Advanced feature: Viewing and deleting a measurement in resection
To check the measurements to each known point, press
the
View
softkey on the calculated STN (sigma or
coordinate) screen.
To delete a measurement (because of large sigma values, for example), highlight the
measurement data or display the detail screen for the measurement. Then press the
DEL
softkey. The STN coordinates are automatically recalculated.
To continue resection observations, press the
Add
softkey. The input screen for the next PT appears.
The minimum data required for a resection is either three angle shots, or one angle shot and one distance shot.
If you use a distance shot, the distance between the target points must be greater than the measured distance.
Stn-Z is calculated from distance-measured data. If no distances are measured, then Stn-Z is calculated using
angle-only measurements to points with 3D coordinates.
dHA Distributed HA errors in each direction
dVD VD errors between measured distance and calculated
distance
dHD HD errors between measured distance and
calculated distance
