Sorry if you took my answer as rude, if so I apologize. If you were just interested in what type of work I do I will tell you.
I am the Principal Geophysicist for an engineering consulting firm and previously I worked for the US Army as a research geophysicist for almost 20 years. I have a PhD in geophysics and have taught classes in GIS and remote sensing. I have been doing photogrammetry for around 10 years. I started with fixed wing platforms like then Event384, then started using multirotor platforms like the Turbo Ace Matrix Pro E, the DJI Phantom 4 Pro, Mavic Pro 2, Matrice 210 v2, Riegl RiCopter, and others. I have done GNSS surveying, LiDAR surveying, and photogrammetry all over the world. I have used LiDAR systems from Trimble, Riegl, Leica, and Faro. I have used pretty much every GNSS receiver Trimble has made in the last 20 years in autonomous modes, satellite correction versions from OmniStar, post-process my data against base stations that are CORS or ones that I set, RTK, PPK, and static sureys to establish benchmarks. I have tested or rented most other brands of GNSS receivers as well.
All of the positioning stuff is just a way to improve the accuracy of the locations of my geophysical measurements.
I started doing photogrammetry as a way to generate high resolution orthophotos on which to overlay my gridded geophysical data.
I purchased the first version EMLID receiver when it was on Kickstarter. I then purchased multiple REACH RS units for testing and low cost postioning. I have held off on purchasing the RS2 or the M2 as I was trying to figure out where they would fit in my workflow.
I started collecting a lot of photogrammetry data from boom mounted systems when I was working on either airports or US Air Force facilities. My general approach is to mount a camera on a carbon fiber boom above and in front of my vehicle. I have usually used a really cheap GPS receiver next to the DSLR or mirrorless camera that I have on the boom. I use HoudahGeo to synchronize the camera time and GPS time so that I can then interpolate the camera positions from a log file. This position data isn’t very accurate so I was considering using a EMLID M2 or RS2 if they could both use the hot shoe adapter.
My question is if the RS2 can utilize the hot shoe adapter.
