28. What is a DataSheet?
A data sheet is the principal information product for NGS. It combines control-point position and height information in a single format. Data sheets are retrieved directly from the NGS database by specifying a PID (Permanent Identifier), control point name, area, or survey project identifier. For the CORS sites NGS provides a data sheet for both the L1 phase center and the antenna reference point (ARP). Examples of data sheets for these points are included.
