[Gdal-dev] gdalinfo

[Dobmeyer, Todd]

That is the problem. I do not know if the tif files start at the very
top of the globe, or if they are at say 80 or 85 degrees North. If I
could figure this out, how would I use gdal_translate and gdal_warp to
make a .tfw file? Thanks.

Do you know the projection and coordinates? If so you can use
gdal_translate and gdal_warp to generate one but you have to know the
corner points of your image.

	Did you create your own tfw file or find one? I do not seem to
have any
	tfw files with my tif files. This is why I cannot find the
information I
	want? Thanks again!

	Does the image come with a tfw? Your output suggests there's no
projection associated with your tif.

	 

	Here's what my gdalinfo looks like on GeoTiff's I create:

	 

	Driver: GTiff/GeoTIFF
	Size is 1039, 3628
	Coordinate System is:
	GEOGCS["WGS 84",
	    DATUM["WGS_1984",
	        SPHEROID["WGS 84",6378137,298.2572235629972,
	            AUTHORITY["EPSG","7030"]],
	        AUTHORITY["EPSG","6326"]],
	    PRIMEM["Greenwich",0],
	    UNIT["degree (supplier to define
representation)",0.01745329251994328],
	    AUTHORITY["EPSG","4326"]]
	Origin = (-105.220222,40.261786)
	Pixel Size = (0.00020000,-0.00020000)
	Corner Coordinates:
	Upper Left  (-105.2202222,  40.2617861) (105d13'12.80"W,

	Lower Left  (-105.2202222,  39.5361861) (105d13'12.80"W,

	Center      (-105.1163222,  39.8989861) (105d 6'58.76"W,
39d53'56.35"N)
	Band 1 Block=1039x7 Type=Byte, ColorInterp=Red
	Band 2 Block=1039x7 Type=Byte, ColorInterp=Green
	Band 3 Block=1039x7 Type=Byte, ColorInterp=Blue
