摘　　要：ArcGIS for Android(AA)技术作为新型移动电子地图技术具有功能丰富、定制性强、数据类型多样等优势,极大扩充了移动电子地图的应用场景。针对AA技术注记功能中无效加载量多、注记相互遮盖、要素类型限制的问题,该文提出了一种基于AA技术的移动端电子地图动态注记新方法。通过窗口搜索和4分区筛选两个主要步骤,实现多余要素过滤与注记均匀分布。同时,从遮盖性与加载效率两方面设计实验进行分区因子影响对比分析,验证了该方法的正确性与可行性。ArcGIS for Android（AA）is a newly kind of mobile electronic map technology which is characterized by multi-functions,robust customization,data type diversity and enormously expands the application field of mobile electronic map.Aiming at the excessive invalid load,lettering mutual occasion and feature type constraint of lettering functions in AA technology,a new method of mobile electronic map dynamic lettering based on AA technic was proposed.Redundant feature filter and lettering uniform distribution were achieved by window searching and quarter section selection.At the same time,correctness and feasibility of this method were verified by section factor influence contrast experiments from the aspect of occasion and loading efficiency.
