I have a point shapefile that has all the aerial photos that were flown on our forest. However, they are very old and are black and white. They were scanned by our contractor. Their years are dated back to the 1930's to around 1950's.
I am not really familiar with the photo index and I have been searching around on the internet as I want to learn more about them. I want to know what they are for and how it works.
I have started working on them with my ERDAS Imagine 2016's AutoSync.
My question to you is when I google it, and I have entered the word as flight line or Photo index and it returned few results. Is there a official word/term that should I use to search for more information on google ?
