ArcGIS Online
The premier cloud-based GIS platform for mapping, spatial analysis, and location-based data intelligence.

Free and Open Source Spatial without Compromise

QGIS is a free and open-source Geographic Information System (GIS) providing a wide array of tools for spatial data visualization, analysis, and editing. It supports numerous vector, raster, and database formats, enabling users to create maps, perform spatial analysis, and manage geospatial data. Its architecture is built on a plugin framework, allowing for extensive customization and extension of its core functionalities. QGIS is valuable for researchers, policymakers, and businesses needing geospatial data analysis for environmental monitoring, urban planning, resource management, and location-based services. Its open-source nature fosters community-driven development and ensures accessibility for all users, regardless of their budget.
