Advanced GIS Name: Arnob Rahee HOA 2: How to Use Remotely Sensed Imagery in ArcGIS Pro Question 13.1: (1 point for undergrads, ½ point for graduate students) What features of this building as seen from the sky in this orthophoto would help you to identify it as the Rock and Roll Hall of Fame (or at least a unique building dedicated to music)? The pyramid shaped glass attached on the side of the building. Question 13.2: (1 point) What four different outdoor sports does Humphrey Park accommodate? Which elements of image interpretation are used to determine this and how are they used? BasketBall, American football, Tennis and baseball. There are 2 basketball shaped stadiums There are 2 tennis shaped stadiums One stadium designed to play American football 4 baseball stadiums Question 13.3: (1 point) What type of development (residential, industrial, commercial, etc) is to the immediate north and northeast of Humphrey Park? Which elements of image interpretation are used to determine this and how are they used? The area to the immediate north and northeast of Humphrey Park is commercial development, as indicated by the regular grid-like structures Question 13.4: (1 point: Challenge Question: Required for graduates students, but worth an extra credit point for undergrads who get it correct) This facility shown in the orthophoto comprises many different things but they all contribute to one overall place. What kind of facility is being shown in this image? Which elements of image interpretation are used to determine this and how are they used? It is a park. Open spaces and the trees proves that this is a park. Apart from this the place has desalination plant. The fact that this place is close to sea and also for the fact that this place is very open as a google search reveals that “Desalination plants are often built near the open ocean because the concentrated seawater mixes quickly with the surrounding seawater”
Question 13.5: (1 point for undergrads, ½ point for graduate students) What kinds of details of the harbor and the boats can you see in the 0.3-meter orthophoto that you cannot in the 1-meter NAIP image? Why is this? The color of the boats and that of the water is much detailed in 0.3 meter harbor than in 1-meter NAIP image The detailed color variations in a 0.3-meter harbor image compared to a 1-meter NAIP image result from differences in spatial resolution. A 0.3-meter image has smaller pixels, capturing finer details, while a 1-meter image with larger pixels loses some nuances, leading to reduced color and feature differentiation in the latter. Question 13.6: (½ point) Why do the trees look green in the NAIP Natural Color image but look red in the NAIP Color Infrared image? Hint: keep in mind which bands are being shown in which of the three channels, and the properties of those wavelengths. In the NAIP Natural Color image, the green appearance of trees is due to the combination of visible light bands, emphasizing the green color of chlorophyll. In the NAIP Color Infrared image, near-infrared (NIR) replaces the red channel, highlighting healthy vegetation as red since plants strongly reflect NIR light, providing insights into vegetation health. Question 13.7: (½ point) Is the field of the Cleveland Browns Stadium real grass or artificial turf? How can you tell from just viewing the two NAIP images? The grass is natural. The redness of the trees and that of the grass is almost same in NAIP Color Infrared image indicating healthy vegetation. Question 13.8: (½ point) Why can you not see individual planes at the airport in the cle.img Landsat imagery? The resolution of the cle.img Landsat imagery is not high enough to distinguish between high Question 13.9: (½ point) At the 30 meter resolution of the Landsat imagery, what features of Burke Lakefront Airport can you still identify? The runway of the airport is distinhguishable Question 13.10: (1 point)
