Line 3: \|alt_msg=NA \|type=[[ERROR]] \|message_desc=This indicates that the ESRI ascii grid file does not contain a valid grid, or the file is incomplete. This file 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> ~~\|message_desc=~~ <tt> ~~\|suggestions=~~ ncols 2284<br> \|discussion_page=* [[Talk:TUFLOW Message 2333\|Discuss Message 2333]]▼ nrows 3916<br> xllcorner 0.0<br> yllcorner 0.0<br> 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. \|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:<br> [[VM_Export_to_ASC\| MapInfo with Vertical Mapper]] [[Arc_Export_Raster_to_asc\|ArcMap]] [[QGIS_Export_Raster_to_asc\|QGIS]] ▲\|discussion_page= [[Talk:TUFLOW Message ~~2333~~2334\|Discuss Message ~~2333~~2334]] \|link3='' \|link4=''
