Introduction

Basic geographic information is an important basic and strategic information resource in the construction of national information, and it is the unified basis of geographical elements. And space carrier, mainly including digital orthophoto data, terrain feature data, digital elevation model data, topographic map data. National economic construction, national defense construction and rapid social development, the basic geographic information data of the normative, integrity, current situation put forward Urgent requirement. This standard for the provinces, autonomous regions and municipalities 1. 10000 basic geographic information status, taking into account the production, building, more New and distributed service requirements, the 1. 10000 terrain factor data are co-ordinated and maintained with other national scale terrain elements According to the convergence, in order to achieve the national series of basic geographical information linkage update and collaborative services to lay the foundation.
