【摘要】：森林资源调查是森林资源经营管理的重要工作之一,利用先进的信息化技术进行森林资源数据采集工作能够提高外业调查工作的效率,实现林业调查工作的信息化建设。本文研究在平板电脑上开发了一款基于Android系统能够满足森林资源外业采集工作需求的系统。 本文探讨了采用Android操作系统、支持GPS的移动设备中利用PhoneGap平台构建森林资源外业调查系统的技术与方法。给出了森林资源外业调查的系统结构设计、系统流程设计、系统数据库结构设计,并阐述了系统关键技术实现的具体方法。采用OpenLayers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。设计开发的系统实现了小班编辑、小班纠偏、小班合并与分割、样地编辑、数据采集等功能,开发完成了基于Android的森林资源外业采集系统。本文首次在Android平板移动设备中构建了一个森林资源外业采集系统,在Android系统中利用PhoneGap平台搭建开源WebGIS OpenLayers,并在采集系统中能够使用离线地图。系统能够满足森林资源外业调查工作的业务需求,同时为其他相关研究提供借鉴价值。
[Abstract]:Forest resource investigation is one of the important work of forest resource management and management. Using advanced information technology to collect forest resource data can improve the efficiency of field investigation and realize the information construction of forestry investigation. In this paper, a system based on Android is developed to meet the demand of forest resource acquisition. In this paper, the technology and method of using PhoneGap platform to construct forest resource field survey system in mobile devices with Android operating system and supporting GPS are discussed. The system structure design, system flow design and system database structure design of forest resource field survey are presented, and the concrete methods of realizing the key technology of the system are expounded. OpenLayers open source GIS is used to realize the core functions of GPS coordinate acquisition and display, small class element editing, small class element merging and segmentation, attribute data and spatial data import and export, data format conversion and so on. The system realized the functions of small class editing, small class correction, small class merging and segmentation, sample editing, data acquisition and so on. A forest resource field acquisition system based on Android was developed. In this paper, for the first time, a forest resource acquisition system is constructed in the Android flat mobile device. In the Android system, the open source WebGIS OpenLayers, is built by using the PhoneGap platform and the off-line map can be used in the acquisition system. The system can meet the business needs of forest resource field survey and provide reference value for other related research.
