| 摘 要： | 本文以乌兰布和沙漠的遥感影像中白刺沙丘为研究对象,利用ENVI和ArcGis软件对其进行地物边缘提取。通过对比提取后的白刺沙丘形状和外业调查数据,发现其吻合效果较好。又通过对其测量精度验证,检验其有较高的提取精度。通过利用ENVI和ArcGis提取乌兰布和沙漠遥感影像中白刺沙丘边缘的研究,目的是为利用遥感影像提取沙漠地区植被的调查提供参考和技术支持。

| Abstract: | Based on ENVI and ArcGIS software,the particle attempts to make terrain edge extraction for nitraria dune in remote sensing image from Wulanbuhe Desert.It has good anastomosis effect compared to the field investigation data.After the verification for the measurement accuracy,it proves to be high extraction precision.The purpose of the particle is to provide technology reference for the extraction of vegetation from the desert using remote sensing based on the research on terrain edge extraction for nitraria dune of remote sensing image of Wulanbuhe Desert. |
