摘要
把低空航摄获得的地面影像速配到已有的GIS系统内,有助于提高地理空间信息更新的工作效率,具体而言,这主要取决于影像空间关系变形的校正处理,以及与GIS图层坐标系之间快速而准确匹配的可能性。改进此两方面的关键技术,对于加快地理空间信息的自动更新,将会起到明显的促进作用。
Its updating efficiency of geo-spatial information would make an great progress with these images from aerial survey to be put into Geographics Information system(GIS) in time, moreover, there are two key techniques about geo-information orientation and identification, i.e. ( 1 ) how to correct these anamorphic images of aerial survey, and (2) how to put the images into GIS. The geo-information updating affairs may profit from improving these automatic techniques.
