采棉机跨区作业导航电子地图的制作

为了使采棉机跨区作业管理中的监控定位更为准确,采用Alos和TM遥感影像、商用电子地图为基本材料,通过对Alos影像进行矢量化并结合外业调查得到作业区域的交通、田块、POI等空间信息图层。同时对TM遥感影像进行监督分类,识别出棉花地块以及面积等信息,在MapInfo桌面GIS软件中对其进行整合得到作业区地图,再与商用电子地图进行图层叠加处理,最后制得高精度、要素丰富、适用于采棉机作业过程中导航定位的电子地图。该采棉机跨区作业导航电子地图使采棉机跨区作业过程中的监控定位更加准确,管理更加有效,既能适应大区域的调度,也能做小范围的作业定位和监控。因此,该采棉机跨区作业导航电子地图的制作方法为制作农业生产应用电子地图提供了技术手段。

Production of the Trans-regional Operation Electronic Map of Cotton Picker

In order to make the monitor positioning more accurate in the management of cotton picker trans-regional operations,with Alos and TM remote sensing images,commercial electronic map as the basic material,the traffic,plots,POI information layers in operation area were obtained through the vectorization of Alos image and field investigation.Then the TM remote sensing images were classified and the cotton plot information and acreage were identified.Using MapInfo desktop software,the above results were integrated to get a map of the operation area,which was then overlaid with commercial electronic map to obtain an elements-rich and high-precision electronic map which could be applied to the operation of cotton picker navigation and positioning.The above method provided technical means for making the electronic maps for agricultural production.
