GRASS GIS

GRASS GIS (Geographic Resources Analysis Support System) is an open-source software used for managing and analyzing geospatial data. It enables users to visualize, manipulate, and model geographical information, such as maps and satellite imagery. With tools for tasks like terrain analysis, hydrology, and land-use planning, GRASS GIS supports various applications in environmental science, urban planning, and resource management. Its flexibility and powerful capabilities make it popular among researchers, government agencies, and anyone working with geographical information, without the costs associated with commercial software.
