A location is a set of directories containing mapsets with a given coordinate system. The GRASS GIS database directory will contain locations which in turn contain mapsets. Google+: /u/0/b/115473297214719936733/communities/111147786674687562495 To start GRASS GIS, you need to set the GRASS GIS database directory, select a location, and then select a mapset.Unlike typical application software, upon starting GRASS, the user is presented with a UNIX shell containing a modified environment that supports the execution of GRASS commands (known as modules).

Note that the most recent stable version of GRASS GIS for Mac is 7.4. For Mac, follow the instructions to install the 'framework packages' after following the links from the main download page. General information about Map Projections: en./wiki/Map_projection GRASS is designed as an environment in which tools that perform specific GIS computations are executed. Go to and download GRASS GIS 7.6 (new stable version) for your appropriate OS. GRASS GIS Tutorials - Tutorial 6 - Starting GRASS GIS with a New Projectĭownload geod_pts_spm.zip from here: /ncexternal/index.html You will create a user MAPSET on your newly created LOCATION The system is designed to accommodate large projects and even multiple users in a Location but it is also useful for individuals who just want to keep their data well organized.

By this GRASS GIS is able to apply a specific system to organize the data.

The main component of the Data tab is the Data Catalog which shows the GRASS GIS hierarchical structure consisting of Database, Location and Mapset. You will learn how to define a GRASS Database and Location Name.

I will show how start a new project using the sample data provided with the GRASS GIS Installation. We will use a ESPG code so define our Spatial Reference System. On This tutorial I will show you how to define/create a new LOCATION with its MAPSET.
