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.

TL;DR: In this article, a laterally constrained inversion scheme for continuous resistivity data based on a layered earth model (1D) is presented, where all 1D data sets and models are inverted as one system, producing layered sections with lateral smooth transitions.
