摘要: 针对目前地形量化方法中,量化承载网格层级受限,且量化数据组织管理复杂的问题,提出了一种基于地球剖分网格的四边形网格的地形量化模型。该模型以GeoSOT地球剖分网格为支撑,通过GeoSOT网格编码实现了多层地形量化数据的关联、检索,为矢量数据和规则格网数据的量化处理、组织与存储以及量化数据聚合问题提供了方法。

Abstract: To solve the current problems in terrain quantization, such as the limitation of grid levels, the difficulties in data organization and management, and other issues, a quadrilateral terrain quantization model based on global subdivision grid is proposed. The model adopts GeoSOT as the spatial reference, and realize the correlation and retrieval of quantization data among different layers based on GeoSOT location identification code, which provides methods of the the quantization procession, the organization and storage, the data aggregation of the vector data and regular grid data.

Key words: terrain quantization, global subdivision grid, GeoSOT, data aggregation
