Ok folks! I went out on a limb today so I hope it doesn’t break before I get my good results back. Actually I have a Plan B, but it will crunch my deadline if I have to use it.
Went to a site on short request today to topo an area for a huge add-on to an existing project we are already working on. We are the utility and concrete subcontractor to a larger GC and they basically want us to take over for the existing excavation subcontractor that isn’t getting it done. Another story for another time, but they are built to mass grade and we have covered them several times when real accuracy is required. The amount of material required is estimated (by the GC’s engineer) to be around 120,000cy so they asked me to fly the drone to verify.
Got to the site, checked in with our guys and they already had a base station up so all I had to do is get my Topcon rover out and shoot in a control point to set my Emlid Reach RS+ base on. Tip: always shoot two points in vicinity! Setup the ERS+ base, turned on logging and got the drone ready. Turned on the Emlid P4P, leaving the M+ off and setup the flight plan. Flight plan ready, turned on the M+ and turned on logging. Flew, turned off the M+, drone and then base. I was in and out in 45 minutes. This normally would have required at least 5 GCPs and taken at least another hour to accomplish. Double that if I had been using the RS+ gear to set the GCPs.
Fingers crossed, but I am going to start Plan B now just in case…
