Abstract:
The all-digital mapping has high precision, fast speed, inside and outside the industry of the integration advantage. With the development of GPS and GIS technology, it has been developed and applied rapidly in recent years. In the multi factor topographic survey, the advantages of all-digital mapping has been fully exploited. In this paper, combined with the large scale a unit research area topographic mapping example introduces several measurement methods of the practical application, and provide reference for similar engineering.
