Hello, I've been wrestling around with 3D and have gotten my table/geom to x,y,z so that
SELECT ST_AsEwkt(the_geom) FROM <table> LIMIT 1; returns "MULTIPOLYGON(((611630.148961496 690526.520745486 0,611619.960661661 690507.134957485 0, 611545.79119058 690545.364867903 0,611556.435198162 690565.595798574 0,611630.148961496 690526.520745486 0)))" In another column are the values I'd like to use for Z, or calculate Z from. And then brain death. What sort of statement would I be using to update the Z part of the XYZ, as a calculated result from another column. Any help or suggestions greatly appreciated. Chris
