[postgis-users] Invalid geometry when using select AsText

[rdelisabeth]

Hey Ben, thanks for the quick reply.

This is a piece of the geometry:

"MULTIPOLYGON(((-203203.329774775 921205.762417328,-201414.754122524
920564.899066353,….etc etc etc ……..,-263950.345631436
1215368.70793936,-263772.821121782 1216068.78335908,-263784.403196605
1216749.98205891,-263958.177279213 1216452.48684392)))"

These are the values when I query AsText from the original data, and it
represents a piece of norway.

Does this mean anything to you? I will try the 32630 and get back to you.
