Study on Overlaying Remote Sensing Image on Surface- Underground Contrast Plan

Surface-underground contrast plan, as one of the most important engineering maps in the general safety management and production of the coalmine, overlays both topographical map and underground mining engineering plan together, and means to describe the mining area, underground roadway layout, location of working face, rock movement, hydrological distribution, the impact of excavation on the environment and much else during the mining process. Also, the surface-underground contrast plan is a vital evidence for work safety supervision and management department to judge whether the mining activities belong to cross-border mining or unlawful mining or not. However, the data acquisition of terrain on surface-underground contrast plan is very laborious and generally cannot be finished in a short time. Surface changes cannot be embodied on the contrast map in time. In order to solve these problems, a new type surface-underground contrast plan is presented in this paper, in which high resolution RS image replaces the tradition topographical map. After registered by the mining engineering plan, RS image and vector map is fused with each other and provide the richer information on the surface of mining area. The paper mainly concerned about the key techniques and algorithm implementation. Several algorithms was studied and accomplished, including image coordinate transformation, surface spline function calibration, massive image display and characteristic feature highlighted display technique. Programming and testifying have been done. The algorithms were testified by Getting mine, Jining Mining Group, Shandong Provience. The results proved that those algorithms are simple and novel for users. * Corresponding author. [email protected]; phone: +8610 6275 9803;
