摘要
基于JSON语言的灵活和可跨语言传输等特性,描述了地理信息数据的自适应压缩传输的具体方法及步骤。选取实际的地理区域,获取该地理区域中的地形、植被和水系等信息,建立地理信息对照表;并通过对该区域的离散采用、栅格数据字典构建、压缩、Base64编码、传输和接收解析等操作,验证了地理栅格数据的自适应压缩传输方法的可行性。
Based on the flexibility and cross language transmission of JSON language,the specific methods and steps of adaptive compressed transmission of geographic information data are described.By selecting the actual geographic region,and obtaining the terrain,vegetation,water system and other information in the geographic region,the geographic information comparison table is established.And the feasibility of the adaptive compression transmission method of geographic raster data is verified by the operation of discrete adoption,raster data dictionary construction,compression,Base64 coding,transmission and receiving parsing.
