GeoJSON

Use this skill for practical GeoJSON inspection and validation.

This skill focuses on safe read-only analysis of GeoJSON structure and coordinates. For deterministic GIS conversion, reprojection, clipping, or raster/vector processing on files, hand off to qgis.

What This Skill Does

• Validate whether a JSON file or payload is plausible GeoJSON.
• Summarize top-level type, feature count, geometry types, and bbox.
• Flag obvious coordinate-range issues for longitude/latitude style data.
• Explain common GeoJSON mistakes such as malformed FeatureCollection, missing geometry, or wrong coordinate nesting.
• Recommend when EPSG:4326 assumptions are safe and when CRS clarification is required.
