however is required without needing to actually map the data out. It is more work overall, but if your MapFiles don’t change often, it’s usually a one time setup thing.<o:p></o:p></span></p>

mapfiles slightly, making use of GROUP LAYERs to group almost identical LAYERs together, the only difference in the LAYERs being MAX & MINSCALEDENOM and the DATA request string to our PostGIS database – hitting a generalised version of the geometry at smaller
scales.<o:p></o:p></span></p>
