Description

Soft Material

Specify which surface must be used for the soft material type by clicking on the arrow and selecting a surface from the list. Thereafter, specify the search distance for relevant DTM data. Usually a search distance of 100m will be sufficient.

Intermediate

Specify which surface must be used for the intermediate material type by clicking on the arrow and selecting a surface from the list. Thereafter, specify the search distance for relevant DTM data. Usually a search distance of 100m will be sufficient.

Hard Material

Specify which surface must be used for the hard material type by clicking on the arrow and selecting a surface from the list. Thereafter, specify the search distance for relevant DTM data. Usually a search distance of 100m will be sufficient.
