摘要
根据ETM+和DEM等遥感影像数据,运用ENVI5.1软件对ETM+遥感影像进行拼接裁剪,生成江州区遥感影像图,运用ArcGIS10.2对DEM数据进行裁剪,得到江州区DEM数据,提取广西崇左市江州区坡度、坡向、地形起伏度、地貌高程、植被指数等基本地理特征信息,并对地理特征信息进行分析和应用,为广西北部湾经济区崇左市的农业规划、水土流失、地质灾害、资源开发、土壤侵蚀等相关研究提供多方面的空间信息参考.
Abstract
According to the remote sensing image data of ETM +,DEM and so on,automatically clipping and spelling of ETM + remote-sensing image was carried out by ENVI5.1 software,so as to generate remote-sensing image of Jiangzhou District.DEM data were clipped by ArcGIS10.2 to obtain DEM data of Jiangzhou District.Basic geographic information in Jiangzhou District of Chongzuo City was extracted,such as the slope direction,gradient,terrain elevation and vegetation index.Geographic feature information was analyzed and applied,which provides spatial information references for relevant researches of agricultural planning,water and soil loss,geological disaster,resources development and soil erosion in Chongzuo City.
