寻找一种从设备捕获高程和位置数据以创建地形图或模型的方法

Question

I'm in the process of buying a 7.5 acre plot of land in a wooded, hilly area. I would estimate that the elevation varies about 50 feet from the bottom of the creek to the top of the hill. I would like to find a good method for measuring the topography of the land so I can create a 3D model. It would be tremendously useful to be able to try out different land development ideas and to simulate locations for future buildings.

My low-tech version of doing this would be to set up a laser level and go around taking elevation measurements in a 3' or so grid pattern. As I thought about that, I realized that smartphones and similar devices have quite a few sensors built in that might make this a lot easier.

I learned about software that will use a drone to capture data and images to automatically generate a topo map and 3D model. Drone Deploy is one such tool. I do have a DJI Phantom 4, but I don't know if it's feasible to fly such an intricate path among trees to scan the entire property. I wonder if there's another way to use this amazing modern hardware (phone or drone) to make my task easy.

I would appreciate hearing any thoughts and ideas about this!

Answer 1

The thing with dronedeploy is that you fly above the trees usually 30meters is ok. In a cross pattern.

Why do you want to fly between the trees? You have to explain that first.
