Writing to spatialite causes crs mismatch #8

Closed AsgerPetersen closed 9 years ago

AsgerPetersen commented 9 years ago

It seems that geometries are written to spatialite in their native coordinate reference system (for instance UTM), but in spatialite they are assigned wgs84

Thanks for the bug report!

I reproduced the problem (with spiderosm_portland.py) and will look into it.

Fixed. (As of v0.4.0) Note: this requires use of the new spiderosm SRS object:

spatial reference system

srs = spiderosm.spatialref.SRS(
        url="http://www.spatialreference.org/ref/epsg/wgs-84-utm-zone-10n/",
        units='meters',
        spatialite_srid=spiderosm.config.settings.get('spatialite_srid'),
        postgis_srid=spiderosm.config.settings.get('postgis_srid')
        )
spiderosm.log.info('srs info:\n%s', srs.info()

... db = spiderosm.spatialite.Slite(sqlite_fn, srs=srs)

See spiderosm_berkeley.py and README.md for details.
