OpenOrienteering

OpenOrienteering is an open-source project dedicated to producing professional-grade cartographic tools specifically for the sport of orienteering. Its flagship offering, OpenOrienteering Mapper, supplies course setters, mappers, and national federation cartographers with a full desktop environment for surveying, drawing, and symbolizing IOF-compliant sprint, forest, and ski-orienteering maps. The program imports base data from drones, LiDAR, or government DEM files, then layers vegetation boundaries, contour lines, rock faces, and man-made features using the standardized ISOM 2017/ISSOM symbol sets. Field-work is accelerated through mobile templates and GPS tethering, while desktop finishing provides curve smoothing, color calibration, and overprint preview so that final PDFs or OCAD files can be sent directly to offset printers or course-setting software. Clubs rely on the same package to update existing maps after storm damage or urban development, and event organizers use its georeferenced exports to generate quick-print editions for local meets. Because the codebase is GPL-licensed, universities also embed it in GIS curricula to teach thematic cartography without proprietary restrictions. OpenOrienteering Mapper is available for free on get.nero.com; the single package is delivered through trusted Windows sources such as winget, always installs the newest upstream build, and can be pulled in bulk alongside other applications.
