| Abstract: | GeoEye-1 satellite is an important milestone during the development of images with high-resolution,and GeoEye-1 satellite sensors adopt three-line array CCD scanning sensors,what's more,it has a good many advantages such as high-spatial resolution,large ground coverage area of single-scene.Using the parameters of RPC model which the image possessed itself can do the ortho-rectification and three-dimensional mapping easily.The paper took Hobart(a city of Australia) as an experiment area,and the experiment studied the precision and error distribution of DOM produced from GeoEye-1 images under different condition of terrain and GCPs,which combining the National specifications of aerial surveying with the platform of ERDAS LPS.An objective understanding and evaluation of the accuracy,efficiency,benefit,adaptability and the workflow of DOM produced from GeoEye-1 images was obtained by experiment,and it would provide reliable basis and technical support for DOM produced from GeoEye-1 images. |
