Complex Geography Shapefiles Make for Confusing Coverage Outputs #527

steesdale commented 5 years ago

When doing planning on a regional level, the shape of the region is treated as a hard stop. In reality, this isn't how people access to care, they may live in one region and travel across.

Also, when visualizing the coverage of a facility - the shape of the region can result in some confusing outputs. See below, where a carve-out region inside a region is excluded, and where the distance between a facility and the selected region shows as no coverage. It took me a second to realize what is going on, but it seems to be skipping over the space outside the region, then picking it back up inside the region. Pretty confusing.
