This week in Photo Interpretation and Remote Sensing we learned more about the types of and techniques for interpreting aerial photography. We were provided background on the types of aerial cameras, the different types of images they capture (oblique, vertical, stereo), the types of film used by traditional cameras, and understand how resolution (spatial, spectral, temporal) applies to aerial photography. We also learned concepts, techniques, and application of visually interpreting aerial photos. We learned about the methods and techniques used to visually interpret aerial photos (i.e. recognition elements). These techniques form the basis for deriving geographic features and/or land use land cover types from aerial photos and that are used in a wide variety of real world applications.
In the laboratory exercise, we learned some basic principles of interpreting features found on aerial photographs. The first map above illustrates ranges of tone and texture for this photo. The second map above demonstrates examples of elements identified, at least partially, by shape and size, pattern, shadow, and association of the surroundings. We also examined a true color image (blue, green, red), identifying 5 areas of color and compared those elements in the same image provided in false color (green, red, and infrared).
We have moved from ArcGIS desktop to ArcGIS Pro and it has been a disorienting week. The changes are vast! location of symbology, labeling, and properties are different, but even the environment has changed to a project oriented system instead of .mdx maps. I am sure I will catch up as soon as I figure out how to control drive location.
