We have for various reasons, needed to import coordinate data directly into the database, but are having some issues displaying it in the GIS client.

Here is the response, which is giving issues. See below.

These are polygons. Just add another “[” and “]” to the coordinates to make them multi-polygons and it will work.

Thanks Jan. That worked perfectly. I should have remembered this from before, as I think you have answered the same question before. :slight_smile:

The GML importer inserts “Polygon” into the “featuretype” field though, so it is not obvious. Should ideally be changed. The GIS app accepts both “Polygon” and “MultiPolygon”.

Yeah, well, I did not use the GML importer, because my geodata has non-unique names, and there is currently no way (which I know of) to get around this. So, I created SQL and imported this directly into the system. Postgresql claims the FeatureType is already “Polygon”, so it seems a bit strange that I would need to coerce the Polygons to MultiPolygons to get it to work?

Regards,

Jason

We decided back in the day that we only wanted to deal with points and multipolygons, so the GML importer accepts both polygon and MP coordinates but converts polygon coordinates to MP coordinates before inserting it in the db. The GIS app is relying on this and supports points and MP coordinates only (though both “Polygon” and “MultiPolygon” as featuretype). Which admittedly is not very alternative-importation friendly.
