What is GRASS?
GRASS is a geospatial processing engine for advance analysis and visualization of geospatial data. GRASS is a free and open source software, released under the GNU GPL.
Tools
GRASS provides a wide range of tools for geospatial processing, modeling, analysis, and visualization, with detailed documentation to guide users through processing raster, vector, 3D raster, and temporal data.
Interfaces
GRASS provides a number of interfaces for interacting with the tools and developing computational workflows. The most common interfaces are:
- Command line, also know as terminal or shell
- Python
- Jupyter Notebooks
- Graphical user interface
