|alt_msg=ERROR 2333 - Insufficient header information in ASCII grid file. Check format of file.<br>
ERROR 2333 - Reading rainfall grid file <filename>
|type=[[ERROR]]
|message_desc=This message indicates that the
'''ESRI ASCII grid ''' - 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:<br>
<tt>
ncols 2284<br>
Line 11 ⟶ 13:
cellsize 5.0<br>
NODATA_value -9999<br></tt>
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.<br>
'''BINARY grids (.flt format)''' - this format is a binary version of the above .asc. It is comprised of two files .hdr which is plain text and contains the information listed above and .flt which contains the grid data.
|suggestions=Open the .asc or .hdr 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:<br>
*[[VM_Export_to_ASC| MapInfo with Vertical Mapper]]
*[[Arc_Export_Raster_to_asc|ArcMap]]
*[[QGIS_Export_Raster_to_asc|QGIS]]
<br>
Ensure that the "<tt>Read GRID</tt>" command is only used for gridded data. For GIS data in ESRI Shapefile or MapInfo MIF format, the "<tt>Read GIS</tt>" command is required instead.
