DGPS-Based nationwide highway surveying in china |
| |
| Abstract: | Several key problems are discussed in the paper,which occur in the data collection of the vehicle carried DGPS highway surveying.The pooblems than how to obtain the data by field data collection,which includes GPS highway surveying data and attribute data of terrestrial objects and also the data of time-matching between them ae resolved.The problem of obtaining highway vector-data with DGPS by data processing in the office is also resolved.The integration of vector-data and attribute-data can be resolved by the attribute matching of terrestrial objects,which are the basic Data of Geo-scientific infrastructure. |

| Keywords: | DGPS differential correction of pseudo-range attribute of terrestrial objects time-matching highway surveying |
