Frequently Asked Questions

Please find the answers to the most common questions below. If you cannot find your answer, please do contact us.

General questions

  1. Why are you doing this?
    We are trying to build an accurate map of the area around the Fawley refinery to be able to run computer simulations of the evacuation process should an emergency occur at the refinery.
  2. Why Fawley?
    Fawley is the biggest oil depot in the country and one of the most complex in Europe. Hence it is important to ensure we have the best emergency plans for this area.
  3. What research are you doing as part of this exercise?
    We are trying new crowdsourcing technologies where large large numbers of tasks are executed by large numbers of anonymous users, essentially a crowd. We are testing whether the workflows we've built work and how humans react to the interfaces given to them.
  4. Who is funding this research?
    We are a group of University of Southampton researchers funded by the Engineering and Physical Sciences Research Council and, in particular, by the ORCHID Programme.
  5. What are the lottery prizes?
    There are eight lottery cash prizes:
    • £300 for the first prize
    • £200 for the second prize
    • Six prizes of £50 each for runners up
    In addition to the above, there is a separate £100 for the top contributor (i.e. the one who completed the most tasks). Please note that Orchid team members are not eligible for these prizes.

About the tasks

  1. What will you do with the map we generate?
    We will first remove errors, compile a high-resolution version of the area and then produce a map for 2D computer simulations that will allow us to simulate the movement of thousands of people in an area.
  2. What do I gain from doing a task?
    You win a lottery ticket for every set of 10 tasks you perform that are considered to be correctly performed (i.e., not randomly drawn!).
  3. What if I draw random routes and/or buildings?
    Your contributions will be checked and verified by your fellow contributors. Therefore, inaccurate results will be flagged up and subsequently removed.
  4. Something wrong with a task?
    If you have a problem doing a task (e.g. there is no visible building to draw), you can skip the task by using the Another Task button at the bottom of the page. There is also a Feedback button to inform us about any issue with the task. Your feedback would be greatly appreciated as it help us improve the website.
  5. Why is the aerial picture I see different from the street-view picture?
    This is because GoogleMaps pictures are older than street-view. With more up-to-date pictures, better mapping will be possible. For now, please let us know when you see such occurences using the feedback button and we'll do our best to correct our data for them.
  6. Why don't you use Ordnance Survey (OS) Maps?
    OS provides building and road network data but not the actual connections from buildings to roads. Which is why we've built CollabMap. We still ask users to draw buildings as the OS building coordinates cannot be given out to everyone for free.
