My new wishlist

Posted by Amaroussi on 15 February 2014 in English (English)

A lot of OSM-related things are in my head, so I should put them here in case anyone wants to help:

  1. Roll out route_master relations to London bus routes (Routes 21, 30 and 277 are starter conversions, for instructions see
  2. If the Central London Cycling Grid (CLG) gets introduced, then it's bye bye to the LCN for the area where the CLG will run... once the signs are up (source:
  3. Is the UK eligible for Humanitarian OSM Team attention given the recent events?
  4. Make my local area the densest in the world.

.3 - I doubt it. There are many pre-existing maps covering the UK and a large contingent of mappers already on the ground there. HOT's work is primarily where there is no good geo data to begin with

I'm open to correction on all of the above though :)

I posted a question on using the environment agency river levels web site sometime ago. By adding the elevations of car parks and riverside paths and for passable roads they could be assessed by monitoring the level from the Environment Agency . It may only work in flatter areas. see

There have recently been several threads on the Talk-GB mailing list about whether to map the effects of the floods in England, and if so, how. Most people seem to agree with not mapping them, at least not using 'normal' tags. Though a few people have mapped floods as natural=water, and closed roads as access=no etc.

Worth considering is how permanent the effects of flooding will be. ie if you map a road as closed now, will you resurvey it and update OSM if it reopens next week? And some OSM maps only update infrequently, so any changes to the data might be around for a lot longer.

Also, this doesn't really need the Humanitarian OSM Team, because there are already plenty of active mappers in most parts of the UK.

The Environment Agency already have extremely detailed maps for flood risks, see for example:

I don't think we need HOT, for the reasons given above, but I do think we have missed a trick in being able to provide maps with temporary features such as flooded roads/fields, which as well as being interesting could also be very useful to people affected by the floods.
