野外数据采集是中药资源普查必不可少的工作环节。然而,野外调查内容多,工作量大,再加上野外环境复杂,因此,野外调查工作往往难度较大,调查成本较高。本文设计并实现了中药资源普查野外数据采集系统旨在利用嵌入式技术和GIS技术,提高调查效率和质量。该系统采用4层软件架构模式,实现了地图基本操作、地图导航、图层控制、调查点查看、信息采集等功能,能够为第四次全国中药资源普查野外调查工作提供强有力的技术支撑。
Field data collecting is the essential procedure in Chinese materia medica resources survey. On the contrary, the field survey is usually difficult on the account of both heavy workload and complicate wild environment. Therefore, this paper demonstrates the design and implementation of field data collecting system of the Chinese material medica resources for prompting survey efficiency and quality in using of Embedded technology and Mobile GIS technology synthetically. The system is constructed with 4 layers: data storage layer, I/O communication layer, basic component layer and application layer. It implements basic map operation, path navigation, layer management, survey target management, data collection.
