Digital Terrain Modeling (DTM)

Our topographical surveys are surveyed in 3D. Therefore in addition to providing contoured plans, we are able to provide 3D digital terrain models (DTMs) on disk. This is a computer generated “wire-frame” model of the topography of the site. These can be rendered if required.

We create DTMs for most topographical surveys that we carry out; as this is used for the creation of the site contours. We can also produce site cross-sections by utilizing this information, if required.We often provide 3D “triangle” file DTMs to clients for them to use for site volume calculations, optimum design levels etc.Please also refer to our check surveys section and our topographical survey section for associated information.
