General description

Overview of Challenge

5

What is the nature of the challenge? (What is not adequately addressed at present?)

It can be challenging to obtain an adequate exposure analysis (highlighting which hazards endanger the site location), especially in remote areas.

This situation is worsened where there has previously been little or no monitoring in the area.  The identification of geohazards (landslips, seismic movements, etc.) is one element of this.

6

Thematic information requirements

1. Obtain detailed topographic information, 2. Obtain detailed terrain characterisation, 3. Obtain detailed vegetation information,         11. Determine lithology, mineralogy and structural properties of the near surface,   13. Monitor ground movement,

7

Nature of the challenge - What effect does this challenge have on operations?

Being aware of this information i.e. what are the size and frequency of the different hazards?  allows us to quantify the potential damage extent.  Subsequently, this allows us to consider  appropriate actions to mitigate these risks and ensure the safety

8

What do you currently do to address this challenge?/ How is this challenge conventionally addressed?

Existing mapping and recorded data, but this rarely is sufficient - it usually needs to be generated fresh by on the ground surveys.

9

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

Very high to medium resolution exposure analysis based on EO data (impact of floods, impact of landslides, etc.)

Resolution depends on covered area and size of analysis objective

10

What is your view on the capability of technology to meet this need? – are you currently using EO tech? If not, why not?

medium resolution exposure analysis (impact of floods, impact of landslides, etc.)
