Spatiotemporal relationships

tContains({geometry,tquadbin},{geometry,tquadbin}) → tbool
tCovers({geometry,tquadbin},{geometry,tquadbin}) → tbool
tDisjoint({geometry,tquadbin},{geometry,tquadbin}) → tbool
tDisjoint(th3index,th3index) → tbool
tDisjoint(ts2cell,ts2cell) → tbool
tDwithin({geometry,tquadbin},{geometry,tquadbin},float) → tbool
tIntersects({geometry,tquadbin},{geometry,tquadbin}) → tbool
tIntersects(th3index,th3index) → tbool
tIntersects(ts2cell,ts2cell) → tbool
tTouches({geometry,tquadbin},{geometry,tquadbin}) → tbool

The temporal form answers a tbool that carries the result at each instant, where the ever and always forms of the previous section answer a single boolean over the whole time span. An H3 or S2 cell is related as the temporal geography of its boundary, which has the temporal disjoint and intersects relationships between two temporal values, so two cells of the grid are related on the sphere.
