The city of Frisco, Tex., published state plane coordinates were “ground scaled” into surface coordinates for the purpose of establishing a hybrid coordinate system to be easily used by surveyors. Nineteen city monuments were found and collected by GPS observation using real-time kinematic (RTK) connected to the Texas RTK Cooperative Network. The network creates a virtual reference station near the GPS roving receiver, allowing the surveyor to use the rover unit by itself without the need for setting up a base station on the project site. Using a GPS manufacturer’s standard protocol, localizing ground-scaled GPS vectors to the city’s hybrid values yielded acceptable horizontal (H) and vertical (V) residuals over a 233 km2 network. Two out of 19 monuments observed explained maximum residual error (H = 0.029 m, V = 0.082 m) with no significant differences in the mean ΔN and ΔE between published grid, hybrid, and surface coordinates (P = 0.77). This paper will illustrate and discuss the procedures and results of this project.
