georeferencing problem

eamtransit — Tue, 17 Jan 2023 13:21:38 GMT

Good day,

I didn't find a solution yet for a specific problem. I have an area to goereference that consists of 3 images. I am georeferencing with Air Photos 2022 using ArcMap Desktop.

I am able to goereference 1st image however I can’t align 2nd image with 1st images. I need to extract building based on the image. It shows uneven space b/w images (1st and 2nd), (2nd and 3rd)

Shall I combine images (which geoprocessing tool to use). Thanks for your help!

Evan

Not sure why your aerial photographs can not be put side-by-side as a stereo pair? You could just georeference each image separately. Save the control points for each image so you could reload each given image seperately. Sequentially, turn on an image (with the other 2-images unchecked/off in TOC), and add to your GIS all applicable information. Then unchecked/turn-off the 1st image, and check/turn-on the next image, etc... Aerial photographs are images where displacement caused by terrain relief and camera tilt has not been removed.
