OpenGIS网络地图分块服务实现标准(WMTS)分析

Analysis on OpenGIS Web Map Tile Service Implementation Standard

在充分理解OpenGIS网络地图分块服务实现标准(WMTS)1.0的基础上,通过与目前开源社区和商业应用中具有相同定位的几个规范的对比,分析了WMTS所具有的技术特点。分析表明,该规范除支持常规的分块地图服务,还在多图式、多维度、坐标系统适应性以及URL个性化等方面为一些特殊应用提供了有力支持,相应其实现的难度也相对较大,需要实现人员付出更多时间来理解标准的内容。

With carefully digesting the OpenGIS Web Map Tile Service Implementation Standard version 1.0,and comparing with certain peer community specifications,this paper studied the technical features of WMTS and concluded that： In addition to the normal tiled map service,this standard featured in supporting multi-style,multi-dimension,multi-CRS（coordinate reference system） and URL pattern diversity,as a result,it is more difficult to be implemented and so need developers pay more efforts on understanding this standard.
