    • Abstract
  • The methods for the transformation of map digitized coordinates to ground coordinates include conform method,affine method and project method.Based on these transformation methods,map digitized data are processed by transforming these data into the ground coordinates.And these coordinates are treated as independent observations with the same accuracy.Several schemes of map digitized data adjustment are presented.The results are then analyzed and compared.The influence of digitized data correlation on the adjustment results are further discussed.The accuracy estimation of digitized data is analyzed in the end.
