The default solution you should use is to write a Python script which will run inside GRASS session (i.e. Also, it supports different database interface such as ODBC, DBF, SQLite, PostgreSQL, and MySQL. Your team can keep locations on central servers with underlying map sets while working on similar project DBs.įurthermore, GRASS GIS provides robust capabilities such as 3D raster (voxel), raster, DTM, and point data analysis, geocoding, image processing, map creation, visualization, temporal frameworks, geostatistics, landscape structure analysis, erosion modeling, solution transport, watershed analysis. GRASS GIS supports workgroup via mapset/location concept and can share data through the Network File System. It also works with different printers, plotters, digitizers, and databases. It supports command line syntax and graphic user interface. GRASS GIS is composed of more than 350 modules that help users render images and maps and manage location-based information.īesides those functions, GRASS GIS can also be used for raster and vector data, spatial data designing, multi-spectral image processing, storage, and manipulation. In time, this simple tool has turned into a multi-functional system that provides a broad range of useful utilities for scientific research and academic institutes, NGOs, government agencies, and commercial settings. ![]() Army as a land management and environmental planning solution. GRASS GIS is an open-source system and this is one of the reasons why it is more beneficial compared to other similar software. Tutorial 3 - Sample Project - Start GRASS GIS with sample project. The main benefits of GRASS GIS are data management, image processing, and its open-source nature. Will show a few basic commands to familiarize users with GRASS GIS command syntax.
