Mapping Plane with Ground Coordinates
Scenario
You need to lay out a petroleum well site at coordinates specified in a
US State Plane map projection zone. You wish to use your RTK GPS
to do the stake out, but the site may require some total station
measurements to collect points not accessible with GPS. You want to
be able to work with your job file points in both the map projection
grid coordinates and in ground level coordinates.
Objectives
This tutorial job will teach you:
¾ How to start a job and import ASCII coordinates.
¾ How to start a survey and select a map projection zone.
¾ How to do a mapping plane localization.
¾ How to use GPS Stake Out.
¾ How to use the Ground Coordinates setup.
¾ How take conventional measurements on the ground with a
selected map projection zone.
¾ How to switch from Ground Coordinates back to grid coordinates.
¾ How to set the survey scale factor for a point on a map projection.
¾ How to use the survey scale factor when storing COGO points on a
map projection grid.
Procedure
1. Start a new job.
• Choose not to use a control file. Use point 1 and accept default
starting coordinate.
2. Import control coordinates from ASCII file
• Go to File > Import, and set the type to Text files .csv. Select
TdsControl_Oregon North metric.csv.
• Create a layer named CONTROL to import the points onto.
This will protect these points as job file control.
3. Start a mapping plane survey.
• Go to Stakeout > Stake Points to open the Start GPS Survey
wizard. Choose to Select a Mapping plane zone> to open the
Select Coordinate System screen. Choose US State Plane 83
