ASTER数据在吉林市土地利用调查中的应用

The Application of ASTER Data in Land Use Investigation in Jilin City

以吉林市土地利用调查为例,阐述了以ASTER数据为数据源生产土地调查图件的全过程。同时,简要介绍了土地利用调查的技术方法和工作流程。着重介绍了采用ASTER 15 m空间分辨率遥感影像,参考LandsatETM+30 m分辨率遥感影像,利用1∶50 000土地利用现状图及1∶50 000 DLG地形图,进行影像解译及土地利用统计分类的工作方法。

Taking the land use investigation in Jilin city as an example, this paper discussed the overall procedure of producing land use investigation map using ASTER data. Meanwhile, it briefly introduced the technical methods and working flowchart of land use investigation ,emphatically introduced the working methods for image interpretation and land use statistics classification using 15m spatial resolution ASTER remote sensing image, 1 ： 50 000 land use present map, 1 ： 50 000 DLG topographic map, by taking 30 m resolution Landsat ETM ＋ remote sensing image as reference.
