Gravity and magnetic forward modeling to predict subsurface body effects from observed data.
Run a quick forward gravity model for a rectangular prism on a sample grid and compare terrain-corrected Bouguer anomaly.
High-intent search queries and answers about installing and using this skill.
You compute gravity forward models by defining rectangular prisms and observation coordinates, then applying Harmonica functions to predict subsurface body effects on observed gravity data.
Terrain correction in gravity modeling adjusts observed data for topographic mass variations, and this Skill applies terrain and Bouguer corrections alongside equivalent-source gridding to isolate true subsurface anomalies.
Yes, tesseroids support regional-scale geophysical forward modeling, allowing you to compute gravity and magnetic effects from defined bodies across large geographic areas alongside local prism-based analysis.
Yes, the workflow is compatible with Verde for projections, integrating directly with xarray, numpy, and boule to manage observation coordinates and perform equivalent-source gridding for gravity surveys.
Yes, boule is required alongside Harmonica to perform Bouguer and terrain corrections for gravity surveys, providing the necessary reference ellipsoid utilities for accurate gravity data processing.
The best way to apply equivalent-source gridding to magnetics interpretation data is using the Harmonica ecosystem, which integrates with Verde and xarray to grid scattered observations and perform derivative corrections.
