Check Control Network
This tool will analyze the control points/benchmarks in a topo project to find duplicate points, names, and invalid codes and select points to be included in the control file. Download a Site Properties zip for your site from Champmonitoring.org.
If using a Site GDB, run the Control Network Check Tool. (If using a topo project, proceed to the Export Control File Tool).
Open the control points attribute table and check the following:
|Valid||Unique point with a valid code.||None - The point should be included in the control file.|
|Invalid Code||Description code is invalid (2012 standards).||Enter a “0” in the Control File Field.|
|Duplicate Point||Point has the same description code and spatial location as a previous point.||Enter a “0” in the Control File Field.|
|Duplicate Name||Point has the same description code as another point, but they are in different spatial locations.||This may indicate that surveys are using two different transformations.
Control File Field:
This field indicates which points will be exported in the control file.
- Points that contain a “1” are included in the control file.
- Points that contain a “0” are not included in the control file.
You can adjust the values in this field to include or remove points in the control file as needed.
