At each interval we all took pictures from as many differing angles as possible to capture all four corners and as many control points as possible for our later quantification. Then as a team we lowered down the 8ft by 8ft wooden square and began to place it at three intervals along the 122ft stretch of stream. Then I began the video method wherein I took 15 second videos while walking down either bank. I began to do a photosynth method which consisted of me walking up and down the center of the bank, and up and down the center again first looking at one bank and then the other taking pictures all the while (217 to be exact).

From there we then began to measure distances between the control points in two teams of two and then compared our results which surprisingly enough were spot on for the majority of them. The day began out with a simple task of placing our thirty pre-made and marked control points. Our field day to Blackhawk creek was unlike anything I had expected. Overall, we got a lot of data (suffering some minor aches and pains as the title suggests) and we'll be very busy these last two weeks sorting it all out and hopefully getting some conclusive results to show for all of our hard work! Learning to/determining a common way of using the ruler definitely wouldn't have hurt either, and once again, that's one thing I never expected would cause us any trouble. With all the confusion of trying to sort out the data I wish we would have written some more notes so we could better analyze the data. I learned that you can NEVER take too many notes. Some of the control points couldn't be placed on the water's edge and we needed to brainstorm other ideas on the spot, so being slightly flexible is key. For example, in the classroom, I never thought about the interference of branches at the surface of the water that would hinder data capture or control point placement. Spending the day outside was great, the weather was a little humid but we had lots of shade and thankfully lots of water :) The most important thing it taught me was that you will always learn something new and you may never be able to be fully prepared for research no matter how much thought you put into it. There's just some things that a classroom can't prepare you for and I learned a lot during our field day. Maybe we didn't think them through as well as the others or expected the control points to be on the edge, but either way, we found a solution quickly. The non-photo methods were a lot more frustrating then I had hoped but they turned out a lot better than I expected once we got a system down and started. David and Kyle were busy taking hundreds of pictures to be used in the Photosynth software. In addition to using the square to obtain horizontal and vertical lines, we also placed the square in three different locations and tried to include as many control points in pictures as possible as a means of testing the accuracy of the perspective correction. As with the first practice 'field day' the square method was also utilized but with slight modifications this time.

We used a tripod 'twinning' cameras method to take pictures that could be used to create 3D images of the stream. We used the GPS feature of the camera to get longitude and latitude coordinates of the waters edge on the banks.

When we began planning in the beginning of the term, I never expected that we would have so many different methods to try.
