IntroductionAIMS:• To state the strategic and operational objectives for the

Teignmouth site (as defined by local managers)

• To rate the chances of success using video-derived information (based on current knowledge) - 4 * rating

* Hopeless (NB star rating is specific to Teignmouth)** Some hope of success*** Good chance of success**** Excellent chance of success

• To suggest a frame of reference for selected strategic and operational objectives

NB Video does not have to do everything! We need to focus on a few viable demonstration examples for each site.

Approach Taken

1) Avoid tackling operational objectives rated at *2) Continue research into operational objectives rated at ** or

above3) Focus efforts and prioritise work on those operational

objectives rated *** or ****

Notice that this approach is reality-driven rather than priority-driven!

But…

Research into new and exciting areas in not halted.

Conclusions

• This approach has allowed us to focus on viable video applications (‘reality-driven approach’)

• Application of the frame of reference is helpful but…- Definitions of operational objectives and CSIs within

the frame of reference are still vague and will have to be tightened up (interaction with local managers)!

- Evaluation and assessment of video-derived CSIs will help to improve the frame of reference definitions and reveal the optimum choice of CSIs.

• The success of the project will be assessed on our ability to demonstrate the utility of video for coastal zone management!

Workshop• How many? Where?

4 workshops centred around the four CoastView field sites

• Methodology:

- We should work together on the content but deliver the workshops independently (avoids language barrier)

• Audience: Range of managers – National scale to local scale, political & technical.

• Content

1. General introduction stating the aims and objectives of the project

2. An outline of what a video is and what it’s capable of, indicating the where appropriate the potential management benefits

3. Give specific examples of the outcomes of the CoastView project showing explicitly how video derived CSIs can assist in the coastal management process.

4. General discussion – centred around the frame of reference.

Action:

We need examples of how video can assist the coastal management process (i.e. make it cheaper, faster, more effective)

We need examples for each site by this time next year!

Proposal that each paper considers:

a) Video-derivation of CSIs currently used by managers’

b) New CSIs identified by the manager where video can help

c) Progress ob Scientific CSIs which may be useful to managers in the future
