| Abstract: | In this paper,in order to consider geo-entity encoded in the spatial data updating application as the starting point,the design on geo-entity code were studied.Through the test and analysis to establish a unified set of encoding rules,they can adapt to the data in the production of automatic coding for the elements,and create a favorable technical support for many applications such as the realization of fast positioning and automatic cascade updating. |
