[mapserver-users] On the fly Projection

[Sowmya Tiramdasu]

Hi Jeff, 

  Thanks for the references you provided . I gave the output projections
under the MAP section and the LAYER Projection under the layer section. But
I am not sure what is the error. The projection is not happening correctly.
I do not see any specific errors in the log file also. 

Below are the details of my two different shape files. I want the
SBET_Trajectory_source to be projected in to the Photogrammetric_point's
projection.

The projections I mentioned in my mapfile are : 

The output projection : PROJECTION
	"proj=utm"
	"zone=17"
	"ellps=WGS84"
	"datum=WGS84"
	"units=m"
	"no_defs"
END

SBET_Trajectory_Source projection : PROJECTION
			"proj=longlat"
			"ellps=GRS80"
			"datum=NAD83"
			"no_defs"
	END

--------------------------------------------------------------

Can you identify where I am going wrong ?  I am kind of stuck , don't have
any clues why it is not working. Thanks again for all your time and patience
in helping me. 

Thanks, 
Sowmya.

Hello Sowmya,

A really helpful site for searching for projections and then different
syntax examples for them is: http://spatialreference.org

Yours might be here: http://spatialreference.org/ref/sr-org/15/

Have fun!
