[MS4W-Users] How to mention multiple projections in MapServer MAPFILE?

[Stephen Woodbridge]

Shiva,

To be explicit, mapserver does not support a layer where each geometry 
has its own projection. You will need to separate the data into multiple 
tables where all geometries in any given table are the same projection.
