Create a Terrain Model with Points

 

Points (survey data)

There are many ways to develop a representative surface that can be modeled. The surface must resemble, as much as possible, the actual land area that is to be developed. The original data may be; a written or ASCII list of survey points, a drawing of a set of contours (paper or digital), an electronic file in DEM or SDST format, or a combination of any of these. In almost every case, except the digital electronic files, you must convert the data to actual points in Rhino, add any additional modifiers and apply a routine based on a Delauney algorithm to generate your surface of triangular 3d faces. Generally the points provided by a professional surveyor need only be tinned using Points to Mesh without additional work.
