Introduction
The objective of this lab was to observe the affects of flying at different altitudes had on the image. Each image below was taken at a different altitude. Flying at lower altitudes can be seen as resulting in a more zoomed in image and flying at higher altitudes gives the viewer a wider perspective of the landscape. Furthermore using the attached camera gimbal we where able to adjust the angle of camera to capture more perspectives of the landscape while maintaining a constant flight altitude.
Methods
Flying at incremental values of 10 meters up to 125 meters photos where captured at each increment. Once 125 meters where reached, the camera angle was adjusted by increments of 30 degrees. The purpose of this mission was to evaluate the effect of changing altitudes had on the overall image such as using lower altitudes an alternative to zooming in with a camera and using higher altitudes as a way of zooming out. Likewise the purpose of changing the camera angle was to be able to see how changing the camera angle changed what was captured in the image.
Discussion
By executing this lab we where able to succesfully identify key aspects of UAS imagery in relation to the actual flight of UAS. With that being said we can establish the relationship between altitude and zoom of the photo such that being higher in altitude results in a zoomed out photo with the zoom out increasing as the altitude increase's. Likewise as you decrease altitude we are able to see how flying lower and lower results in a more zoomed in photo.

Figure 2: Taken at 125 meters with camera adjusted 30 degrees from original position.
Figure 3: Taken at 120 meters.

Figure 7: Taken at 90 meters high.
Figure 8: Taken at 80 meters high.
Figure 9: Taken at 70 meters high- At this point the scale of the objects such as the truck as well as the tent and humans are becoming noticeably smaller in the photo. This is a theme that will only continue as we continue to increase the altitude of the UAS.
Figure 10: Taken at 60 meters high.
Figure 11: Taken at 50 meters high.
Figure 12: This photo was taken with the camera facing straight down and at a height of 10 meters. Please not this is also the lowest altitude at which a photo was taken. As a result of the low altitude we have a very narrow field of view and are not able to see much of anything other than the ground.
Figure 13: Photo was taken at 20 meters high and we are able to see some more details of the surrounding enviornent come into play such as half of a truck. This is where we can start to begin and see the relationship between the altitude a photo was taken and the field of view in the photo.

Figure 15: Taken at 40 Meters high- It is at this point where we are able to identify the full truck along with the multiple people standing in the field who where also conducting the same mission. Furthermore we are able to identify a shaded tent area that was established for crew members during the course of the mission.
