TL;DR: In this article, a 2D inversion scheme with lateral constraints and sharp boundaries (LCI) is presented for continuous resistivity data, where all data and models are inverted as one system, producing layered solutions with laterally smooth transitions.

TL;DR: SkyTEM as mentioned in this paper is a time-domain, helicopter electromagnetic system designed for hydrogeophysical and environmental investigation, which is a rapid alternative to ground-based, transient electromagnetic measurements, the resolution capabilities are comparable to that of a conventional 40 × 40 m 2 system.

TL;DR: In this paper, a new methodology, spatially constrained inversion (SCI), is proposed to produce quasi-3D conductivity modeling of electromagnetic (EM) data using a 1D forward solution.

TL;DR: In this article, the authors show that for a valley structure in a low-resistive layer, the 1-dimensional assumption is sufficient to track the presence of rather steep slopes, however, the insensitivity of the TEM method to resistors makes it difficult to determine a slope with a 1-D inversion and only the overall structure is defined.

TL;DR: In this paper, the authors present a modular forward response algorithm that is independent of data type, making it easy to add support for new types of data types and instrument geometries.
