Geospatial Loaders

The Geospatial category is experimental

Several geospatial formats return data in the form of lists of lng/lat encoded geometric objects.

Geospatial Category Loaders

Data Format

For geospatial formats that contain a single layer:

• category: string - gis
• schema?: Schema - Apache Arrow style schema
• data: * - Data is formatted according to options.gis.format
• format: string - The encoding of data layers, corresponds to options.gis.format.
• loaderMetadata?: object - Loader specific metadata, see documentation for each loader

For geospatial loaders that contain multiple layers:

• category: string - gis-layers
• layers: A map of layers keyed by layer names. Each layer is formatted according to options.gis.format
• loaderMetadata?: object - Top-level loader specific metadata, see documentation for each loader

For geospatial loaders that contain a single geometry:

• category: string - gis-geometry
• schema?: Schema - Apache Arrow style schema
• data: * - Data is formatted according to options.gis.format
• format: string - The encoding of data layers, corresponds to options.gis.format.

GeoJSON Conversion

Geospatial category data can be converted to GeoJSON (sometimes with a loss of information). Most geospatial applications can consume geojson.
