| Abstract | ||
| The New generation remote sensing satellites that are being designed to image objects on the Earth’s surface with a resolution of one meter and less. It is believed that such high resolution satellite imaging systems will lead to a paradigm change in mapping science, considering the high resolution, wide spectral range, and stereo mapping capabilities. This will be the first time that users around the world will be able to use satellite imagery to map products on the plane ground at a sub-meter level. This paper presents the results of an assessment of the horizontal accuracy of the new generation of high-resolution satellite imagery WV02 one of the Digital Globe productions for mapping purposes. Based on Evaluation of the planimetric accuracies of Worldview02 Ortho Ready Standard image acquired under a Space Imaging/NASA Data was found the value range to be (1.1 m and 1.55 m) CE90 at test site. The experimental results are very encouraging. It is demonstrated that with two or more GCPs, the sub-meter satellite imagery will have a potential to generate mapping products with a map scale of 1:4,000, which is sufficient for many GIS applications. | ||
