This tool simply enables external DTMs to be imported into waterRIDE™.

 

TIN DTM's

The following formats are supported:

•12d ASCII format (.12da) the exported file should just include the TIN and no other layers),

•ASCII triangles (comma or space separated data as x,y,z,t per line, where t represents the triangle number),

•version 7 MicroStation file of 3D triangles, and

•the 3D faces within an AutoCAD DXF file.

All outouts will be TIN based DEM's (*.wrb)

Alternatively, DTM's can be created from RAW terrain data or a combination of existing DTM's using the waterRIDE™ Batch application provided with waterRIDE™ Flood Manager. waterRIDE™  TERRAIN is a separate tool for building DEM's from extremely large point datasets.

•ASCII Grids (*.asc)

•Gridded ASCII (*.xyz)

•Idrisi/Binary Grids (*.img/*.rst)

•ERDAS Grids (*.img/*.ers/*.ige)
