[Mapserver-users] Is it mandatory to use projection?

[Chip Hankley]

Rémi,

Specifying a projection in MapServer is NOT mandatory. The only time you need to do this is when you are combining data sets from a variety of projections, or you want to show the data in a different projection (perhaps your data is geographic, and you want to display it in albers).

The "default" projection is the projection of your data... basically as long as all of your layers use the same projection. It IS important, however, to make sure you specify the correct UNITS in your mapfile, as this directly affects the SCALE settings in MapServer.
