UAV Orthophoto and 3D Digital Terrain Model (DTM)

This is a sample Orthophoto that is a mosaic of a group of images captured using the UAV and techniques described here: http://www.youtube.com/watch?v=01iAJkiFAX0&list=UUNVz08pPZ2XTbAWqAFRlFPA&index=1 I have to thank Mark Willis at http://palentier.blogspot.com/ for doing the post processing for me. Now I know that the imagery I am capturing with my current set up is usable (without using a camera gimbal) so now I need to figure out a method of post processing that will allow me to achieve similar results to what Mark is doing. I am very impressed overall with the progress that the Archaeology field has made in the geo-visualization realm. I'm sure there will be a lot of inquiries into this video and I will be limited in my ability to answer the questions but I'll do my best. That being said, I am now determined to develop a zero cost or very low cost workflow for post processing imagery captured by a small UAV for use in spatial analytics and visualization. I will be continuing discussions on this and other UAV and geospatial technology and visualization topics at http://www.flightriot.com
