基于GPS的智能农机载高光谱采集系统的初步研究

为了解决精确农业中高密度的和全面的农田信息采集的需要，本系统利用visual basic和map objects对GPS, GIS和RS进行有机集成, 一方面系统通过集成GPS, 能为采集到的光谱数据提供高精度的空间位置属性，实现光谱数据采集、定位和存储一体化; 另一方面通过集成GIS，实现了具有空间属性的光谱数据可视化管理和分析处理, 实时地显示动点轨迹和各图层对应点属性，计算作物微分光谱和植被指数NDVI等功能, 为专家系统和决策支持系统提供充足的信息。

Study on Intelligent System of Hyper-Spectral Data Gathering Based on GPS in Farm Machinery

In order to meet the precision agriculture needs that highly dense and overall f armland information is gathered, this system uses Visual Basic and Map-Objects to carry on integration of GPS, GIS and RS. On the one hand, the system can pro vide the space seat attribute of high precision for the spectral data gathered b y way of integration GPS, and realizes integration in spectrum data gathering, orientation and storage. On the other hand, by way of integrated GIS, the system has realized the function of visualizing analysis and management of the spectr um data, displaying real-time trace of moving point, providing some related att ribute of the moving point in map layers, and calculating crop derivative s pect ra and crop vegetation index NDVI etc. The sufficient information is put forward for expert system and decision support system of precision agriculture.
