Transformation of coordinates at 0.2m level of accuracy.
Derived using 90 stations by IGM Italy on behalf of ASIG. mse = 18cm. Use only for horizontal coordinates; geoid heights must be calculated with ALBGEO3 software. May be taken as approximate transformation from Albanian 1987 to WGS 84 (see code 7834).
