  I’ve seen this embedded within geographic paths that form polygons. There are many points along each side of a polygon, arranged so that each segment length is longer (1) or shorter (0) than the one before. Decrypts to two floats, offsets from the first point.

    Oh, interesting. What was the meaning of the offsets?

      So, you take the Lat and Lon of point[0] and add the offset vector. This locates with precision, like X marks the spot. We could store an arbitrary path in a database in the clear, and only with a decryption key find a dropped point.
