Stake DTM
Stakeout Stake DTM .
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.
The reference DTM surface can be defined by a layer in the current
job or a file loaded on the data collector. Either a DXF file containing
a triangulated irregular network (TIN) or a digital terrain model
(DTM) file can be used.
Consult the User’s manual for more information.
Note: The speed performance of the Stake DTM routine is enhanced
when using a DTM file as opposed to a DXF file.
DTM Source: is where you select your
reference DTM surface. If using a layer, toggle
the button to Layer and then select the layer
from the dropdown list. If using a DTM or DXF
file, toggle the button to File and then tap
the power button and Browse then select the
appropriate file.
