The invention discloses a remote sensing technology-based land surveying and mapping system, which comprises a land basic information acquisition module, a precision data processing module, an image analysis processing module, a comprehensive identification processing module and a surveying and mapping information output module, and relates to the technical field of remote sensing surveying and mapping. According to the method, the technical problems of missing detection, false detection or discontinuity when the boundary in the image is identified are solved, through double screening of similar image judgment and boundary correlation verification, it is ensured that only effective image pairs containing the land boundary are reserved, boundary complementation is achieved through a double-image boundary fusion algorithm, and missing detection of a single image is avoided; the contour is optimized in combination with the parameterized Canny algorithm, compared with existing pure edge detection, the boundary burr removal rate and the shape fidelity are improved, curvature screening and distance constraint strategies are adopted for key inflection point extraction, core features are reserved while redundant points are removed, and the boundary point set precision is improved.

This invention discloses an adaptive wellbore correction method based on a wellbore response database, belonging to the field of geophysical logging technology. This adaptive wellbore correction method, based on a wellbore response database, is applied to actual logging data from the small-diameter array induction logging instrument HACRT. For wellbore impacts with intrusion, a wellbore correction model with intrusion is introduced. The intrusion impact is calculated using geometric factors, and the wellbore response is calculated using the wellbore response database to obtain a logging response estimate. This invention solves problems such as skin effect correction of the wellbore model response signal, inconsistency between the wellbore model and the actual logging environment, and multiple solutions in wellbore model parameter inversion. It considers engineering problems in actual logging data processing and is adaptable to harsh well conditions such as larger well diameters and low-resistivity salt-cement slurries.
