London building outlines homework assignment

Posted by Harry Wood on 7 September 2009 in English (English)

I've set a homework assignment for the London Mapping Party a week on Wednesday. Time to sort out those building outlines!



(brightbuildings style)

If it looks like I'm starting to run out of ideas for London mapping parties... it's because I am. However this is one thing I have been meaning to experiment with for a while. A tweak to the normal mapping party format, as an attempt to tackle some of the problems of detail level in Central London. We've been doing pretty well at scattering node features everywhere recently, but as I've already mentioned landuse around Marble Arch is bugging me, and building outlines are even worse. Some parts of London now have lots of building outlines drawn in. On the one hand they're making the map look beautiful in these areas, but on the other hand they create a rather ugly imbalance. The solution is obvious, and delightfully inevitable. We have to map 'em all!

Not sure if this "homework" idea is going to work well though. We'll give it a try, and anyone who doesn't do it is getting detention! Get drawing those buildings in, then come along on Wednesday 16th!

The buildings definitely look better when you have them all in, but we also need to:

- reduce their prominence (they crowd out other features with that dark colour)

- distinguish between different types of buildings, mainly so you can distinguish important buildings from your average apartment block or office

How about setting landuse for all of London? :)

If you are having trouble mapping stuff in London there is always the rest of the world you could help out with :)

@Tom Chance - Yeah building colour does feel a bit overpowering. Mainly when zoomed in like this. The roads are dawn over the top of buildings which has the effect of hiding the colour a lot when zoomed out.

@TimSC - I quite like the idea of getting the retail strips in as pink landuse=retail areas. Been doing a bit of that. In central London in gets a bit fiddly trying to decide when an area is no longer retail. Plus what landuse is an area like soho full of restaurants & bars?

@Nah. The rest of the world will just have to organise their own mapping parties :-)

If the last class is in the pub, is that where detention takes place?
