基于 Android 的小班外业调查系统研建

摘要

For subcompartment survey of forest resources outside the industry survey questions , we discussed the Android operat-ing system that supports GPS in mobile devices PhoneGap platform to build forest resources subcompartment outside the in -dustry survey system technology and methods .We degined a subcompartment survey database structure , OpenLayers Open Source GIS implementation using GPS coordinates acquisition and display , feature editing subcompartment , subcompart-ment elements merge and split , attribute data and spatial data import and export , data format conversion method , and other core functions of the core code .We developed the system to achieve a subcompartment editing , subcompartment correction , subcompartment merge the split , sample editing, and data acquisition functions .%针对森林资源调查中小班外业调查问题，探讨了采用Android操作系统、支持GPS的移动设备中利用PhoneGap平台构建森林资源小班外业调查系统的技术与方法。给出了小班调查数据库结构设计，采用Open-Layers开源GIS实现GPS坐标获取与展示、小班要素编辑、小班要素合并与分割、属性数据与空间数据的导入导出、数据的格式转换等核心功能的方法以及核心代码。设计开发的系统实现了小班编辑、小班纠偏、小班合并于分割、样地编辑、数据采集等功能。
