GeoJSON Geometry Inspector

• Enter the displayed example values,or choose the local input files requested by the controls. Optional source files take precedence where labelled.
• Choose Inspect GeoJSON and inspect the complete result and any reported limitations.
• Use Download result and each companion download link to save complete outputs. Reset clears output and restores example controls.

Source text: {"type":"LineString","coordinates":[[4.35,50.85],[4.36,50.86]]}

• Inspect complete RFC7946 geometry,Feature or FeatureCollection structure,properties,foreign members,original paths,ordinary axis bounds and antimeridian-crossing segment counts. Longitude/latitude within±180/±90;legacy crs refuses. Declared bbox shape/ranges checked;this does not certify containment or minimal antimeridian envelopes. Numeric decimal spelling may normalize in binary64;source unsafe integers/nonfinite numbers refuse. Empty Point coordinates supported as an empty-geometry profile. Complete JSON at most20 MiB. Up to2,000geometry objects/20levels/20,000positions,consistent2D/3D,finite binary64 coordinates within±1e12 and safe integer tokens. Empty whole geometries/collections retained;nonempty lines need2positions,rings4with exact closure. No ring orientation,self-intersection,hole containment or topology certification. One text/file source up to1 MiB;strict UTF-8,40JSON levels/100,000values or20,000XML nodes/40levels. Complete output only;oversized results refuse. No network or coordinate reprojection;all processing stays in your browser.60-second worker limit.
• Complete outputs only. Unsupported or oversized input is refused. Follow the displayed job-specific bounds and format policies.
