  • Hatfield-2201: Identify geological structure through landform

 

 Identify geological structure through landform

Challenge ID:

HCP-2201

Originator:

Onshore: Hatfield

Title:

Identify geological structure through landform.

Theme:

ON 2.2: Surface Geology Mapping - Structural interpretation

Consortium Lead:

Arup

Interviewed Company:

Arup

Geography:

ON.REG.00 - Generic onshore

Challenge Description

What is not possible / not adequately addressed at present?

Information is required to inform structural geological mapping of strata (dip-strike, fold structures). In arid regions, evaluation is more straightforward. In vegetated and tropical areas it is more challenging to acquire accurate classification data.

 

What effect does this challenge have on operations?

In arid regions the evaluation is straightforward. In vegetated and tropical areas, the vegetation means that the underlying surface cannot be observed, which can affect the accuracy of classification.

Thematic information requirements:

Topographic information

Lithology, structural geology,  surficial geology

Land Cover

What do you currently do to address this challenge? 

How is this challenge conventionally addressed?

Field mapping. Multispectral image analysis. LiDAR can be used In vegetated areas to identify landform and structural geology below the vegetation canopy. A spectral library of vegetation type (and seasonal variation) can be mapped with known soil-rock associations.

What kind of solutions do you envisage could address this challenge?

Radar-derived DEM

High resolution stereo optical DEM

Multispectral and hyperspectral images

What is your view on the capability of technology to meet this need?

Are you currently using EO tech? If not, why not?

Satellite imagery  is already well suited, but new technologies coming on stream with increased spatial and spectral resolution (e.g. EnMAP) and new processing techniques will be of benefit.
