I am using orthographic projection to generate globe layer
Its showing globe but sometimes half of it or some part.
Also I am not able to rotate or pan through the globe.
In openlayers I am using var options =
{
controls: [],
restrictedExtent: extent,
numZoomLevels: 10,
maxResolution:0.49990340909090999,
projection:"EPSG:9840"
}
and my mapfile is as follows:-
EXTENT -180 -90 180 90
UNITS DD
SIZE 550 450
PROJECTION
"proj=ortho"
"ellps=WGS84"
"lat_0=51.0000"
"lon_0=0.0000"
"x_0=0.00"
"y_0=0.00"
END
#World_Background
LAYER
NAME "background1"
STATUS DEFAULT
PROJECTION
"proj=latlong"
END
TYPE RASTER
DATA "wsiearth.tif"
TEMPLATE "ttt.html"
END
I am confused this is due to the extent I have set or projection definition
set in mapfile.
Please help as this is very urgent and I have a deadline to meet.
Regards
Kusum
