基于ArcMap的电子地图瓦片制作方法

Method for Making Electronic Map Tiles Based on ArcMap

介绍了采用ArcMap生产“天地图·南昌”电子地图瓦片的数据处理流程,配图以及瓦片切片的技术,其中包括POI数据预处理、数据脱密、数据抽稀、符号库及配图模板制作,地图瓦片切片等步骤,最终实现了POI数据在电子地图中科学、合理、清晰、美观地表达。在制作的过程中,总结了POI数据处理及抽稀的经验及方法,提高了电子地图编制的技术水平,为类似电子地图项目的生产制作提供了一定的技术参考。

This article introduces the data processing flow,map matching and tile slicing technology for the production of"Tianditu·Nanchang"electronic map tiles using ArcMap.Including POI data preprocessing,data decryption,data thinning,symbol library and map template production,map tile slicing,etc.Finally,the scientific,reasonable,clear and beautiful expression of POI data in the electronic map is realized.In the production process,the experience and methods of POI data processing and thinning were summarized,which improved the technical level of electronic map compilation,and provided a certain technical reference for the production and production of similar electronic map projects.
