General description

Overview of Challenge

5

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

Access routes can change between seasons as a consequence of flooding, vegetation, etc.

6

Thematic information requirements

1. Obtain detailed topographic information, 2. Obtain detailed terrain characterisation,            14. Obtain detailed imagery of the surface,

7

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

Being aware of these changes allows us to plan our surveys more effectively whilst ensuring the safety of our staff. This also has relevance to identification of areas of soft ground (see challenge OTM:045)

8

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

Scouting team deployed ahead of seismic vehicle, remote sensing, historical mapping (e.g. military maps), online imagery

9

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

Topographical mapping would be important if temporal images are not available.   For seasonal variations you would need to see a collection of images acquired during each season. So for example Lake Chad that can be significantly bigger in the wet season

10

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