WebSep 1, 2024 · Downward continuation of the gravity field observed on the surface is a method applied to calculate the anomalous field below the surface close to deep sources. However, the downward continuation is mathematically incomplete and uncertain, and its accuracy depends on the sampling rate and coverage of the gravity data. WebDepth information, as discussed and demonstrated in Section 2, can be assessed using various magnetic filters (vertical derivatives, and upward or downward continuation), or estimated using depth to source methods. reference to isles and rankin of interps at different levels and discussion about how to deal with this. cad 閲覧ソフト フリー

WebFinally, the new method was applied to real magnetic data collected using unmanned aerial vehicle aeromagnetic surveys to test on a big car in Southeastern Zhejiang, China. The calculated depth matches with its actual depth. ... We only need to calculate the downward continuation data from the original level to an expected maximum depth level ... WebJul 27, 2024 · Downward continuation is known as one of the crucial steps in interpreting gravity or magnetic data. As the continuation depth and the influence of noise increases, the results of downward continuation become unstable. WebJan 15, 2024 · Satellite and airborne gravity and magnetic data are gathered away from the earth's surface, and the resolution is usually insufficient to describe the geological structures in detail. Therefore, downward continuation is typically used to enhance small-scale sources and improve spatial resolution to interpret potential field data. To further improve … cad 長方形 塗りつぶし
