摘要
为提高森林火灾风险普查的工作效率,保证数据成果的准确性,分别介绍了利用GPS、RS获取外业调查数据以及利用ArcGIS获取内业矢量化数据的方法,总结了 3S技术在森林火灾风险普查工作中调查可燃物、重要火源点、森林火灾减灾能力以及内业图件成果编制方面的经验,且针对工作中遇到的实际问题进行了讨论,为今后3S技术应用于其他林业调查提供参考.
Abstract
In order to improve the efficiency of forest fire risk survey and ensure the accuracy of data re-sults,the paper introduced the methods of using GPS and RS to obtain field survey data and using Arc-GIS to obtain indoor vectorized data respectively,summarized the experience of using 3S technology to in-vestigate combustibles,important fire source points,forest fire disaster reduction capabilities,and prepare indoor map results in forest fire risk survey,and discussed the practical problems encountered in survey,providing reference for the application of 3S technology in other forestry investigations in the future.
