标准图幅下的切片方案管理和展示方法研究

Research on the Management and Display Method of Slicing Plan Under Standard Map

根据瓦片地图切图原理,给出了一套大比例尺地形图的标准图幅切片制作和展示方法,减少了在制作大比例尺地形图切片时对切图软件和专业操作的依赖。文中研究和开发了主流地图API对自定义标准图幅切片的支持,可直接与现有的GIS系统对接,同时利用加密算法对切片文件进行加密,保证了在线标准图幅切片的安全性。通过本文的研究,减轻了地理信息部门在GIS底图制作上的工作量,能够提供多时态、更高效地理信息底图成果。

Based on the principle of tile map cutting,this paper gives a set of standard map slice production and display methods for large-scale topographic maps,which reduces the dependence on cutting software and professional operations when making large-scale topographic map slices.In this paper,the mainstream map API's support for custom standard map slices is researched and developed,which can be directly connected with the existing GIS system.At the same time,the slice files are encrypted using encryption algorithms to ensure the security of online standard map slices.Through the research of this article,the workload of the geographic information department in the production of GIS base maps is reduced,and the results of multi-temporal and more efficient geographic information base maps can be provided.
