Learn what a DXF file is, how DXF differs from DWG, why CRS matters in GIS, and how to open or convert CAD drawings to GeoJSON, KML, or Shapefile.
Learn to validate GeoJSON for RFC 7946 with the free online validator. Catch geometry, coordinate, and structural errors before publishing GIS data.
Preview Shapefile, GeoJSON, KML, PMTiles, and other geospatial files inside VS Code without opening a full desktop GIS.
GeoJSON vs GeoPackage compared: size, portability, multi-layer support, and when to convert for web maps or GIS workflows.
GeoJSON vs Shapefile compared for GIS data exchange: choose GeoJSON for web maps and APIs or Shapefile for legacy GIS, government portals, and CRS flexibility.
GML vs GeoJSON compared for GIS: keep GML for OGC/WFS schemas or choose GeoJSON for web maps, APIs, and fast browser inspection.
GPX vs GeoJSON compared: keep GPX for GPS tracks, routes, and waypoints; choose GeoJSON for web maps, APIs, and flexible GIS properties.
Convert DWG to GeoJSON step-by-step in your browser. Preview the layer, export GeoJSON, and troubleshoot common DWG conversion issues.
KML vs GeoJSON explained: compatibility, typical use cases, and the simplest way to open and convert files for modern web mapping.
What is GeoJSON and why is it common in web maps and APIs? Learn the file structure, geometry types, RFC 7946 rules, limitations, and how to view or validate it online.
Learn what GML is, how it compares to GeoJSON, common use cases, and how to open and visualize GML files using GeoDataViewer.
