== Gridded Data ==
Gridded (raster) data is outputted in the ESRI ASCII grid format. This is plain text format and is very widely recognised and used by a variety of GIS software including ArcGIS (requires Spatial Analyst), QGIS, and MapInfo (requires Vertical Mapper or Encom Discover). This is specified with the flag '''-asc'''.<br>
 
The TUFLOW to GIS utility uses the same approach as TUFLOW for interpolating a raster.  That is, each cell is split into 4 triangles with a common vertex at the cell centre. An ASCII grid output directly from TUFLOW will use the calculated value at the cell centre (ZC). For an ASCII grid output using the TUFLOW to GIS utility, the centre used is the average of the corners.  For this reason, the grids will not be exactly the same.
