摘要:为满足当今瓦片地图服务中对安全性、灵活性和高性能的需求,弥补当前主流地图服务平台对瓦片地图服务访问控制的单一性,本文提出一种针对瓦片地图服务的多维权限控制策略和控制技术.首先,构建顾及空间范围、图层范围、时间范围的多维权限控制和管理结构;然后,基于多维权限控制策略,利用图像处理、空间计算.NSQL等技术,开发高性能瓦片地图服务中间件,建立瓦片地图服务转发控制体系。结果表明,通过该技术方案能实现对瓦片地图服务的多维度权限控制,保证瓦片数据的安全共享,并提升地图服务的可用性和灵活性。研究成果目前已应用于贵州乱占耕地建房监管平台。
Abstract: In order to meet the needs of security flexibility and high performance in today 's tiled map services, and to make up for thesingleness of access control of tiled map services on current mainstream map service platforms, this paper proposes a muli-dimensionalauthority control for tiled map services Strategy and Control Techniques. First, build a muli-dimensional authority control and managementstructure that takes into account spatial scope, layer scope, and time scope; then, based on the mulidimensional authority control strategy,use image processing, spatial computing, NoSQL and other technologies to develop high-performance tile map service middleware, Establisha tile map service forwarding control system. The resuls show that this technical solution can realize muli-dlimensional authority control ontiled map services, ensure the safe sharing of tiled data, and improve the usability and flexibility of map services. The research results havebeen applied to Guizhou's random occupation of cultivated land and house construction supervision platform.
