Function quality and surveying principle of electronic digital level |
| |
| Abstract: | The electronic digital level was pushed out in 1990; its appearing has reformed leveling method to traditional meaning. Its surveying principle is to transform the optical image getting from bar code of leveling staff into digital electronic image and then processes them further. Its advantage is able to avoid the estimation error of surveyor's eye and to heighten greatly surveying precision and work efficiency. |
