Discussi on about double half-thread reading in measurement of sight lengths by theodolite |
| |
Abstract: | The paper discusses whethter the doubled half-thread reading value read from a theodolite can be taken as a sight-length. After strict derivation in math the mathematic model error value of between the doubled half-thread reading and the full-thread reading is achieved; comparing the drawn error value curve with the accuracy of aurveyed sight-length numbers the paper gives clear conclusions and suggestions. |

Keywords: | sight-length theodolite doubled half-thread |
