    All of the simple spatial relations have been implemented: North, South, East, West, and In. In addition, the following spatial relations have also been implemented: NorthEast, NorthWest, SouthEast, SouthWest, InPerimeter. North, South, East, and West all depend on the minimum bounding rectangle. Any of these directions is defined as the exact space of the MBR, but not going beyond the edges. For example, North is defined as myY < mbrMinY, but with two constraints myX <= mbrMinX, and myX <= mbrMaxX.

This way, North is not defined loosely as some degrees left and some degrees right. For this latter purpose, the four previously mentioned additional spatial relations have been introduced to provide some more precision.

The function InPerimeter is used to denote that the person is in the minimum bounding rectangle of a building, rather than being inside the building. This becomes important when dealing with L- or U- shaped buildings, or even buildings with enclosed yards.

The non-filtered output of all spatial relations is printed in the second of the four text frames. The order in which the output appears corresponds to the distance between the point selected on the map and the centroid of the buildings, starting with the smallest and going to the largest distance.
