基于天地图在线瓦片拼接制图技术研究

Research on Cartography Technology of Tile Splicing Base on TianDiTu

为扩展地图编制、科学研究空间数据来源,同时丰富天地图应用场景,本文提出通过拼接天地图在线瓦片数据以及空间配准等技术流程处理,实现天地图大范围高清数据的获取和应用。测试实验中,以长沙市梅溪湖地区的影像对本算法和流程进行了应用测试,结果表明,本方法技术路线科学,拼接成果图片信息准确。

This paper allows us to expand into the sources of spatial data research and enrich the set of application scenarios by clipping the Tile of TIANDITU.The experience with the image of Meixi Lake in Changsha City shows that the technical route of the method is scientific and the image information of the splicing results is accurate.
