BUT I can't find any tool that allows me to calculate the minimum distance between polygons and indicate the direction of the polygon.
Simon, I see the GEOS library has a Distance() operator that will test the closest distance between two geometries, and also, in the C++ API, a DistanceOp::nearestPoints() method that returns the nearest points on two passed in geometries. From this I imagine you could construct the rest of what you need in a C++ program. While this should be a relatively easy C++ programming activity, I will admit that isn't the same as a user oriented tool.
