8. Interpretation#
Interpretation connects reviewed inversion products to geology, hydrogeophysics, uncertainty, spatial context, and defensible exports. These pages define the structure for the detailed step-by-step guide. Station geometry, profiles, and overlays are covered separately in Map Tools.
