| Abstract: | Some problems, such as the difference between interpolation accuracy and extrapolation accuracy, accuracy estimating of translated n＇ormal height, evaluating on height elass of GPS-Leveling and so on, are discussed. By use of a set of GPS-Leveling data, moving weighted average and moving polynomial function and corresponding methods with earth gravity model are compared. At the end, advice for how to choose the best moving method is given. |
