[postgis-users] Converting From MULTILINESTRINGM to MULTILINESTRING

[Bertand Revenaz]

Hi All,

I have been struggling with some dirty data from arcview, specifically a lot
of the shapefiles had a thrid dimension, but it conntained no useful data. I
am using this data with geoserver and it doesn't like multilinestringm
types. How would I go about stripping out the third dimension. is there a
way to do it in postgis or do I have to export all the geometries as text
and grep them?

Thanks,

Bert
