OpenJUMP GIS
The extensible, Java-based open-source GIS for high-precision vector processing and spatial analysis.

The open-source standard for professional-grade spatial analysis and geodata management.
gvSIG Desktop is a high-performance, open-source Geographic Information System (GIS) built on a modular Java architecture, designed to manage complex spatial data with professional precision. As we move through 2026, gvSIG remains a critical alternative to proprietary GIS suites like ESRI ArcGIS, offering a robust environment for vector and raster data processing, sophisticated cartographic rendering, and database integration (PostGIS, Oracle, SQL Server). Its technical architecture is highly extensible via the 'Scripting Framework,' allowing developers to automate workflows using Python (Jython). The platform is distinguished by its adherence to Open Geospatial Consortium (OGC) standards, ensuring seamless interoperability with WMS, WFS, and WCS services. In the 2026 market, gvSIG positions itself as the lead-gen choice for public administrations, environmental agencies, and research institutions seeking to avoid vendor lock-in while maintaining enterprise-grade spatial modeling capabilities. Its ecosystem includes seamless synchronization with gvSIG Mobile and gvSIG Online, creating a unified full-stack geospatial workflow for field data collection and cloud-based distribution.
Integrated IDE for developing custom tools and automation scripts using Python (Jython) within the GIS environment.
Verified feedback from the global deployment network.
Post queries, share implementation strategies, and help other users.
A comprehensive library of hundreds of algorithms for spatial analysis, hydrology, and statistics.
Hardware-accelerated 3D engine for visualizing digital terrain models (DTM) and 3D vector data.
