Steve,

Good point, I did have the extent in meters but that did not work.

Should these work?
EXTENT -20026376 -20048966 20026376 20048966

Thanks

Ian

How are you setting an extent? The default extent you're defining is in lat/lon.

Steve,



The map file below draws a non Mercator projection and if the epsg:4326 line is uncommented then the map is blank.



This is on a windows machine using Mapserver 7.0.7 from MS4W 3.2.6.



Any ideas?



Thanks



Ian

Should be straight forward. In the natural earth layers you'd have:



PROJECTION

    "init=epsg:4326" # geographic

END



and at the MAP level you'd have:



  PROJECTION

    "init=epsg:3857" # web mercator

  END

Hello,



We have used different projections previously but cannot get them to work at the moment.



All the examples we can find online look ok but do not make any difference to the generated map.



A way of projecting the Natural Earth vector country outlines as Mercator would be a perfect example.



Adding  CONFIG "PROJ_DEBUG" "ON" does not appear to generate any output.



Thanks
