摘要
研究瓦片金字塔模型和四叉树技术基础上,提出了一种地理地图栅格数据模型,该模型将地图栅格数据的使用分为获取、组织和索引三个步骤,并分析研究各步骤主要技术和方法,并利用瓦片金字塔模型和四叉树技术完成栅格数据组织。该模型能够高效完成栅格数据的组织和其他操作,具有高效实用特点。
On the base of the research of tile pyramid model and the quad-tree technology, a geographic map raster data model is proposed, which uses the map of raster data with three steps that capture, organize and index, and each step of ma- jor techniques and methods is analyzed, and tile pyramid model and quadtree technology are used to complete raster data or- ganization. The model can efficiently complete raster data organization and other operations, is efficient and practical.
