A JavaScript library that performs coordinate transformation between two plane coordinate systems using transformation definitions generated by Maplat.

Maplat is the cool Historical Map/Illustrated Map Viewer. It can transform each map coordinates with nonlinear but homeomorphic projection and makes possible that the maps can collaborate with GPS/accurate maps, without distorting original maps.
