Real-world Problem: After disasters like earthquakes, tornadoes, hurricanes, etc. search and rescue teams employ wide-area search techniques. In a wide-area search, it is important to be able to assign areas to teams to search every house and road. However, it is difficult to actually assess the search progress in a quantitative way.
Technical Problem
Part I: We would like to count the number of buildings that have been searched in an area by using looking at the number of buildings that do/do not have a waypoint on them (from Survey123).
We have figured out how to count buildings so far using this very handy expression...
