R: [Mapserver-users] projection - UTM and geographic

[Ballini Yvain]

You have to give a precision about your zone, for example zone = 32, for the longitudes between + 6° and +12°, zone = 33 for the longitudes between +12° and +18°...like this:

PROJECTION
  "proj=utm"
  "ellps=WGS84"
  "datum=WGS84"
  "zone=32"
  "north"
END 

Then the EXTENT gives you the coordinates Xmin Ymin Xmax Ymax with this rule:
Y = 0 at the equator line
X = 500000 (meters) at the longitude +9° for the zone UTM 32, or at the longitude +15° for the zone UTM 33...
You should control that the features you want to see are in this range of coordinates.

Regards,

Yvain.

Oggetto: [Mapserver-users] projection - UTM and geographic

I know this question hs been asked many times, but I can't seeme to find the solution.

I ahve a shape file that is in geographics (i.e. WGS84 lat/lon). I wish to display the shape file in UTM m. I tried putting the projection definition but the map does not show. My mouse coordinates (within jBox) are expressed in UTM m, but map is not dispalyed.

PROJECTION
    "proj=utm"
    "datum=WGS84"
  END

I also have -

EXTENT 111000 592500 279600 711000
UNITS METERS

Any ideas?

Thanks
