GRASS is one of the eight initial software projects of the Open Source Geospatial Foundation. The GRASS development team is a multinational group consisting of developers at many locations. Running GRASS GIS for the first time, a folder named “grassdata” is automatically created. When launching GRASS GIS for the first time, you will open a default Location “world_latlog_wgs84” where you can find a map layer called “country_boundaries” showing a world map in the WGS84 coordinate system. And they relate in the way that Qgis can display and edit GRASS vectors through the GRASS plugin, preserving the topology. QGIS is primarily non-topological or “spaghetti”, adjacent area boundaries are duplicated. GRASS has full/real topology support, that means that a single boundary can share several areas. What is the difference between QGIS and GRASS? They compliment each other well and you can even use the QGIS GRASS Toolbox to load in GRASS data directly, and run GRASS processing commands from the QGIS menus. Whereas GRASS GIS focuses more on data processing and analysis, QGIS focuses more on cartography and map making. ![]() What is the difference between QGIS and QGIS with GRASS? Within this directory, the GRASS GIS data are organized by projects stored in subdirectories called LOCATIONs. ![]() This directory, often called grassdata, must be created before you start working with the GRASS plugin in QGIS. GRASS data are stored in a directory referred to as GISDBASE. ![]()
