Mapping Mountain with Inspire Pro

Hey Everyone,

I love the app, it has worked for me well in the past but I have a new challenge. I have to survey a hillside that is at a 35-45deg slope and some GCP's will be set up before hand. My thought is that we shoot with the camera faced directly down on normal projects that are relatively flat to avoid shooting the terrain at any oblique angles. So when shooting a slope or hillside in this case that is so drastic, we would be shooting an oblique angle...Should the angle between the lens and terrain be close to perpendicular? Should the drone attempt to follow the slope of the terrain to keep a constant elevation. To my knowledge there is no such functionality yet...In my case I believe the height of the slope has a peak of something like 600ft above T/O. Most of the area is inaccessible by foot, hence the need for aerial survey. Any ideas or setup tips?

Using an Inspire 1 Pro with 12mm lens.. Is there a post on optimal settings for the X5?

Respectfully,

Jaron

There is nothing different really that you need to do for the X5 and 12mm lens other than make sure you have the setting set properly for the camera and lens option to make sure the overlap is calculated properly.

Perpendicular to the ground imaging will work but the map will still get resampled from above so it won't really help. Mapping something steep like this will introduce a lot of challenges like overlap planning and flight height restrictions. I would recommend free flying it slowly and getting more images that you think you need. It might take a couple of tries to figure out exactly what you need.

What are the recommended settings for the camera as far as the following:

Style?

Sharp/Saturation/Contrast?

Those settings are user settings and are left up to the user's taste and survey area content. They don't really affect processing very much.

As of today version 2.1.0 is available with the Terrain Awareness feature. This feature keeps the aircraft a uniform distance from the ground to keep the GSD and overlap consistent. It enables high quality mapping of areas that are not flat.
