[gdal-dev] "tolerance condition error" on reprojecting natural earth data to webmercator (3857)

[Adam Akhtar]

Sorry for the slow reply Even,

I just tried this now and it seems to have worked. Thank you very much for
you help on this matter.

For posterity and other's benefit I modified my original command to include

-clipsrc -180.1 -85.0511 180.1 85.0511

i.e.

OGR_ENABLE_PARTIAL_REPROJECTION=true ogr2ogr -unsetFieldWidth -t_srs
EPSG:3857 -clipsrc -180.1 -85.0511 180.1 85.0511 -nlt PROMOTE_TO_MULTI -f
PostgreSQL PG:"dbname='ogr' host='localhost' port='5432' user='myusername
password='redacted'" ne_10m_ocean.shp

Thanks again

Adam
