摘要
由于田坎数量众多,农作物遮挡等原因,通过外业GPS实测耕地和田坎面积工作繁重。本文提出了基于高分遥感影像提取田坎范围的方法,结果表明:利用高分辨率遥感影像结合GIS软件技术进行耕地田坎系数测算的方法可行,结果可为批量田坎范围提取提供帮助。
Due to the large number of field ridges,crop sheltering and other reasons,the field GPS measurement of the cultivated land and the field ridges were the heavy workload. In this paper,a method extracting the ridge range was proposed based on the high-resolution remote sensing images. The results showed that it was feasible to use the high-resolution remote sensing images combining with GIS software technology to calculate the ridge coefficient of cultivated land. The results could provide help for the batch ridge range extraction.
