No, not yet. Nearly every other app supports the P4Pro.

Try Altizure and Map Pilot (iOS only)

Altizure and Data Mapper are available for Android, and work with P4 Pro.

Since you use the p4p do you think that this is the best drone for the buck to use for mapping today?
What app you use for mission planning? Is the map pilot the one you posted?
Also anyone has opinion for the software http://www.3dsurvey.si ? It looks very easy to use from the tutorials i checked.
Any feedback is welcome.

Yes, that was Map Pilot. Not a single best app out their yet. I use Map Pilot most of the time, as it can use a polyline, and can calc for multiple batteries. has a lot extra stats and features. But it does allow me to tilt the camera, only takes nadir images. Pix4dCapture can change the camera angle, which helps get under building overhangs.

I have never seen 3dsurveys.si before your link. There are a lot of online websites like Drone Deploy ($299 per month) and Skycatch ($749 per month) that will process the data. The FREE versions do not allow for GCP entry, only the Premium plans allow that.

I believe the DJI Phamton 4 Pro with 18MB camera, 1" sensor and mechanical shutter is most economical and easiest to fly sUAV for aerial imagery. Don't be fooled by the price air the aircraft $1500. You will spend twice that amount for accessories like a hard shell case $300, extra batteries $170 each (need 3 at least), 64Gb fast microSD cards, Prop guards. DJI custom care (insurance) and Gimbal guard. You will need a tablet or cell phone. I recommend the 9.7" Ipad Pro w ith 128Gb (need room to store maps) cost $650.

Also need a fast PC, with latest technology cost about $5000 to $10,000

Pix4DMapper Pro cost $8700 or $350 per month.

You also need photo targets and a way to measure those GCP's. Usually done with RTK, so that's another $15,000 to $30,000.

It's nice to see this thread is still going and it's good to hear more about the P4P. I want one already even though my P3P serves my purpose just fine.

It's amazing how quickly the new technology drops prices on the old "new" technology. I see on amazon that the Phantom 4, which was about $1400 a few months ago, is now $900. That P4P will be within my reach next year when the new best thing comes out!

Cheers and Happy Holidays.

DJI is introducing a new drone about every 6 months. Every time the camera is better, battery last longer, more features added such as lidar sensors for obstacle avoidance, yet the price stays the same. Sure glad they are doing this. Would hate to have been an early adapter spending ten's of thousands on a drone that is out of date in 6 months. The camera and sensors appears adequate now, I hope see big improvements on battery in the future.

I am surveyor so i have the equipment needed for the GCP's. I don't have the latest i7 but i dont mind spending more time on processing the data.
The uas and software is what i need for now and i think that P4P is a good choise for small jobs. Right?

Apparently they have already upgraded the camera, as the one I just got has a 20 mp camera. I intended to use this iPad with it, but I had to upgrade the iOS to run the Dji go app. Then it told me it wasn't compatible. It's a 4th generation. Hate to buy another full size, so looking at a iPad mini.

Yes, the P4P will work fine for projects up to 100 acres.

I met a guy at Pix4D training who mapped 1000 acres with a pair of P3 DJI's. He said the post processing took 120 hours on his PC.

Be prepared to not use that PC during processing. It will use 100% of every core you have in CPU, then mouse will barley move.

Yes i know, i have demo of pix4d, photoscan and context capture with sample sets and the processing is very demanding.
I saw also the 3dsurvey and it looks very easy workflow and i like that it can automatically recognise the gcp's if you locate 2 at least in the photos(i think they must have a geometry algorithm to detect the rest gcp's).

I tested Context Capture. One nice feature is that you can process it across multiple PC's on a network. Like the old render far days. But is seemed to lack the features of Pix4D. One nice part of Pix4D is they too are actively introduce new technology to the software. They seem to have a updated software version every 60 days. With Pix4D pro Mapper you can now upload the data to their cloud, and use Pix4D computers to post process the data. You will need a big internet pipe line to upload a few Gb's of data. I have TimeWarner Cable intert with just 6Mps upload and 60Mps download. By the time you upload the data, you could have processed it yourself.

Hmmm. If you upload the data and they process it, would you still need a beast of a computer? Does the rest of working with the already processed data take as much juice to work with?

I have everything except a drone and the software. But my computer is definitely way below standard. I don't mind buying a better computer to work with already processed data, but I'd rather not buy a 10k supercomputer to process it with.

No, you would not need much of a PC if you used cloud processing. You may want a very fast internet connection. You will be uploading hundreds of photos, then downloading large files of geo TIF's and Las point clouds.

The P4P high resolution photos are 8Mb each. Ortho mosaic photos can be 200-500 MB, while the point cloud may be over a GB.

I just ordered a new CPU to upgrade my PC from a 4 core to a 10 core i7 overclocked at 4.2Ghz.. I already have 4 SSD drives in a RAID 0, 64Gb RAM, and GTX 1080 graphics card with 8Gb RAM.

The upgrade was $1700.[SARCASM][/SARCASM]

Hi,
Can anyone send me original photos from DJI Phantom 4 Pro, just 1-2 images? I want to buy this drone for 3D model creation of the open pit mines and volume estimation, but I can‰Ûªt find 90 degrees sample photos from DJI P4P.

Lee,
Do the prop guards you use interfere with obstacle avoidance?

No, my prop guards do not interfere with OA, but the Gimbal guard does.

For small jobs i dont think you need the latest i7 pc. You just have to have a spare pc and let it do the proccesing. It will just take longer to finish.
P.S. Leegreen since you have p4p can you send us via dropbox or some other way some vertical photos?

GTO234,

I agree. One good thing with Pix4D Pro. When you purchase a full version, it includes two licenses. So you can run step one on a laptop to get things started, then run step two and three on your office PC.

I have a small test flight I did recently, and will upload a few JPG's, the Ortho Photo and a Pix4D screen shot of 3d to my company file share. You will need to create an account to download it. Only took 40 photos at 280ft AGL, a short flight due to temperatures below freezing. One of the few moments there has been sun shine here lately.

Click here to download 164MB files If you wish to see the files, please send me an email (lee@leegreen.com) for access.

There is a small software bug with the P4P time stamp. When using a 64Gb micro SD card the date stamp is off by 15 hours. Have since learned that this is caused when the card is formatted exFAT, by default. The card must be reformatted at FAT32, but Windows will not format it at FAT32. You must get a 3rd part app such as guiformat.exe

I don't have any worthy projects right now. It is the winter here, and I'm located east of a Lake Ontario where we get a lot of Lake effect snow. It has been cloudy most days the past few months. We have had over 80" of snow so far this season, with 24" to 36" of snow on the ground now. When the sun does come out the angle is so low we get long shadows.

Winter conditions
