What is photogrammetry? Name several ways in which photogrammetry is classified. Do you believe we are seeing a resurgence in photogrammetry on account of UAS? What are some modern applications of photogrammetry, particularly from the standpoint of other geospatial applications, such as GIS?
Briefly describe the history of photogrammetry and remote sensing? Why is the exploration of such a topic beneficial in a course focused on digital image processing?

What are the two primary classes of aerial photography? What are advantages and disadvantages of each?
Writing in 2014, Wolf, Dewit, and Wilkinson state, “[t]he earliest applications of photogrammetry were in topographic mapping, and today that use is still the most common of photogrammetric activities.” Considering other applications of photogrammetry, particularly in GIS, and the use of UAS, do you think this statement is still true? Why or why not?
Wolf, Dewit, and Wilkinson state that aerial photographs for photogrammetric purposes can be obtained in one of two ways: Acquisition of existing aerial photographs or the purchasing of new coverages. In what ways does UAS image acquisition challenge this? What may be some limitations compared to traditional capture methods?
What are the four major photogrammetric stages according to Schenk (2005)?
