Digital Terrain Model (DTM)
The DTM module for xpstorm (which is an add-on for the base package) allows the graphical interface to create and contain an embedded digital terrain model (DTM) or surface model. The embedded triangular irregular network (TIN) can be created from manhole elevations, a file containing a series of X Y Z and (optional) string data or directly read from popular terrain modeling packages.
With the surface model incorporated into the project the user can create perspective views, drape geo-referenced images, obtain ground elevations automatically for nodes, cut cross sections for natural channels and view flooded results in 3D.
DTM Module for xpstorm allows the following:
- import xp12d TIN and triangulate X Y Z input
- shade the TIN to graphically show elevation
- adjust the TIN transparency and show contours
- adds elevation to the status bar, tracks the easting, northing and elevation of the mouse location
- Displays a cross section profile by drawing a polyline
- automatic calculation of natural channel cross sections for links
- automatic calculation of node ground elevations and inverts
- automatic generation of 2D grid elevation (requires the xp2D Module)
- adds terrain to the 3D perspective view tool
