Description
Raised when reading the header of an .asc or .flt grid file fails. This occurs when a required header field is missing (NCOLS, NROWS, XLLCENTER/XLLCORNER, YLLCENTER/YLLCORNER, or CELLSIZE).
Suggestions
Open the file and check that all required header fields are present and correctly formatted. For .flt files check the accompanying .hdr file.
