We use 'Move' from Midland Valley as the core software for cross-section construction and structural modelling. The software is used to create viable cross sections within regional or detailed scenarios.
The sections require mapping using both image data and, importantly, excellent quality DEM data from SRTM, SPOT HRS or better, for regional and detailed levels respectively. The recent availability of 5m DEMs from either satellite or airborne systems, using both optical and radar sources, has allowed DEM data to match the higher resolution image datasets now available.
We use the DEM to perform dip analysis. From SPOT or more detailed DEMs, the classic three-point algorithm has been developed to provide better dip control where data allow. Where measurement is not been possible, due to obscured or indistinct bedding, then qualitative dip symbols are used, showing flat, gentle, moderate, steep or vertical bedding.
The technique is especially useful to link structures that have been interpreted on widely spaced seismic data. The satellite data provides interpolation between lines that allows accurate linkage from one line to the next.
There are a number of advantages to our modeling service:
A world-leading supplier of satellite images, multi-client products and bespoke mapping services.
Geological mapping and interpretation of remote sensing data, from regional projects to detailed interpretation of licence blocks.
