Challenge Description |
||||||||
What is not possible / not adequately addressed at present? |
||||||||
Need to improve identification of duricrusts and weathering profiles to assess rock excavability.
|
||||||||
What effect does this challenge have on operations? |
||||||||
Reduces uncertainty, improves decision making for field development. Early identification of constraints and opportunities. |
||||||||
Thematic information requirements: |
Ortho base images Lithology, structural geology, surficial geology Terrain information Topographic information |
|||||||
What do you currently do to address this challenge? How is this challenge conventionally addressed? |
||||||||
Geotechnical Desk Study Ground investigations and boreholes Geological maps Field geological mapping Geophysics Remote Sensing (multispectral) analysis |
||||||||
What kind of solutions do you envisage could address this challenge? |
||||||||
DEM analysis High Resolution stereo DEM Multispectral and hyperspectral Automated classification processing Geophysics |
||||||||
What is your view on the capability of technology to meet this need? Are you currently using EO tech? If not, why not? |
||||||||
Best suited to use of high resolution optical imagery and high resolution DEM. Currently only rarely used because of perceived high cost. There is a need to educate industry to the cost-benefit value of using this data early on in project lifecycle - data |
