Hi,
I would appreciate if you could have a try with
"gdalwarp -of vrt -t_srs "EPSG:3857" sat.tif sat_3857.vrt"

shp2img creates an empty blank image with a mapfile like this:
MAP
NAME "map"
WEB
METADATA
"wms_title" "WMS mapserver"
"wms_srs" "EPSG:4326 EPSG:3021 EPSG:9999 EPSG:3006
EPSG:900913"
"wms_extent" "1225000 6130000 1910000 7675000"
"wms_enable_request" "*"
"wfs_enable_request" "*"
END
END
PROJECTION
"init=epsg:4326"
END
EXTENT 15 60 30 68
SIZE 200 200
LAYER
NAME "sat"
DATA "/data/temp/Jesper/sat.tif"
TYPE RASTER
STATUS DEFAULT
METADATA
"wms_title" "sat"
END
END
The output from shp2img looks like this:
$ shp2img -m ttt.map -o /data/temp/Jesper/ttt.png -all_debug 5
msLoadMap(): 0.003s
msDrawMap(): rendering using outputformat named png (AGG/PNG).

msDrawRasterLayerGDAL(): source raster PL (14.962,10645.462) for dst PL (0,0).
msDrawRasterLayerGDAL(): red,green,blue,alpha bands = 1,2,3,4
msDrawMap(): Layer 0 (sat), 0.011s
msDrawMap(): Drawing Label Cache, 0.000s

freeLayer(): freeing layer at 0x1d1d080.
freeLayer(): freeing layer at 0x1d1e1b0.
shp2img total time: 0.017s
If I add:
PROJECTION
"init=epsg:4326"
END
EXTENT 17.0473154408269387 62.1606759790530177 27.5792082876237146
66.7744046276809797
shp2img outputs:
msLoadMap(): 0.003s
msDrawMap(): rendering using outputformat named png (AGG/PNG).
msDrawRasterLayerLow(sat): entering.
msDrawRasterLayerGDAL(): Entering transform.
msDrawRasterLayerGDAL(): src=0,0,10474,10717, dst=27,63,140,61
msDrawRasterLayerGDAL(): source raster PL (-49.554,-33.774) for dst PL (27,63).
msDrawRasterLayerGDAL(): red,green,blue,alpha bands = 1,2,3,4

freeLayer(): freeing layer at 0x245c080.
freeLayer(): freeing layer at 0x245d430.
shp2img total time: 0.033s
Then the image is shown in ttt.png but is not in the correct place and not
rotated correctly.
Any help or ideas are appreciated!
Thanks
Jesper

<jmcke...@gatewaygeomatics.com<mailto:jmcke...@gatewaygeomatics.com>>:
I'm curious what happens when you try to generate a map image from the
commandline: shp2img -m test.map -o ttt.png -all_debug 5
