MapServer and PostGIS GEOMETRY type

[Jan Hartmann]

Hi Jacob,

The Mapfile Reference Manual, chapter Layer says 
(http://mapserver.gis.umn.edu/docs/reference/mapfile/layer)

------------------------------------------------------------

TYPE [point|line|polygon|circle|annotation|raster|query|chart]

     Specifies how the data should be drawn. Need not be the same as the 
shapefile type. For example, a polygon shapefile may be drawn as a point 
layer, but a point shapefile may not be drawn as a polygon layer.Common 
sense rules.

------------------------------------------------------------

You probably just have to try it out on your data.
