List of images that need making:
1. A pair of comparison maps that have exact mirrors of one of the London maps on here ![[WWW]](/wiki/mstheme/img/moin-www.png){kind=small}
http://www.mysociety.org/2006/travel-time-maps/ , but which is much clearer.
2. A map of SE5 with no contour lines but a black dot and label showing where the maudsley hospital is. This should be the same size as the other SE5 renders you've already done.
3. A House price map for SE5 done somewhat differently from anything done before. Show all isochrones, but make those which are not affordable grey, rather than hiding them altoghether. Use this template: 
4. Same as 3 but using 
5. Same as 3 but using 
6. Add black dot and label showing centre of 
7. Add black dot and label showing centre of 
8. Add black dot and label showing centre of 
NB for 6-8 it would be great if you could experiment with some more contrasting colours than the blue and yellow currently being used. Not sure it is possible, but worth a go!

==Background==
In 2006 Chris Lightfoot produced a series of time travel contour maps, after the Department for Transport approached mySociety about experimenting with novel ways of re-using public sector data.
If you have not seen this previous work it is important that you now take a read through the original page to see what we were building on.
The original maps were very popular online, and the evening standard even published a large article with a copy of one of the maps which covered greater London.
The Department for Transport asked us to show them how this work could be taken further, and that is what we are showing here today.
==Improving Legibility and Clarity==
Many of the maps we produced last time were very pretty, but could be somewhat difficult to interpret. One major task was to read up on how to display such complex and valuable data in more intellible ways, and the results can be seen below.

==House Prices==
Next, it is clearly no good to be told that a location is very convenient for your work if you can't afford to live there. So we have produced travel maps that show not just where someone working can live if they want to get to work swiftly, we can also show what areas they can afford to live in.
To help with this process we picked a real world case study, an NHS doctor working at the Maudsley Hospital in Denmark hill, South London. He's thinking about getting a foot on the property ladder and wants to know where he might be able to live that would both be a tolerable commute, and which he could afford.
First, here's a map showing where the Maudsley hospital is.
Next, we overlay the travel time contours assuming that this Doctor wants to get to work by 9AM. As the key shows, each band represents 10 minutes extra travel time, so the red circle in the middle means he could leave the house at 8.50-9 and still get to work on time. The next band out he could leave at 8.40-8.50, and so on.
Now let's introduce house prices into the equation. Obviously, at first our doctor wants to see what's available at the bottom end of the market, less than £250,000 (the average first time buyer price).
==Car vs Public Transport==
Many people these days are looking to move to public transport, due to reasons varying from congestion, to cost, to environmental impact. But where can you live if you want to have the chance of getting to work speedily?
The following maps show the places you can live in Edinburgh, Cardiff and Birmingham if you want to be on optimal commuting routes for the centres indicated with the black dots.
Remember, these are not general maps for the whole city, each map is only useful for the specific target place of work or study marked with the black dot. Please don't make a mistake and use these to pick your own place of residence unless you happen to work at the location these maps are centered on!
Public Transport vs Cycling
For some people, the dilemma is not between the car and the train, it is between the bycycle and everything else. This maps comprehensively shows that if you live anywhere near the centre of this map, it's best to get on a bike if commuting speed is your main concern.
