How to use this tool
- Enter the displayed example values,or choose the local input files requested by the controls. Optional source files take precedence where labelled.
- Choose Convert geometry 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.
Examples
Conversion: geojson-to-wkt
Source text: {"type":"LineString","coordinates":[[4.35,50.85],[4.36,50.86]]}
Empty geometry dimension: 2
Limitations
- Convert actual Point,MultiPoint,LineString,MultiLineString,Polygon,MultiPolygon and GeometryCollection representations between geometry-only GeoJSON and2D/Z WKT. No Feature/properties,bbox,foreign-member loss,SRID,M/ZM,curves or CRS-definition WKT. Mixed dimensions refuse. Empty whole types and empty multi-line/polygon components supported;EMPTY individual MultiPoint members refuse. GeoJSON has no explicit empty-dimension declaration;WKT source dimension is retained in companion report,and GeoJSON→WKT uses the explicit empty dimension. Complete WKT/GeoJSON at most10 MiB plus complete report. 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.
