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.

Hi List,
For a particular client I have to translate a lot of MapInfo files into
PostGIS. Some files may contain some different geometries, which ogr2ogr
doesn't like. So I force the geometry type to "GEOMETRY" (-nlt
GEOMETRY). It translates fine, and seems to draw fine in MapServer. But
how does MapServer really deal with it?
If I have a polygon layer, and point it to a PostGIS table that contains
objects of the type "GEOMETRY", does it simply ignore anything that is
not a polygon? What about the results of attribute queries? Would those
be filtered on the geometry type of the layer?
I can avoid using "GEOMETRY type" by translating the files in FME, but
I'd prefer to recommend an Open Source solution.
Regards,
Jacob
