geo-twd
Conversion from x/y (TWD67 or TWD97) to lat/lon (WGS84). The algorithms and parameters are based on Universal Transverse Mercator coordinate system and Taiwan datums. The 2-degree transverse Mercator of TWD67 is transformed to TWD97 first then transformed to latitude and longitude of WGS84.
