Android平台下的地形图图幅信息检索

The retrieval method and system of the topographic map sheet information on android platform

针对当前移动端缺少快速、实时检索地形图图幅信息的系统,本文依据国家基本比例尺地形图分幅与编号标准,提出了基于Andriod平台的地形图图幅信息检索方法并编程实现了该系统。该系统实现的功能有:点所在图幅编号检索、图幅范围检索、地形图新旧编号的转换及区域范围内图幅编号集检索。此系统可应用于Andriod智能手机和平板电脑等移动设备。实验表明,本文的方法和系统执行效率能够基本满足移动用户实时检索地形图图幅信息的需求。

In view of lack of the rapid real-time retrieval method and system,which can retrieve topographic map sheet information on the mobile terminal,according to the national standard of the basic scale topographic map framing and code,the retrieval method and system of the topographic map sheet information on Android platform was proposed and implemented in this text.The system has the following functions：the retrieving of the point where the sheet number;the retrieving of the sheet range;the conversion of the old and the new numbers;the retrieving of the sheet number set of the region.This system can be applied to android smart phones and tablets and other mobile devices.Experiments show that the method and system can execute efficiently and basically meet the needs of mobile users retrieving the topographic map sheet information real-timely.
