| Abstract: | Describes the characterstics and reliability of numeral and area measuring instrument determined by Maricoph Judging formula. The presision of area measurement was analysed.A regression relationship between measuring precision and map area was established. The precision of different area measurement was evaluated by regression equation and it was tested with actual measuring data. Thus the allowable error of area measurement was setted. Precautions in using this instrument and improving suggestions was also made. |
