What OpenJUMP GIS is

OpenJUMP GIS is a free, open-source desktop geographic information system written in Java and maintained by volunteers. It runs on Linux, macOS, and Windows, and is designed for working with geometry and attribute data. The current version reads and writes shapefiles and simple GML files; plugins can add support for other vector formats. OpenJUMP can read from spatial databases, write to PostGIS, and work with WFS and WMS web services. For map work, it offers styling tools and lets users export a map view to SVG. Its vector analysis tools cover topology and overlay operations, while raster tools are available through extensions. The plugin ecosystem also includes database and format readers, printing, quality checks, charts, and GIS analysis tools. Extensions are added by placing a plugin JAR in the application's lib/ext folder and restarting OpenJUMP. The site lists version 2.4.0, dated January 15, 2025, as the latest release. Users can seek help through a forum or mailing list; developers have a separate mailing list, and bug reports and feature requests go through trackers. The project notes that OpenJUMP does not include every feature available in proprietary GIS software.

Who it suits

OpenJUMP suits desktop users in fields such as agriculture, government, nonprofits, and science or research who need to edit spatial data or perform vector analysis. Developers can also use it, with a separate mailing list and plugin extensions for additional capabilities.
