General description

Overview of Challenge

5

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

In countries such as South Sudan, cost of developing infrastructure can be highly influenced by the need to excavate through soft ground.  Black cotton soils (vertisols) are especially prevalent and the cost of developing through areas where they dominate can be very challenging.

6

Thematic information requirements

11. Determine lithology, mineralogy and structural properties of the near surface,

7

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

Increased development costs, subsidence of infrastructure

8

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

Extensive excavation, route planning to avoid these areas

9

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

Imagery to reduce time taken to identify these areas would be useful. Areas identified as historically subsiding can be identified where past data already exists.

10

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