webgeods: GeoJSON problems, laid out without the magic wand

Field notes

The homepage presents two focused workflows rather than a broad GIS software suite. Users upload GeoJSON, inspect invalid geometries or topology defects, and view the diagnosis on a map; the listed stack combines Python, R, and MapLibre. The site names specific failure modes—including overlaps, gaps, slivers, duplicates, and dangles—and distinguishes reporting from repair, leaving the user to choose whether and how to alter the data.
