Store Offset Points - Screen 3
The third Store Offset Points screen is used to define which offset points will be stored.
From Station: is the station where the stored offset points will begin.
To Station: is the station where the stored offset points will end.
Station Interval: is the distance between the stations where offset points are stored.
Note: If the Stake Corners option is selected in the Stakeout Settings screen, offset points will also be stored where
ever the horizontal or vertical section of the road changes.
Start Point: is the point number that will be assigned to the first offset point that is stored. Each stored point that
follows will be assigned the next available point number.
Description: is the description that will be assigned to all the offset points that are stored.
Center Line: offset points will be stored at locations on the centerline when checked.
Edge of Pavement: offset points will be stored at the end of the first segment (the edge of the roadbed) on the left
and/or right side when checked.
Curb: offset point will be stored at the end of the second segment (the end of the curb or ditch) on the left and/or right
side when checked.
[Unselect All]: quickly unchecks all the checkboxes.
[< Back]: returns to the previous screen.
[Store]: stores all the offset points based on the information provided.
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.
