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
