Q: Is there a way to query if a given point is inside a polygon (closed area)?
A: Yes, with v.select. It allows you to select points which overlap areas or vice versa:
v.select ainput=points binput=areas output=points_in_areas
The resulting map 'points_in_areas' will contain points which are inside the area(s).
