[FWTools] Convert ASCII file to Arc/Info ASCII Grid

[Matt Wilkie]

Hi Cecília,

The aaigrid format is arcinfo's GRIDASCII format, which is not the same 
as arcinfo GRIDFLOAT (.flt).

Running gdalinfo on a .flt generated from ArcCatalog RasterToFloat 
(v9.3.1) reports "Driver: EHdr/ESRI .hdr Labelled" -- 
http://www.gdal.org/frmt_various.html#EHdr

However in my tests here I was not able to read a gdal-generated EHdr 
image with FloatToRaster. It complained about the BYTEORDER parameter 
being missing from the .hdr file. Adding that by hand did not change the 
error. Arcinfo Workstation may not be as picky(?)

best regards,

matt wilkie
