Here is a map of the asbuilt survey we did yesterday for a subdivision we recently completed. The mission was done with 8 GCPs and 20 checkpoints using the Emlid Reach RS2 on the RTKNET CORS service. All analysis of the checkpoints, field stakeout verification and proposed surface model was within the 0.10ft construction tolerance! A testament to GPS machine control including our new GPS curb machine and a precise VDC Team.
