OpenAtlas

Implement geopackage (.gpkg) import functionality to support the direct upload and processing of geometry data from these files.

All incoming data must use WGS 84 (EPSG:4326). During the import process, there should be an automated check to verify if the coordinates are within the valid range of -180 to 180 for longitude and -90 to 90 for latitude. If the file doesn't specify a CRS, the system should assume it's WGS 84 but flag it for a manual check if values look dodgy.

The data mapping table needs to be clear about what we are actually looking at. Every geometry must be assigned to a specific category:

• Place
• Feature
• Stratigraphic Unit
• Artifact

Additionally, the import table must show the link to the corresponding OpenAtlas ID or a Custom ID, similar to how the current place hierarchy import handles things. We need to see exactly where each geometry is landing in the system.
