Abstract: In some aspects, a method for determining a route by an unmanned aerial system (UAS) is described, the method including: receiving at least two locations, a first location and a second location; receiving UAS characteristics and spatial data; outputting a map based on the UAS characteristics and the spatial data, the map indicating a fatality rate; and outputting the route for the UAS to fly from the first location and the second location based on the map indicating the fatality rate. In some aspects, the spatial data can include at least one of: a social media activity; a density population; an area of one or more buildings; and a height of the one or more buildings. In some aspects, the route can be configured to be modified in response to at least one of safety or urgency.
