Automated Contouring Systems
Automated Contouring Systems
- DTM (DEM): Digital Elevation (Terrain) Models
- Array of points with measured X, Y, and Z
- grid method: borrow pit, computer interpolation
- irregular method: indirect method, with additional information to produce Triangulated Irregular Network.
- Assuming the triangle sides are of constant slopes, interpolate along the sides.
- breaklines: linear topographic features which have uniform slopes. Must be triangle sides. Note how roads are shown in the TIN and inthe contours.
