Three Orientation Translating Algorithm of(Long./Lat.)Coordination and QTM Code Along with Its Criterion Judge of Precision

Based on sumed up the current algorithm between long./lat.coordination and QTM code,a new algorithm called three orientation translating algorithm based on assistant geocentric rectangular coordinate that is used to translating algorithm between long./ lat.coordination and QTM code is presented.At the same time,in order to compare with the differences among the algorithms,a new criterion judge of precision-invert error rate.The result indicated that three orientation translating algorithm not only has good rate and absolute accurary,but also the orthembadism invert error rate is 0.
