Aerial Triangulation | Part 3: Using Direct Georeferencing for Assisted AT | GeoErnest
Does this mean you use AT for all mapping situations? No it depends on your application, accuracy requirements, and whether you followed procedures. BUT every mapping company should have professional AT software.

Aerial Triangulation | Part 2: Comments from a Viewer | GeoErnest
My expert photogrammetry friend, Josef, has made very important comments about Aerial Triangulation (AT) and Direct Georeferencing for aerial camera mapping.
I thought his comments were important so I decided to make a video about it. Read more of this post

Please come visit me at Intergeo 2012! Say,”HEY! GEOERNEST!” and introduce yourself. I’d love to get to know you. (You could break out into Gangnam style dancing if you want. I’ll join you if you do.)
I’ll be in Hall 9 – Booth no. 9E.62 – Trimble.
I’ll be wearing grey suits with bright red or pink handkerchiefs. Then we can have nerdy geo- talks about best practices, current technology, and future trends.
Mmm…Nerdy goodness.
