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 country 1. 50000 basic geographic information status, taking into account the production, construction, update and distribution services needs, 1. 50000 terrain factor data for co-ordination design, and to maintain with other countries of the scale of terrain elements of data convergence, in order to achieve national To lay the foundation for the linkage update and collaborative service of the basic geographic information. Basic geographic information Standard Specification for Terrain Factor Data

3 data description

Basic Geographic Information Terrain feature data is a vector dataset that expresses geographic information elements in terms of points, lines, and faces. The point element is represented as one Coordinate elements and corresponding attribute values; the line elements are represented as a series of coordinate tuples and corresponding attribute values; the surface elements are represented by the first and the next A string of coordinate tuples and corresponding attribute values. 1. 50000 terrain factor data is the main component of national basic geographic information, including positioning basis, water system, residential area and Facilities, transportation, pipelines, realm and politics, landforms, vegetation and soil, toponymic 9 categories, widely used in national economic construction, national defense construction And social development and so on.
