Scanate implemented in a C program for Linux and Windows

This computer program written in C is an implementation of the idea Scanate. Scanate generates random grid references on a map (eastings and northings) and its name is short for scanning coordinates. The coordinates are then used to see if remote viewing of thes location is possible. Remote viewing is a form of extra sensory perception.
