For what? Navigation & obstacle avoidance? No, there's no need.

Will for collection eventually, when it's more developed at that scale.

It's about 5 years after the open source options had terrain aware working, but better late than never Dronedeploy!

I'm heading out to this site right now, so we'll see how it goes on something with 500ft of relief.

Murphy's law, of course. I forgot to bring the iPad with me and it doesn't look like terrain following works on Android (from what I can tell), so I didn't get to test it out on this project.

I think this is my 5th or 6th flight on this project and the homebuilders really like this stuff. I made a raster/basemap version of the DSM for one of our surveyors the first time I flew it and pulled it into CAD as a layer because he didn't want me to spend 2 days building a surface just so he could trace the lots (needed to see them in 3D back then). He accidentally included that layer in his eTransmit to the client and they used the hell out of it. Now they keep sending me out for RASTER of the surface and some misc aerials. I'm always underestimating the value of the simple stuff.

Sweet! P3? Former coworker/surveyor just picked one up off facebook.

I don't remember if it works with that one, but check out the litchi app

Yeah P3, just flew it for a test drive and it's pretty nuts. Was not ready for it's power

This was a fun one. The process of unlocking DJI drones when in class D airspace is still kind of annoying, but it works a lot better now than it used to. I also met the new ATC manager that started a few months ago and the guy is a badass. A couple decades older than me, but he's into a lot of the same stuff and he's lived in 3 of the places that I have too.

Took the Mavic Mini with me on lunch to get some pictures of the river flooding. It's actually really convenient to grab & run, but I'm not a fan of the sensor and the wind tolerance on the drone is pretty low. Probably around 8-10mph.

Dang. Glad my area does not flood much. Hurricane occasionally, but no flooding really.

Oh oh what you think of the new dji spin off lidar company? Their version of lidar looks interesting a "spiralgraph" style pattern shoot. 250k shots per second etc.

Bandwagon:


~3cm horizontal and vertical accuracy without GCP's

kits they use to install on your drone, they do it at their office, send drone to them, they send updated drone back

kit to do yourself-3200 for the top level 1/2 kit(186 channels), 2600 for the l1(72 channels):

of course we need gcp's. cannot do survey layout work without it(well you CAN with gps but personally, i'd rather have a traverse done by my total station to the gcp's since THAT is accurate to 3ppm.) BUT, if you can get 3 cm without gcp's i imagine with gcp's, 3cm accuracy(1.25 inches basically) will turn into about 5mm accuracy.

price is good though i think. you have to remember for MY area, all my work for survey topo etc, we do not use GPS at all for our normal work it is only doing a drone flyover for topo that even ROUGH gps(the drone data) is used.

lidar in my opinion will be the next big survey drone combination, they have them now, but they are about 3x the price of the p4pro and this.

The phantoms are too easy to break and have no redundancy. RTK adds extra setup and problems during flight, PPK adds extra time on the back end. Extra time that, in my opinion, we really don't benefit from because I'm still going to set almost as many GCPs with the RTK/PPK phantom as I do without. We aren't always on standard state plane coordinates either, usually we're on some sort of minor adjustment for a county or something. 1.5cm-3cm horizontal is about all we're going to expect most of the time anyways because of the image resolution and the fact that any of your drafting is done off the resulting imagery. If you get better than your GSD, it's just because you're a lucky guesser when trying to determine if that curb line falls in THIS pixel or THAT one. Vertical is a different story in some regards I guess, but we're pretty tight on that already.

I dunno man, I could definitely be wrong, but those things still look like more money and effort/time to use on each project without providing any real benefit over what we're doing now. It sounds even less appealing to me in a city because your GPS is going to be shit flying in there, yea?

ya pretty much, which is MOST of the time we don't fly in the city. site's are just too fucking small.

one job we did this week, the lot was 6000 square feet(40' by 150' lot)...6 story building that is 40' wide by 50 deep, with a ' 38ish wide by 80' deep parking lot..Real hard to figure out where the lot lines are......... job we did the week before, the lot was 30'x40' with an 4 story building that filled the entire lot.... (they are adding a floor) etc etc etc.

larger city job,,, 200' x125' lot=25000 square feet, could use the drone, but, the 6 story building covered about 20 thousand of the lot, and it was flat parking lot for the rest, the building was 125'x200' at it's longest extents (shaped like an L) heck we didn't even survey most of it, because we had done a job a year before right next door so we had the survey already done except for the parking lot.

That job next door was fun. some IDIOT!!! did not pay attention to the overall control street to street and the fact that,,,MAYBE.... something was wrong with his survey, lot in question, no building,,, 130' x125 feet deep (street to street-silver to west second st)...going from the EAST side traversing west(what the IDIOT DID)... the building on the right(east side) was a foot over the property line, the large building (mentioned previously) on the west side was 1 foot inside it's lot,,,but the physically measured distance between the buildings- our lot- was 129.99 feet.
finding control from the WEST side- street layouts, city survey notes(boston used to have a survey department and all their records are online) plans of record, and bounds found -plan from 1901 shows the WEST building ON the property lines with zero setback and holding the WEST side control, shows our lot perfectly placed between the two buildings........ where common sense says it should have been in the first place.

Now that we have some of the engineers using my point clouds, and our Vancouver crew just picked up a scanner, I'm working on improving my point clouds in urban areas like what you're talking about. I copied a concept that I saw from a manned aircraft company in Georgia and how they fly entire cities to produce quality point clouds with photogrammetry alone. I only started playing with it this week and I've used it on two flights, but the first results look really good so far. I'm basically simulating a 6-camera 3D rig as much as I can with SfM.
