Hi,

I have a problem with obtaining geotiff map's coordinates. I would like to get coordinates for upper left and lower right corner. Tool called listgeo (ftp://ftp.remotesensing.org/geotiff/libgeotiff/listgeo_GUI.zip) returns good coordinates for my map, but when I try to get these coordinates using geotiffs java libs usually I get error: "GeoKey directory does not exist" (using http://geotools.codehaus.org libs) or I get empty values for interesting geotags (using http://sourceforge.net/projects/geotiff-jai or http://sourceforge.net/projects/xtiff-jai).
Can you tell me how can I retrieve this information using java libs? Google doesn't say anything interesting about this

BTW: Map is in UTM zone 34 and compressed LZW.
