....depends on what car you are driving,...and if you have your "smart phone" paired with your vehicle (also, are you subscribed to any telematics automobile service?).... Automobile manufacturers who offer telematics will tell you that you are only tracked if the in-built system is engaged by...

That's the right idea; you are on the right track with this. Google uses a whole host of digital elevation model (DTM / DEM / TM) product to come up with their whole earth elevation numbers...example: for the USA, they extract elevation data from NED (10 meter), SRTM (30meter to 90 meter), and...

....OK, cool. Personally, (not legal advice) I would like to see actual case outcomes resulting from this Statute. But in the interim, I will take out just-in-time situational hobby drone insurance for each flight in Florida I make.

Read the above. We are discussing the potential collapse of the hobbyist photo drone realm because if ill-conceived and over-stepping laws (to put it mildly). There is absolutely no legal advice being proffered nor inferred in this discussion. erkme73 and I will continue to discuss this issue...

...the "surveillance" wording is so broad, it could be debated in court for days, costing the defendant $ dearly, yes?

Thanks for the clarification. Now, under the above broad-stroke, it could be argued that no one engaged in hobby drone flying (read: not flying under the (4) EXCEPTIONS clause) can fly a drone anywhere in Florida, because of the wide-angle nature of the drone camera (ie. as soon as you lift off...

...I read the Chapter 934 "SECURITY OF COMMUNICATIONS; SURVEILLANCE", section 934.50 "Searches and seizure using a drone." through, and it appears (to me; however, I am not a lawyer) that the entirety of 934.50 pertains exclusively to law enforcement agencies, including Homeland Security for...

....I wonder of full spatial awareness ToF 3D cameras are going to be in DJI's near future drones? These devices do real-time 3D environment full spatial awareness mapping (LiDAR on steroids)...apparently, most new smart-phones will have this built-in, shortly. So, drone optics can't be far...

Here's a Forum member post link, listing compatible cards for P4P: Actual micro sd cards tested by DJI to work with Phantom 4 Pro

....that UHS Speed Class 1 (U1) card has an advertised write speed of "90MB/s", but I don't see any independent speed tests on that particular card on-line. Also, is this card on the list of DJI "tested to work with" SDXC cards (you may want to verify with the DJI site, or someone who is...

....vis MicroSDXC cards: I wonder if card users really understand the difference between UHS Speed Class 3 (U3) and UHS Speed Class 1 (U1) card capability? And, the difference between a card writing bitrate at say, 63MB/s and 504mbps ? It would probably be relatively rare for the P4P camera...

....an interesting example: ....Florida is just about done (may be done now?) migrating to the NAVD 88 standard....all Fed agencies are required to upgrade NAVD 88. Inside the boundary of Florida water management, the elevation numbers from NGVD 29 to the new standardized datum shift the...

...this may be of some use: How does Pix4Dmapper define Omega, Phi, Kappa How does Pix4Dmapper define Omega, Phi, Kappa?

....Canadian spatial analyst here (retired). I also worked as a cartographer (paid under numerous research grants over the years), but I am NOT a surveyor (though, I have studied extensively the field of geodesy). I had done extensive "field surveying" for research purposes (mapping everything...

....interesting. Thank you. The whole world of *very low cost SfM* seems to be just emerging, with the inexpensive aerial / camera technology coming out (like the P4P, with its new 1 inch sensor) ! I've been doing some investigating into the current limitations of SfM (I always compare SfM with...
