Hi Frank,
Thanks for responding. I have tried the following,
gdal_translate -ot Float32 -of AAIGrid src.tif dst.asc
Only to get an AAIGrid in Int16 format....??
Bill,
I see that by default floating point values in the AAIGRID CreateCopy
code are written as "%6.20g" which just produces an integer representation
if the values are integers. I tried this which did produce floating point
output values since the original pixels were rescaled in the 0.0 to 1.0 range.
gdal_translate utm.tif out.grd -of AAIGRID -ot Float32 -scale 0 255 0 1
(the exceptions were still the integer values of 0 and 1)
I see you can manually control the formatting with the DECIMAL_PRECISION
creation option.
eg.
gdal_translate utm.tif out.grd -of AAIGRID -ot Float32 -co DECIMAL_PRECISION=3
Best regards,
