What is GRASS GIS?

GRASS GIS is an open-source and free GIS solution that offers geospatial analysis and data management, maps and graphics production, image processing, visualization and spatial modeling capabilities. A project of OSGeo, the platform works well for academic institutes and various commercial settings around the globe. Environmental consulting companies and government agencies can also take advantage of the open-source software to analyze location-based data and manage it efficiently.

The software is available for all major operating systems i.e. Windows, Linux and Mac OS. The platform is an official project by OSGeo (Open Source Geospatial Foundation) and is distributed under GNU GPL (General Public License) V2, which means that anyone is able to use the software and has access to the source code for further customization.

Overview of GRASS GIS Benefits

The biggest advantage of GRASS GIS over other similar software is that it is open source and freely-available to users. It was originally developed by the US Army as a tool for environmental planning and land management. With the passage of time, the simple tool evolved into a multi-function software that offers a wide range of utilities useful for academic and scientific research institutes, government institutes, NGOs as well as commercial settings. The system is comprised of 350+ modules that allow users to render maps and images and manage location-based data.

It can also be used for vector and raster data, multispectral image processing and spatial data creation, storage and manipulation. It supports both a graphical user interface and command line syntax and can interface with various printers, digitizers, plotters and databases. The software supports workgroups using the concept of mapset/location and is able to share data over the Network File System. Teams can also keep locations on a central server with underlying mapsets and work simultaneously in the same project DB.

GRASS GIS offers powerful capabilities, including raster, 3D-raster (voxel), vector, DTM and point data analysis, image processing,  geocoding, visualization, map creation, geostatistics, temporal framework, erosion modeling, landscapestructure analysis, watershed analysis and solution transport. The software also supports various database interfaces, including SQLite, DBF, PostgreSQL, ODBC and MySQL. The latest release of the software by default manages attributes in SQLite format and features a full temporal framework.

If you are interested in GRASS GIS it could also be beneficial to examine other subcategories of Best Geographic Information Systems - GIS collected in our database of B2B software reviews.

It's crucial to keep in mind that hardly any service in the Geographic Information Systems - GIS category is going to be a perfect solution that can fulfill all the goals of all company types, sizes and industries. It may be a good idea to read a few GRASS GIS reviews first as specific solutions may perform well just in a very narrow set of applications or be prepared with a really specific type of industry in mind. Others can work with an idea of being easy and intuitive and consequently lack complicated features needed by more experienced users. You can also come across solutions that support a large group of users and give you a rich feature base, but this in most cases comes at a more expensive cost of such a service. Be certain that you're aware of your requirements so that you get a service that offers specifically the features you look for.
