GPS Control Point Reference Photo

If external control is collected for the project, the table below describes the appropriate documentation for this process. Download a printable form in PDF format here or in a spreadsheet (.xlsx) format here.

For each control point:

Entry Description
Point ID ID or name given to the point.
Source and datum (total station, GPS, etc. and WGS84, UTM, LRF) Identify the source for control point collection and the datum used during data collection.
xyz coordinates List the three-dimensional coordinates for each control point.
xyz covariance matrix or estimated error Provide full correlation if available (from survey adjustment or GPS baseline solution), otherwise provide estimated standard deviation or variance of each coordinate.
Textual description of location Provided a textual description for the location of each control point.
Image name with control point location indicated Name of image with the control point location clearly indicated.
Geometric constraints on reference features or control List any known geometric constraints for reference features or control.
Coordinate System Name of coordinate system, datum and projection.
