Geophysical image integration

 

A powerful feature of LIME is the ability to import geophysical data panels representing 2D sections through the subsurface, such as from ground penetrating radar (GPR) or seismic data. The images are positioned in the 3D scene using Panels, allowing them to be overlain on any 3D surface model. This provides a unique ability to directly compare exposed topography with subsurface datasets, to aid correlation, quality control, and presentation of results.

GPR panels placed in the 3D scene, with one panel projected onto a 3D lidar model of an excavated quarry face (courtesy Carbonate Geomodels, IRIS/University of Bergen).

 

Synthetic seismic image generated from orthorecitifed interpretation of photogrammetric outcrop data (Spitsbergen) and used as an analogue for signatures seen in subsurface seismic data from the offshore Barents Sea (Trias North project and collaboration with Isabelle Lecomte, University of Bergen/Oslo).

 

Using the same approach, other types of subsurface data can easily be integrated into LIME as panels. Examples are cross sections through geocellular grids, well log data or core imagery, which can be used to aid characterisation and interpretation of your outcrop, as well as present your results to colleagues and collaborators.

Geocellular grid sections created from LIME outcrop interpretations in geomodelling software, imported back into LIME as Panels for co-visualisation, quality control and presentation purposes (Thompson Canyon (2017), VOG Group, https://v3geo.com/model/9).
