How large an area can an Inspire/P3 map?

Not in the DroneDeploy simulator. That is for aircrafts with the DroneDeploy CoPilot.

Have you solved the issues of being able to control the DJI drone from that far away and also the battery life issue? I would imagine those are the two largest issues.

At full tilt and low altitude, we can get a P3 out about 6 miles and back on 60-70% battery. That leaves 40% for on-station mapping. BLOS piloting is done with a 5.8GHz FPV system and a DBS long range mod.
This setup gets us into remote drill sites manually, but we’d like to use DD to plan the flight end-to-end. It would be nice if we could also use the simulator to test the plan before sending real equipment into the god-forsaken wilderness.

There is a DJI Simulator here:

and the windows driver here:
http://download.dji-innovations.com/downloads/dev/OnboardSDK/DJI_WIN_Driver_Installer.zip

Which is normally used for developing against the SDK.

You have to plug a usb from the windows machine to the aircraft’s usb port then start the simulation. Make sure props are off. You should then be able to set the lat lng on the sim and then run dronedeploy with the aircraft in the simulator.

The newest version of the app is the only one I’d try this with. It still sounds like a scary flight either way being so far away. The new version will be in the play store later today.

hey manu !!

Great work.
i just wanted to know the altitude of that inspire in your mission.

Please reply asap.

I think manus flight was right under 400 feet.

Hi @RickWorsnop,

I’m Vikshut, from Bangalore, India. I was wondering if you did the entire flight using the continue mission feature on DD and if it worked out well for you. It would be great if you can send across the flight details.

I need your advice on something -

I’m going to be mapping an 850 acre coffee plantation site next week. It’s got a terrain variation of 250 meters (820 feet) and I’ve got access to the highest point in the site from where I’m going to be flying the drone.

I’ve planned the flight off line and found the max distance that the drone will fly from the remote to be about 2.5 km (1.6 miles). I’ll be flying it at an altitude of 82 meters (269 feet) AGL and BLOS is not really an issue here. I’m right at the edge of a forest here.

Should I go ahead with this plan or would you have me do it differently, based on your experience?

Looking forward to hearing from you soon.

@chasemgray, would be great if you can add to this as well.

Forgot to mention the aircraft I have - it’s a DJI Phantom 3 pro.

Sounds as a massive task to do. Hows the wind in the area? Estimate you gonna need 15-25 batteries. And the image gsd will vary a lot because of diffrent heights.

The wind speeds should be about an average of 4.5 m/s at that height (82 m AGL) I’m going to be flying it at. Dronedeploy tells me the total flight time is about 138 minutes for the flight I’ve planned from the dashboard. So, assuming 15 minutes of flight per battery, that’s about 10 batteries. I have 3 batteries, so I’m looking to fly 3 batteries at a time with 2 to 3 charging breaks in between.

Yes, I’m concerned about the gsd variation as well, but I’m not quite sure how to take care of that. Any suggestions? The estate owner’s main requirements are to mark his boundaries on a map and measure total area, measure the productive growing area of his plantation, and measure areas of various features like water tanks and roads in his estate. Would the gsd variations (altitudes would range 82 - 332 meters) come in the way of doing these measurements accurately?

Regarding varying altitude due to the terrain, I have a question.

Could you fly out manually and go down to a lower altitude, then reset home position, start DD based on altitude above that new HOME altitude?

I know there would be risks associated (return to home, etc), but could this work?

How far can we send inspire from point of takeoff for mapping…??

You can definitely send it as far as you can maintain a signal. You can also send it further but you will lose signal. The drone will continue mapping, but you won’t be able to see the live video feed or know the battery until it either returns due to low battery or is finished.

I am looking for ways to map a surface area of 75 square km. The main problems are to find a way around the altitude difference between different take off points and planning efficiently the area so it can be mapped.

Has anyone ever tried to map significantly larger areas that require anywhere from 10 - 50 flights to complete the mission?

A couple users have done massive maps, up to 8000 acres, but no one has done as many as 75 square km (17000 acres). Doable, but a lot of flying!

Challenge accepted then :smiley: The main problem I am facing is mission planning. Not sure how to design the flight path. The drone deploy mission planning really is very limited when it comes down to planning a massive project. It would be good to be able to design an area and then have the software divide it into different portions so that you can map it piece by piece.

I have recently ordered a Mavic and am patiently waiting for the long backorders to be filled.

It’s very exciting to see what might be achieved with DD but I am concerned about the mapping area limitation. Most paddocks (fields) that we have are 350 to 400 acres but for the most part I don’t really need a lot of detail or statistics, just to produce one stitched together photo of each paddock.

Does that sound possible with DD or am I better off just free flying, taking a few photos and manually stitching them together?

I’d also like to know altitude…

So my million dollar question do I buy 3 or 4 inspire 2.0 with extra batteries or go for the new Ebee SQ ag drone for 12-15k with the multi spec with up to 500 acres at a throw. I like the one hit wonder, but i like redundancy and flexibility of a VTOL offers, mainly we are wheat,corn,soybeans here with possible of some surveying and site scanning. Please, your thoughts …

I am facing a problem with my new map. I was making a big map and separated mission in 4 pieces. All photos was taken correctly, but when im processing my map im loosing some areas. Here is the example http://drdp.ly/cEPwuU
This map should look like a square and what i get it this. Any suggestions?

I routinely cover 160 acres on one battery pack with a P4. 400 feet altitude with 60-75% overlap. If you can launch from somewhere near the middle of the real estate, you should easily cover 400 acres with 3 flights.
