines and basic knowledge of Geographic Information Systems concepts (projection, buffer, overlay, etc…). Participants will need a pre-installed Linux Virtual Machine in their own laptops to follow the workshop.
