Hi,
thanks for the ideas. Have tried this and here is what I got back from
gdalinfo (I couldnt seem to get ogrinfo to run on my tif files):
D:\ms4w\tools\gdal-ogr>gdalinfo
D:\opendata\minisc_gb\MiniScale\data\miniscaleno
grid.tif
Warning 1: TIFFFetchNormalTag:Incompatible type for "RichTIFFIPTC"; tag
ignored
Driver: GTiff/GeoTIFF
Files: D:\opendata\minisc_gb\MiniScale\data\miniscalenogrid.tif
Size is 7000, 13000
Coordinate System is `'
Origin = (0.000000000000000,1300000.000000000000000)
Pixel Size = (100.000000000000000,-100.000000000000000)
Metadata:
TIFFTAG_SOFTWARE=Adobe Photoshop CS4 Macintosh
TIFFTAG_DATETIME=2009:12:04 12:52:34
TIFFTAG_XRESOLUTION=254
TIFFTAG_YRESOLUTION=254
TIFFTAG_RESOLUTIONUNIT=2 (pixels/inch)
Image Structure Metadata:
COMPRESSION=LZW
INTERLEAVE=PIXEL
Corner Coordinates:
Upper Left ( 0.000, 1300000.000)
Lower Left ( 0.0000000, 0.0000000)
Upper Right ( 700000.000, 1300000.000)
Lower Right ( 700000.000, 0.000)
Center ( 350000.000, 650000.000)
Band 1 Block=7000x12 Type=Byte, ColorInterp=Red
Band 2 Block=7000x12 Type=Byte, ColorInterp=Green
Band 3 Block=7000x12 Type=Byte, ColorInterp=Blue
I took all of the stuff out of the map file with the exception of the extent
and ran shp2img and it runs without any problem, generating a blank png
image. I guess I need to add the correct extent information to get the image
to display?
Cheers
Carl
