Ok I have all of the POI for white orchard loaded in the DB. Now that I can see everything my points are off.

It turns out that Wither 3 Map web uses a library that uses coordinate system that accounts for the curve of the earth. The map is flat but by hand placing the points for the map they are sort of behind a wall of trig and ellipsoidal projection:

So I need to write a converter/un-projector both directions for the Geo projection mapping system "WGS 84 Web Mercator EPSG:3857" then they will line up perfectly. lol :(
