Created page with "=Introduction= MapInfo will be used to import the check files and view the final elevations in the 2D model. =Method= With the <tt>Write Check Files </tt></..."

New page
=Introduction=
MapInfo will be used to import the check files and view the final elevations in the 2D model.
=Method=
With the <tt>Write Check Files </tt> command specified, TUFLOW will output the elevations in the model in two formats. The elevations at the cells are contained in a point layer, this file is named '''M01_5m_002_zpt_check.mif''' and is located in the '''TUFLOW\check\2d\''' folder. Since the TUFLOW model is rotated (not north-south aligned). This file contains the exact elevations in the model. However, this not so easy to visualise and TUFLOW also outputs a raster (gridded) dataset in the ESRI ascii format. This can be viewed easily in most GIS packages including MapInfo.
<ol>
<li>Open the ''Import Dialogue'' by selecting ''Vertical Mapper >> Create Grid >> Import Grid...''</li>
<li>Select ''Add...'' and then navigate to the '''TUFLOW\Check\2D\''' directory and select the '''M01_5m_002_DEM_Z.asc'''.</li>
<li>When prompted, select the projection as Universal Transverse Mercator (WGS 84) and select the UTM Zone 60 Southern Hemisphere. 
'''Tip:''' If importing multiple grids ensure you check the ''Use for all imports of similar type'' checkbox, as per the image below (otherwise you will be prompted for each grid).</li>

=Conclusion=
If the elevations in MapInfo file look like the above, the DEM or TIN input has been successful! A similar process can be used to view the land use (materials) areas with the '''M01_5m_002_DEM_M.asc'''. 
If the TUFLOW\check\2d\ folder contains a DEM_Z.flt and not a DEM_Z.asc then the command "<tt>Grid Format == ASC</tt>" needs to be added to the .tcf file.
