基于TM影像的森林病虫灾害遥感监测系统

利用TM影像可以进行森林病虫灾害的监测,但是操作过于复杂,无法在生产单位进行推广应用。为此,本文根据实际的工作流程,采用ERDAS IMAGINE遥感图像处理软件作为基础平台,设计开发了一个森林病虫灾害遥感监测系统。该系统以安徽省作为示范应用区,依据当地的马尾松毛虫灾害监测经验知识,建立了相应的森林病虫灾害模型,通过输入多时相TM影像,提取灾害信息。系统操作简便实用,较好地实现了森林灾害信息的自动处理,具有很大的实用价值。

A Remote Sensing Monitoring System for the Damage Caused by Forest Insects and Diseases Using TM Images

Using TM images can monitor the damage caused by forest insects and diseases,but its operation is too complex to generalize this technique in production organization.Thus,this paper designed and developed a remote sensing monitoring system on the basis of ERDAS IMAGINE software for the damage caused by forest insects and diseases,according to actual work flow.The system has selected Anhui Province as the demonstration area,established the corresponding model of damage caused by forest insects and diseases according to the empirical knowledge of monitoring local mason pine caterpillar.After inputting multi-temporalTM images,the user can extract damage information.The operation is simple and practical.The system has perfectly realized the auto-processing of the damage information,and been valuable in application.
