Horizontal Accuracy Assessment of High Resolution Satellite Imagery forMapping Purposes

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.
