基于开源项目的林业资源数据采集Android移动应用构建
|
摘要
为适应林业资源数据采集的多样性和减少授权费用的问题,探讨采用Android的智能移动设备中利用开源项目构建林业资源数据采集应用的技术与方法。给出应用的功能规划、工作流程、应用的实现方法和关键代码。设计不同表单采集不同数据;采用osmdroid作为GIS引擎,叠加显示多种图源的地图数据,并实现空间数据的编辑;Spatia Lite作为存储基于空间定位数据的存储方案;使用模块化开发的林业资源数据采集应用可实现空间数据的编辑,以及基于空间定位的不同数据的采集。
For the diversity of forestry resource data collection and reduce the cost of authorization,the technologies and methods of using open source projects to build forestry resource data collection applications in Android smart mobile devices are discussed. The application of functional planning,workflow and application of the implementation method were designed. Designing different forms to collect different data. Taking osmdroid as the GIS engine,superimposed display map data of a variety of map sources,and achieve spatial data editing. Using Spatia Lite as a storage solution for storage based on spatial positioning data. The forest resource data collection Android app using modular development enable spatial data editing,as well as acquisition of different data based on spatial positioning.
