GPS与GIS联合进行森林病虫害监测图件制作

我们在进行县级森林病虫害监测时,需制作监测网点位置图,以便在虫害发生时及时察看掌握与准确上报,同时能直观地及时将发生位置等情况同时上报给上级主管部门。如何绘制准确的监测网点位置图件,一直是困绕广大检疫人员的难题。GPS卫星定位仪具有强大的航点记录功能及航迹记录功能,对我们迅速核定发生地点、到达路线及制作相关图件提供了一个快速、精确的手段。本文通过实例,讲述了在GIS系统中利用GPS绘制县级森林病虫害监测网点位置图的方法,供同行参考。

Combination of GPS and GIS on making monitoring maps of forest damage caused by diseases and insect pests

In order to timely observe forest damage caused by diseases and insect pests and accurately report to the higher level authorities about its location, it is necessary to make a location map of monitoring networks in county-level forest damage monitoring. How to make an accurate map of monitoring networks？ This difficult problem has been confusing quarantine inspectors for long time. However, with the strong functions of flight record and track record, GPS provides us a fast and accurate way to confirm the scene and route and make correlative maps. To supply references to craft brothers, this article provides a method of the application of GPS in making a location map of county-level forest damage monitoring networks by instances.
