I want to convert a geoTIFF file into ESRI Grid Format (Arcinfo Binary Grid)using QGIS --Raster--Conversion---translate tool but I get a error message saying "creation parameters not defined". What is this and how to proceed next?
AIG -- Arc/Info Binary Grid Supported by GDAL for read access.
Settings -> Options -> GDAL tell you the same.
So you are out of luck trying to write to that format. If you need to, you have to do the conversion with ESRI software.
