Hi Anders,BIL is a common elevation data format (just rows and columns of values) . Proper interpretation of such raw data requires additional information (Metadata) about the file. The BLW file (BIL World file) is one of several such files usually provided with data in the BIL format.Here is an example, with descriptions of each entry:[table border=0][tr][td width=130" align="right]0.00833333333333[/td][td width=15] [/td][td width=400] x dimension of a pixel (decimal degrees)[/td][/tr][tr][td width=130" align="right] 0.00000000000000[/td][td width=15] [/td][td width=400]rotation term[/td][/tr][tr][td width=130" align="right] 0.00000000000000[/td][td width=15] [/td][td width=400]rotation term[/td][/tr][tr][td width=130" align="right] -0.00833333333333[/td][td width=15] [/td][td width=400]negative y dimension of a pixel (decimal degrees)[/td][/tr][tr][td width=130" align="right]-99.99583333333334[/td][td width=15] [/td][td width=400]longitude of the center of the upper-left pixel[/td][/tr][tr][td width=130" align="right]39.99583333333333[/td][td width=15] [/td][td width=400]latitude of the center of the upper-left pixel[/td][/tr][/table]Cheers,Steve
