[maplab-users] Projection problem in Maplab with MSW4

[charley cheng]

Thanks Daniel,
 
You are right, after I add ellips, the maplab does not crash, but I still could not see the any map. Is it possible my OGR connection to mapinfo tab file not corrected? Any suggestion?
 
When I use info tool in preview  click on the blank map , the error message is " Fatal error [MapServer Error] msProcessProjection(),  projection not named in C:\ms4w\apps\maplab-2.1\htdocs\common\wraper\map_session.php on line 841
 
Thanks 
 
Charlie

I believe you need to specify the ellipsoid parameter as well when you 
specify a latlong projection. Try:

PROJECTION
"proj=latlong"
"ellps=WGS84
END
