PixelOkayPixelOkayDraw, inspect and refine GeoJSON features with clear validation and complete control over your data.
Draw geographic features, edit coordinates and arbitrary JSON properties, and validate topological warnings before exporting a portable .geojson file.
Points, paths, areas and complete FeatureCollections.
Edit vertex positions, feature data and document JSON.
Keep a fully local file with its original metadata.
Create and edit GeoJSON points, lines and polygons on a local map, inspect structural and topology warnings, then export the changed data and a separate validation report.
Add a point and a polygon to a small WGS 84 dataset, inspect coordinate and ring warnings, then export the edited collection and validation report separately.
Supports WGS 84 longitude/latitude and RFC 7946 geometry types through imported JSON. Direct map drawing is limited to Point, LineString and Polygon. It does not reproject coordinates or guarantee GIS topology. Large-ring intersection checks are bounded; antimeridian and polar geometry need review. Input is capped at 12 MiB, 10,000 features and 200,000 positions. The bundled Natural Earth outline is coarse and not a street map.
No. It edits GeoJSON coordinates but does not reproject them.
No. Checks are bounded and do not establish complete GIS topology validity.
