The method of geodetic bridging for high resolution push broom scanner images

A.L. Aksenov, O.I. Kozlov

Pages: 277-282

Summary. In this article a method of use of the digitized linear objects (walls, fences, road trimmings etc.) as basic data for a geodetic bridging of high resolution push broom scanner images is considered. In this method the RPC model for high resolution push broom images (like WorldView, GeoEye) via calculating the linear amendments is developed. The mathematical solution is given. The affine amendments of RPC model for push broom images like Cartosat, Kompsat, SPOT and domestic Resource-P are applied. The example of geodetic bridging for the Resource-P push broom image with the use of well-located linear objects in the territory displayed on the image is presented in article. The result of the method is compared to conventional geodetic bridging on reference points. Control of a refined model with the use of digitized linear objects by reference points is completed. The advantages of digitized linear objects for the planned and high-rise basis are described. The case of an arrangement of linear objects at which the task is solved incorrectly is investigated. Results tables for setting on digitized linear object and tables for assessment of accuracy via control points are provided. Results of experimental application of this method are presented.
