[mapserver-users] What is the default coordinate system used in MapServer (if no projection is defined)?

[Basques, Bob (CI-StPaul)]

I had an extent of 0 0 360 120  (units inches, 10ftx30ft)

Anyway, I think I tried zooming in to 50 50 80 80 and the "80" values seem to have been the problem.  I can send the actual link tomorrow if you want I have it in browser cache at the other desk.

I set the Map projection to 4326 and it all works fine.  Must be the two 80s without one being a negative as you described.  And yes I was using a CGI.

MapServer has no default, it’s just uses a simple Cartesian coordinate system. HOWEVER, the CGI does have some hooks that tries to auto-detect lat/lon coordinates and automatically convert them to what’s set in the MAP’s projection block. I believe that only kicks in if there is a projection block defined.

How’d you trigger the message?

All,

So I was trying to just display some data without a coordinate system assigned.  And I ended up eventually getting a LAT/LON (out of range) error.  Once I set the projection in the MAP block to something resembling a XY projection, all was well.

I suspect that LAT/LON is the default?  Is there a way to do something other than what I did to use simple Cartesian coordinates?
