DTM Stakeout

The Stake DTM routine allows you to stake an area and get cut/fill

information between the point being staked and a reference DTM

surface at the same horizontal coordinates. You can also obtain

volume information between the surface being staked and a specified

reference elevation or the reference DTM surface.

Reference DTM Surface

DTM Stakeout requires a DTM surface that defines the reference

elevations for the area that you plan to stake. There are three ways to

define the reference surface:

• A DXF file that contains a triangulated irregular network

(TIN).

• A digital terrain model (DTM) file.

• A separate layer in the current job containing several points

on the reference surface.

Survey Pro will use any of these three methods to compute the

elevation information at any location within the boundaries of the

reference DTM surface.

TDS ForeSight can be used to create a DXF file containing the correct

information from a JOB file. ForeSight provides several options

when exporting a DXF file and all the options will include the

required 3D Face, or TIN information.

Both TDS ForeSight and Survey Link will export a DTM file from a

DXF file.

Note: The speed performance of the Stake DTM routine is enhanced

when using a DTM file as opposed to a DXF file.
