We agreed on a method that we think may be the most efficient in capturing data. We chose to build a square to bring to the stream for pictures. The square within the pictures can then be used to mark horizontal and vertical lines in Hugin which performs a perspective correction. This idea was based largely off the tile sqaure "river" we made in the lab. We found some wood, screws, and metal supports to construct the square. I'm excited to do a trial build and then take our creation to the streams to see if this method will work.
