To stake out a DTM

For information on supported DTMs, see DTMs and surfaces.

1. Tap Stakeout / DTMs.

2. Select the file to be used.

   All DTM files in the current project folder are listed.

3. If required, in the Offset to DTM field, specify an offset to the DTM. Tap and select whether the offset is to be applied vertical or perpendicular to the DTM. The V.Dist DTM value is to the offset position.
4. To change the target or antenna height, tap the target or antenna icon in the status bar.

   If the target or antenna height have not been defined, the elevation and cut/fill will be null (?).

5. Tap Start.

   The coordinates of the current position and the distance above (cut) or below (fill) the DTM.

   Unless you are using a conventional instrument that supports tracking, the values appear only after you have taken a distance measurement.

6. When the point is within tolerance, measure the point.

When staking out the DTM, if you are outside the extent of the DTM or in a "hole", the DTM elevation and cut/fill will be null (?).
