Sorry for the off topic noise everyone.

I have some ascii files dumped as the AAIGRID format from gdal. These are esri
ascii grids.

The format appears simple:
ncols        98
nrows        172
xllcorner    1044355.808370659710
yllcorner    10042832.567399607971
cellsize     91.442854747403
*then the z values are listed for each line*

Problem is I dont know which friggin way these go. I tried left to right
starting lower left and incrementing x and y. I end up with skewed data.

Does anyone know where I can get the specs on this format that explicitly
explain in thorough detail how its formated?

Thanks.
