We flew a project this Saturday that is a typical nadir (looking straight down) mapping project. They also asked for various oblique angle shots of the different buildings and from different angles and directions. When we shoot oblique images the pilot just looks out the window and snaps away.
We have a Canon EOS 5DS R camera that shoots 8688x5792 pixel images (86 Megapixels) and we shoot it all in RAW mode, uncompressed and all the data the sensor has. It makes a 143 MB tif file. It is a huge image.
That much data is more than a good camera like a Hassleblad with an image 2.25x2.25 inches square can capture with film. It is nearing the image quality of a 4x5 frame of film, but not quite there.
When we last used film for the oblique images we shot with a Pentax 6x7cm on professional film. (2.25x2.75 inch) and if we scanned it at the best resolution with out 90 grand scanner it is almost as good as what the Canon does. It just blows me away how far digital has come. Canon is hinting at an even higher resolution camera.
We recently updated our mapping camera and it is a big step up. Faster and way higher resolution.
