Integration of vector and raster-based coal mines surface and underground contrast map

Abstract

Through the transformation from the UTM-WGS84 coordinate to the coordinate of our country, we co-registered the remote sensing image and vector map to the same coordinate system, and improved the registration accuracy by using Orthogonal Polynomials and Surface Spline Function. We also adopted the characteristic object display mode to highlight objects of interest. The resulting data were used in WangJiaLing coal mine. The method was applied to coal mine surface and underground contrast mapping and received ideal results.
