Central London is a area in London at latitude 51° 31′ 12″ North, longitude 0° 7′ 37″ West.
Central London is a pretty awesome example of many people collaborating on one area. There's areas of amazing detail. However central London is also an example of the difficulties of tracking completeness when so many people are involved. We reach a richer level of detail in areas which are more interesting to mappers, while other areas are neglected. A lot of fly-by mapping happens, and unlike in smaller cities or some areas of London suburbs, we don’t really see individual mappers taking ownership of an area.
Aspects of central London to work on:
- POIs - Hopefully our coverage of POIs such as pubs, banks, supermarkets, is pretty good. But smaller POIs which are also important can fall between the gaps. e.g. post_boxes, telephones, cash machines are hopefully treated as high priority by most mappers, but in the past they may have been missed, so now knowing where they’re missing is the challenge.
- shops - These days we’re pushing towards mapping every single shop. A big job! And never-ending of course, since shops change a bit.
- Buildings - Tracing over building outlines. Back in 2009 Harry blogged about this a lot:     ..and since then we have improved coverage, but there’s still patchiness, and important areas of London which haven’t been done yet.
- House numbering - For addressing. Following the Karlsruhe Schema
- Buses - We’re doing pretty well with routing relations (see Buses) As rendered here. However the NaPTAN import brought in some inaccurate bus stops data, and also we have lots of work to do merging bus stops.
- Landuse - Drawing polygons in crowded areas can be fiddly, and in general there’s plenty of unanswered questions about landuse polygons, but people have been getting on with it, sometimes using guesswork it seems (feel free to fix landuse if it seems wrong)
