General description

Overview of Challenge

5

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

We need to identify areas of floodplain that could become inundated e.g. via flash floods

6

Thematic information requirements

1. Obtain detailed topographic information,  3. Obtain detailed vegetation information,  4. Obtain detailed land-use information,   6. Identify inland water bodies and determine water quality,

7

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

This information can be used in conjunction with, for example, our emergency action plan or the locating of assets or infrastructure

8

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

Out of date or insufficiently detailed basemaps are used.

9

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

High-resolution imagery from optical satellites in combination with satellite radar imagery is used to monitor floodplain areas and identify assets or infrastructure. This can  e.g. support civil defence activities.

10

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

EO could be a useful complimentary technology
