【摘要】：本文针对境外替代种植核查工作的信息采集进行分析,结合GIS相关理论与技术,为替代种植核查信息采集工作设计和开发了一套信息采集系统,以改善现行核查方式、提高工作效率、丰富属性数据采集手段与提高数据准确性。论文首先在现行替代核查业务流程分析和研究的基础上,对系统进行了需求调查分析和可行性研究,对系统数据结构、功能模块划分和总体框架设计方面进行了总体设计；在总体设计的基础上,采用模块化开发的思想,基于Android系统平台,采用ArcGIS for Android二次GIS开发组件、Spatialite空间数据库和百度LBS云服务等技术,运用Java语言在Eclipse平台上对系统进行了开发和实现。系统设计与实现主要包括六大功能模块：基础操作模块、GPS模块、工具模块、图层选择、数据采集和数据管理模块。基础操作模块实现了地图的基础操作(缩放、平移和旋转等)、找点、获取任意点经纬度、基于屏幕的长度测量和面积测量；GPS模块首先对GPS定位进行实现,然后在此基础上实现了基于GPS轨迹的长度和面积测量,最后实现了GPS状态的功能；工具模块提供了多媒体信息获取手段(拍照、录像、录音和草图)和辅助工具(电子罗盘和百度地图)；图层选择模块实现了栅格数据和矢量数据的打开、删除和隐藏功能；数据采集模块实现了基于屏幕和GPS的点、线、面的采集功能；数据管理模块实现了对采集的数据进行显示、删除、更改和删除功能,同时利用百度LBS云服务实现了采集数据的云储存。该系统在替代种植核查工作中实现了空间数据的准确、高效便捷的采集,运用了大量多媒体数据采集手段丰富了属性数据,不仅提高了信息采集工作效率和数据采集准确性,降低了采集失误,而且支持大量的栅格数据和矢量数据进行装载。同时,利用云服务把采集数据进行上传,能够最大限度保证数据安全性。最后从总体设计、详细设计和功能实现方面对论文进行总结,介绍了在数据库和云服务方面的创新运用。针对系统的数据输出、目的地导航和系统稳定性方面等不足之处进行了展望。
[Abstract]:In this paper, the information collection of the overseas alternative planting verification work is analyzed, and a set of information collection system is designed and developed based on the GIS theory and technology. In order to improve the current verification mode, improve work efficiency, enrich the means of attribute data collection and improve the accuracy of data. Firstly, this paper is based on the analysis and research of the current alternative verification business process. The system needs investigation and feasibility study, the system data structure, functional module division and overall framework design for the overall design; On the basis of the overall design, using the idea of modular development, based on the Android system platform, using ArcGIS for Android secondary GIS development components. Spatialite spatial database and Baidu LBS cloud services and other technologies. The system is developed and implemented on the Eclipse platform by using Java language. The system design and implementation mainly include six functional modules: the basic operation module and the tool module. Layer selection, data acquisition and data management module. The basic operation module realizes the basic operation of the map (zoom, translation and rotation, etc.), find points, obtain any point of latitude and longitude. Length measurement and area measurement based on screen; The GPS module implements the GPS positioning at first, then realizes the length and area measurement based on the GPS locus, and finally realizes the function of the GPS state. The tool module provides multimedia information acquisition means (photo, video, audio and sketch) and auxiliary tools (electronic compass and Baidu map); Layer selection module can open, delete and hide raster data and vector data. The data acquisition module realizes the function of collecting points, lines and surfaces based on screen and GPS. The data management module realizes the function of displaying, deleting, changing and deleting the collected data. At the same time, the cloud storage of collected data is realized by using Baidu LBS cloud service. This system realizes the accurate, efficient and convenient acquisition of spatial data in the substitute planting verification work. The use of a large number of multimedia data acquisition means to enrich the attribute data, not only improve the efficiency of information collection and data acquisition accuracy, and reduce the acquisition errors. And support a large number of grid data and vector data loading. At the same time, the use of cloud services to upload the collected data, can maximize the security of the data. Finally, from the overall design. Detailed design and functional implementation of the paper summarized the introduction of the database and cloud services in the innovative use of the system for the data output. The shortcomings of destination navigation and system stability are prospected.
