Check format of file.<br> ~~\|alt_msg=NA~~ ERROR 2333 - Reading rainfall grid file <filename> \|type=[[ERROR]] \|message_desc=This message indicates that the ~~file is not in the ESRI ASCII~~ grid ~~format. This format (usually has the extension .asc or .txt) and~~file is ~~a plain text file (~~not ~~binary) and can be opened~~ in ~~a text editor. At~~ the ~~top~~recognised offormats ~~the file, information on the size of the grid, the cell size and coordinates should be displayed. An example is~~which ~~below~~are:<br> '''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>▼ <u>[[VM_Export_to_ASC\| MapInfo with Vertical Mapper]]</u>▼ <u>[[Arc_Export_Raster_to_asc\|ArcMap]]</u>▼ <u>[[QGIS_Export_Raster_to_asc\|QGIS]]</u>▼ <br> Ensure that the <tt><font color="blue">Read GRID</font></tt> command is only used for gridded data. For GIS data in ESRI Shapefile or MapInfo MIF format, the <tt><font color="blue">Read GIS</font></tt> command is required instead. ▲\|suggestions=Open the file in a text editor to ensure that the file is in the correct format.
