I have imported various shape files, all obtained from the geofabriks website, into QGIS using the 'PostGIS Shapefile Import/Export Manager'. A couple of them are throwing the error “Error: Operation on mixed SRID geometries”, on the below query.
I set the SRID during import, and have tried updating it using SET_SRID, st_transform, etc, but still get the error. Using ST_SRID to check the SRID returns 4326 (as expected).
Does anyone have any suggestions (I think I've tried everything on all the other questions about this)?
I also noticed that when adding these tables as a layer to QGIS, when zooming in a lot, the line covers the whole map (guessing this is related to the issue)
Files are from http://download.geofabrik.de/europe/great-britain/england.html (I'm having the issue only with Derbyshire, Nottinghamshire + Leicestershire, all others work as expected).
Could there be an issue with the shapefiles themselves?
Query - SELECT ST_CONTAINS(ST_ESTIMATEDEXTENT('tableName', 'geom'), ST_SetSRID(ST_MakePoint(lng,lat),4326)) as contains
Questions I've been looking at are:
- PostGIS Geometry Query returns "Error: Operation on mixed SRID geometries" only for certain values
- Operation on mixed SRID geometries
I've tried various methods of updating the SRID, all seemed to work, but the error persisted. I've tried setting the Point with ::geography::geometry, to force it to use SRID 4326.
