摘要在工程生产实践中，经常要处理空间数据，往往会涉及到坐标转换和投影换算的问题。其中典型的就是大地坐标与空间直角坐标的相互转换和高斯投影计算。它们共同特点是计算公式复杂且计算容易出错。常规处理方式是基于计算机编程处理，但缺陷是一旦在准备条件不足或遇到突发问题需要进行坐标换算或投影计算，就可能会导致野外测量作业的终止，降低了生产效率，也不满足现代测绘信息化的要求。42170

根据NetMarketShare网站公布的2015年9月份移动终端操作系统的市场份额排名，Android操作系统的市场份额为53.54%，并继续保持领先。同时，Android具有Linux开源性和可视化编程界面。也正因Android操作系统的广大用户基础和操作以及智能手机移动终端的便携性，本文决定选取以此系统平台进行软件开发，可以轻松实现野外测量、内业数据处理的一体化、智能化和现代化。

这里是通熟悉Java语言和eclipse平台搭建Android环境设计开发测量换算工具的软件应用（大地坐标与空间直角坐标换算、任意投影高程的高斯投影换算）。在整个换算工具开发过程中，包括界面的设计，功能实现，算法的有效执行等一些内容。通过实例验证程序设计的合理性，使之满足工程实践计算精度要。

Urban Subway Operation Stage of Deformation Monitoring Scheme Design

Abstract

In engineering practice, we often encounter the problem of coordinate conversion, especially in Geodesy also relating to the projection problem. The conventional approach is based on the processing of computer programming, but the drawback is that the once in preparation conditions or encounter unexpected problems need to coordinate conversion, it may lead to the termination of the fieldwork and reduces the production efficiency, also can't satisfy the requirements of modern surveying and mapping technology.

According to the NetMarketShare website in 2015 September, the mobile terminal operating system market share ranking, Android operating system market share of 53.54%, continue to maintain a leading. Because of the user base of Android operating system, this paper decided to choose this system platform for software development.

Therefore, fusion based on Android smartphone software of Surveying and mapping, the use of smart phones, portable and flexible, a large number of users can be easily measured in the field, data processing in the industry integration, intellectualization and modernization of.

Build Android environment design and development of measurement conversion tool software applications through the Eclipse platform, comes to earth coordinates and space rectangular coordinate conversion, arbitrary projection elevation of Gauss projection conversion, familiar with Java and Android development environment carrying. In the process of Android development, including interface design, function realization, effective implementation of the algorithm and some other content. The rationality verification program design, to meet the practical requirements of computational accuracy.
