The problem
GIS teams lose hours to datasets full of overlaps, gaps, spikes and self-intersections. The usual fix means an expensive desktop licence — or uploading sensitive survey data to someone else's server just to clean it.
Reaches Layer 2 & 3 — customer self-service plus recurring billing operations
What we built
- Accounts, log-in and subscription billing — monthly, yearly and lifetime plans
- Multi-format import: Shapefile, GeoJSON, KML and GPX, read directly in the browser
- 12+ topology checks — self-intersections, overlaps, gaps, spikes, tiny areas, unclosed rings, duplicate vertices
- Interactive map editing: drag vertices, add midpoints, split by cut line, merge adjacent polygons
- Full undo/redo history across every editing operation
- Convergent multi-pass batch auto-fix that resolves overlaps to near-zero residuals
- Clean export back out to Shapefile, GeoJSON or KML
