Hi,<BR>
<BR>
The PostGIS document says the dimension number can be 2, 3, 4.<BR>2 is for 2D like Point(x,y).<BR>
<BR>
If I want to create a table for pointm (x,y,m), what number should be used? 2, or 3?<BR>
If I want to create a table for point (x,y,z), what dimension number should be used? 3?<BR>
<BR>Thanks,<BR>
