I create models from aerial photos taken from a fixed wing or helicopter. Most of my projects are buildings or small rectangular areas and I normally fly in a circle and shoot overlapping oblique images focusing on a point in the centre of the area. I have some projects along roads (see image) that are long and narrow and wanted to get a better idea of the optimal route to fly and collect the images. I am also looking at the best way (flight diagram) to collect images to cover a large area, 15-20 city blocks. I use a hand held camera and can’t take nadir images only oblique Any suggestions appreciated
Have you tried drone harmony app? It shows optimal routes.
Thank for the link Oto. I looked at the user manual and it seems this was designed primarily for automated use with drones; i assume the app controls the camera angle etc. I use a more manual method. I use a fixed wing aircraft or helicopter at approx 1200 feet agl and take th photos manually using a hand held camera, I was looking for some basic information on the aircraft path and the photo overlap that I need for a road corridor. I can only shoot oblique images; the app seems to collect nadir images when mapping corridors.

App shows routes so it is not necessary to use it for automatic flight. You can draw your own shape and check if there is overlap with not only nadir but other plans.

Maybe Bentley could publish their not finished photo planning app even if it doesn't allow automatic flights. It is still announced as existing product - ContextCapture capabilities now include cloud processing services, a mobile app, and photo planning for Bentley’s applications(https://www.bentley.com/en/about-us/news/2017/april/05/going-digital.)
