TUFLOW Message
ERROR 2321 - Insufficient header information in ASCII grid file. Check format of file.
Alternate Message
NA
Message Type
ERROR
Description
This message indicates that the file is not in the ESRI ASCII grid format. This format (usually has the extension .asc or .txt) and is a plain text file (not binary) and can be opened in a text editor. At the top of the file, information on the size of the grid, the cell size and coordinates should be displayed. An example is below:
ncols 2284
nrows 3916
xllcorner 0.0
yllcorner 0.0
cellsize 5.0
NODATA_value -9999
After the header information should follow the ncols x nrows of data. If the file is not in a similar format to the above, the file is most likely not in the correct format.
Suggestions
Open the file in a text editor to ensure that the file is in the correct format. If not, this may need to be re-exported from your GIS package. Instructions for doing so in command GIS packages are below:
