SpatialThing
comment:
Anything with spatial extent, i.e. size, shape, or position. e.g. people, places, bowling balls, as well as abstract areas like cubes.
label:
Point
comment:
A point, typically described using a coordinate system relative to Earth, such as WGS84.
comment:
Uniquely identified by lat/long/alt. i.e.
spaciallyIntersects(P1, P2) :- lat(P1, LAT), long(P1, LONG), alt(P1, ALT),
lat(P2, LAT), long(P2, LONG), alt(P2, ALT).
sameThing(P1, P2) :- type(P1, Point), type(P2, Point), spaciallyIntersects(P1, P2).
