根据农田小气候环境监测的特点,分析了利用多传感器采集的小气候环境参数的时间、空间分布特性。针对小气候环境监测环节中对地理空间分析和数据可视化的具体需求,研究了农业物联网信息感知、物联网资源与地理信息系统(GIS)融合、感知数据可视化等技术,建立了物联网资源与GIS融合的统一接口规范,并以GIS为基础,设计了多种可视化方法对采集到的多维小气候环境数据进行同步展示和可视分析。在此基础上,研发了Web GIS平台,集成了地理空间分析组件、可视化监测服务组件和基于地理位置的智能移动端应用。实现了基于GIS的农田小气候环境可视监测系统,通过不同终端设备提供可视监测服务,方便农业参与者随时随地掌握农田的小气候环境。

GIS Based Visual Monitoring System of Farmland Microclimate Environment

The microclimate environment monitoring is significant for agricultural production. Several characteristics of microclimate environment monitoring can be summarized from a variety of monitoring systems. Particularly, environmental data collected by multiple sensors have shown temporal and spatial properties simultaneously. The need for geospatial analysis and data visualization in monitoring microclimate environment became the main focus. In order to achieve this, a certain kinds of techniques were explored including internet of things (IOT) perception, the information fusion and data visualization. Furthermore, a unified interface specification was established to fuse IOT data with geographic information system seamlessly. In order to display and visualize the multidimensional environmental data, a series of visual methods were developed. Moreover, a web geographic information platform was built by using the Baidu Map APIs. In addition, several components were implemented including the geospatial analysis component, visual monitoring component, and some location based mobile applications. Finally, a flexible and vivid visualized monitoring system was formed. The adoption of this system could make it more convenient and easier to visualize and understand the microclimate environmental conditions via different terminal equipments.
