嵌入式环境下栅格数据访问引擎的设计

摘要

Raster data access engine as an important part of geographic information access engine is responsible for the completion of raster data storage,a library,storage and access.To solve the storage and access in re-source-constrained embedded environments massive raster data,raster maps fast zoom,zoom out,pan and other issues.This article discusses data access engine based on the embedded environment massive raster design and imple-mentation.%栅格数据访问引擎作为地理信息访问引擎的重要组成部分,主要负责完成栅格数据的入库、出库、存储与访问功能.为解决在资源受限的嵌入式环境中海量栅格数据的存储与访问,实现栅格地图的快速放大,缩小,漫游等问题,本文讨论了基于嵌入式环境下海量栅格数据访问引擎的设计与实现.
