ArcGIS Desktop is a commercially available GIS from Esri. ArcGIS Desktop allows users to create, analyze, manage, and share geographic information through the creations of maps, spatial analysis, and data management. You can import multiple data formats and use analytical tools and workflows to identify spatial patterns, trends, and non-obvious relationships.
ArcGIS Pro is a commercially available GIS from Esri. ArcGIS Pro supports data visualization, advanced analysis, and authoritative data maintenance in 2D, 3D, and 4D. It supports data sharing across a suite of ArcGIS products such as ArcGIS Online and ArcGIS Enterprise, and enables users to work across the ArcGIS system through Web GIS.
GRASS GIS is an open source (free) software. GRASS GIS offers raster, vector, and geospatial processing engines in an integrated software suite. It includes tools for terrain and ecosystem modeling, hydrology, visualization of raster and vector data, management and analysis of geospatial data, and the processing of satellite and aerial imagery. It comes with a temporal framework for advanced time series processing and a Python API for rapid geospatial programming. GRASS GIS has been optimized for performance and large geospatial data analysis.
gvSIG is a free and open source (free) software. gvSIG interoperable GIS used by thousands of users worldwide. It is easy to work in a variety of formats with gvSIG Desktop, vector and raster files, databases and remote services. There are tools to analyze and manage your geographic information.
QGIS is an open source (free) software. QGIS is a desktop geographic information system application that supports viewing, editing, printing, and analysis of geospatial data. It runs on Linux, Unix, Mac OSX, Windows and Android and supports numerous vector, raster, and database formats and functionalities.
WhiteboxTools is an open source (free) software. WhiteboxTools can be used to perform common geographical information systems (GIS) analysis operations, remote sensing, and image processing tasks. WhiteboxTools also contains advanced tooling for spatial hydrological analysis and LiDAR data processing. WhiteboxTools is not a cartographic or spatial data visualization package; instead it is meant to serve as an analytical back-end for other data visualization software, like QGIS and ArcGIS.
