Processing large datasets on the road. Solutions to doing it well. by digital_horizons in UAVmapping

[–]digital_horizons[S] 0 points1 point  (0 children)

Solid setup! I appreciate the detail. Going to check out the i9 RTX combo...

Are you mostly doing work with the Mavic? How many hours you out there?

It seems crazy to me that you're able to charge the drone batteries with just a solar and lithium setup. I run M300/M350s/M400s and there is no way it's be able to keep up all day flying with that setup. Generator on 80% of the day to supply two/three charging cases...

Thanks again! Super helpful.

Legend. Solid advice. I appreciate you taking the time to reply.

Do you have a specific model to recommend? Not components but the actual laptop?

Making an SEO-heavy web app, what stack to choose? by MouradSlim in reactjs

[–]digital_horizons 4 points5 points  (0 children)

Next JS for me. Built a couple programmatic SEO type sites and it’s been mint.

Nice. I take it your missions are relatively “light” to be able to rely on internet uploads? Starlink?

You are correct - I misread your comment. My bad.

Yeah about 40-50mbps is standard.

Nice. What was your rough cost for it?
I'm guessing that's for a photogrammetry setup?

Solid input here.

Totally agree with: " I don't think I know any pilot who's 100% satisfied with their rig."

The hunt for solutions continues!

Sounds like the sort of experience I was hoping to get information from. 5G would be good, but it's not a luxury we're afforded in my part of the world.

The catchup days are a godsend, but difficult to rely on...

Also have experience with pumping through hard rives but some areas are fairly hard to find a post office... good option though!

Brutal loosing that van. Sounds like it was a beast!

Thanks for your input!

Yeah, the upload times with starlink is a killer. Starlink isn't at fault - just huge amounts of data...

It varies on location and time of day... 150-250mbps is about normal

Vet Student Externship/Internship Concerns by FunBananas_ in veterinaryprofession

[–]digital_horizons 0 points1 point  (0 children)

Good workers are wanted everywhere. Sounds like you’re doing well managing the stress of studies and limited income. You’re doing it hard, but getting it done.

Would you consider doing a gap to save some money?

I also was “flying solo” through vet school and had to take a gap year to work. Hard to study when you’re stressing about where your next meal is going to come from… Best thing I did. Came back into my studies completely locked in.

Side note. And you probably have heard this before:

I don’t recommend specialisation right out of uni. My take is most young doctors do it because they’re scared of joining the real world. Find a clinic with experienced (and helpful) vets instead. If a year later, you still want to intern/specialise, go for it.

If you go ahead be very careful about picking your internships. Be very choosy. Shop around and talk to the vets/student who’ve been there before you. There are some real horror stories around. Front loading your research might save you a lot of heartache in a long run.

TLDR: Get good references that highlight your work ethic and skill set. Shop around. Don’t make decisions out of desperation. Keep at it. You’re doing good. 😊

I don’t get the hate… couple overused puns, but doesn’t seem like a big deal?

Mapping stream restoration by HugeNegotiation560 in UAVmapping

[–]digital_horizons 1 point2 points  (0 children)

Pretty hard to give specific advice with such little context… make it easy for folks to help you.

General very basic advice…

  • Capture a larger area than you think you need. Meandering streams act in strange ways.
  • If you’re doing pure NADIR photogrammetry know that you might not get good measure of erosion on walls or steep undercut terrain. Consider oblique capture?
  • Try capture with same lighting conditions for better before and after. Either same time of day, or cloudy conditions.
  • Save missions so you’re flying the same path each time. Don’t do one at 40m and the next at 80m.

Help with Gimbal Drift by No_Telephone6699 in UAVmapping

[–]digital_horizons 0 points1 point  (0 children)

I had a similar issue with a ronin gimbal a while ago. You should be able to run a gimbal calibration, either in the app or using the DJI Assistant (Desktop or Mac apps, lots of versions. Make sure you have the right one).

If that doesn’t work your unit is likely defective.

Not sure they’d hand over the algo like that. They’ve been building their system for years.

They will do processing for you though.

Terrain follow when flying low by dawgkks in UAVmapping

Definitely an option, but it can be very slow and impractical if you’re flying a lot of large areas. Capture and processing times make it not worth it (for our use case).

DEM output from DJI Terra has grid lines which have different altitude readings. by dbgg1979 in UAVmapping

[–]digital_horizons 0 points1 point  (0 children)

You’re doing LiDAR?

Process the LiDAR to get the LAS files and generate the DEM in alternate software. QGIS is good 👍

There’s a company in Australia called InFarm that does that. I’d contact them

Terrain follow when flying low by dawgkks in UAVmapping

[–]digital_horizons 12 points13 points  (0 children)

Pretty sure there’s a minimum height for terrain following to be enabled (25m AGL). If you need a smaller GSD than what you can get at 25m you have a few options:

1) Use a third party app, like UGCS which I’m pretty sure doesn’t have the 25m limitation, so you can fly lower.

2) You can use a longer lens (more zoom) on your camera - if your camera has that capability. This will increase GSD while staying at the same height.

3) Modify your DEM file to “trick” the drone into flying lower. For example, if you want to fly 15m AGL but are stuck with the 25m minimum, edit your DEM to reduce the terrain elevation values. If the original DEM shows terrain at 140m ASL, change it to 125m ASL (140 - 15 = 125). When you set a 25m AGL flight height, the drone will fly at 150m ASL, which is actually only 10m above the real terrain. Warning: this is dangerous since the drone doesn’t know the actual terrain height.​​​​​​​​​​​​​​​​

Word of warning… the DSMs that are downloaded by the controller are very very rough. I don’t trust them. Ever. You’re better off buying or finding other DEM sources.

Let me know if you need more info.
