FW: [Mapserver-users] Need Info and Help for a first test

[Vincent Schut]

Harato,

With the coordinates you specified, units should be meters, not DD. DD means 
decimal degrees, and these will never exceed 180. This means that you should 
also use a projection that is in meters, like some mercator projection (UTM 
etc.)
Unless your layer data files are in the same projection as the projection you 
want everything to show up, you will need to define a projection block in 
your mapfile to specify the final projection, and one in each layer block 
that has a different projection that the final one, so mapserver knows what 
to reproject from and to.
For more info about this you'd best take a serious look at the documentation 
sections on the mapserver internet pages. Sometimes it takes a while before 
you find what you need, but there is lots and lots of valuable info there, 
especially about these basic things.
