Vector Data: Native Coordinate Reference System Not Preserved

When ingesting vector datasets (WFS, OGC API Features), the Connector requests data from the source service in WGS84 (EPSG:4326) coordinates when possible. If the source service supports WGS84, it performs the coordinate transformation before delivering the data to the Connector.

As a result, the ingested data contains WGS84 coordinates, and the original coordinate reference system of the source dataset is not preserved. The geom_native and crs_native columns in the ingested table will be empty for these datasets.

This applies to most WFS and OGC API Features data sources, as the majority of vector services support WGS84. Datasets whose native coordinate reference system is already WGS84 are not affected.

What works correctly:

• The geom_wgs84 column contains accurate WGS84 geometry
• H3 spatial indices are computed correctly from the WGS84 geometry
• All other enrichment columns (centroids, geometry type) are correct
• Raster data sources (WMS, WMTS, WCS, OGC API Maps, OGC API Tiles, OGC API Coverages) are not affected by this limitation
