It should be possible to calculate the distance between things on the map. Of course, this will be an approximation depending on how it's implemented. If you take a straight line between two treasures, it won't account for the 3D terrain between those points. But an approximation could still be useful for estimating things like travel time for a full route through an area. In fact, travel time should probably be calculated by the app using speed values determined from Cheat Engine. You could even allow users to plot a polyline between multiple places on the map so that multiple routes through an area can be compared for efficiency.
