![]() After setting the camera, close DJI Go and open your preferred flight app.įor most purposes, I set flight altitude at 250 feet, front overlap at 80% and side overlap at 75%. I do not let the flight control apps control the camera settings. Better to capture a few hundred feet outside the area you need than to cut off 10 feet of what you do need.īefore the flight, in the DJI Go app, I set white balance to Sunny, and set my exposure and leave it in manual. Allow at least one leg of overlap between flight plan areas. ![]() Nothing worse than being 6 batteries into a flight and having the app crash or losing the connection and not being able to continue. I would love to know what others who map large areas have found works for them.įor large areas, I break up the area into individual 300 acre flight plans. Precision Hawk made a great app but it quit working a few firmware versions ago and I haven’t tried it lately. MapsMadeEasy and the DroneDeploy app are my next two, in order. I personally prefer to fly using the DJI GS Pro app for most missions. You can fly the mission with any flight control app and upload the images to a DroneDeploy project to process. My clients (oil & gas and heavy industry) usually use the ortho map outputs for documentation, and we use the 3D outputs to combine with engineering files to create project visualizations and interactive walk-thrus.įor the OP, you do not need to use DroneDeploys app to fly the mission. I have mapped areas as large as 1200 acres in a day. ![]() I have found DroneDeploy to be the most cost effective solution for creating large area maps and 3D models. But I still suggest that you test out all the available mapping apps that are out there and see if they fit your needs. You could try dragging waypoints in Litchi to the desired offset, but this gets quite tedious, and I know because I've struggled through it. If you want 75% overlap, your paths would be 96 feet apart. As for determining offsets, just calculate the your camera's image width at a given height, and multiply by your desired offset (100-%). Although it should produce similar results. Lindsaybev - I actually use Microstation for Litchi planning, not AutoCAD. Good processing computer, but nothing exceptional. Larger projects may take 4 or 5 hours of actual processing (not counting cleaning point clouds, orthomosaics, etc.). Pix4D on desktop is my mapping software with similar processing times as Meta4. This seems to be high enough resolution for my mapping. Larger projects i will bump it up to 400' altitude (US maximum) with 1.3 inch GSD. Many of my projects are flown at 250' altitude, yielding 0.8 inch GSD. I also use Maps Made Easy as I like the way they structure the payments - as in pay as you go, and I find that even with the lowest payment option I get my images back within a few hours. ![]() Depending on the surrounds, I find that an altitude of around 40-50 metres provides the best detail for my purposes. When returning to base I always toggle back to 'P' at about 15 metres above the ground so that I can control the decent. always have the controller toggle switched to 'F' and not 'P' for take off. Always launch the drone prior to the mission to ascertain the height of the highest structure/tree, and reset the mission height to clear all of these obstacles. Three key points that I have learnt are: 1. I use drone Drone deploy on my desktop to plan my flights prior to going into the field as you have the option to minimise shots, allow for a second battery install, and also have the ability to allow for crosswinds (albeit this bit has to be done in the field if required). I also use Autocad to digitise my images but would never use it to plan my flight mission as there are too many mistakes that can be made. ![]()
