Some rough notes

  • lots of stuff in this trac query
  • parking areas are crappy
  • castle symbol doesn't exist
  • recycle symbol too
  • lots of green areas are rendered grey
    • leisure=common
    • leisure=garden
    • leisure=golf_course
    • leisure=pitch
    • landuse=allotments
    • landuse=cemetery (the crosses don't work properly, maybe plain grey/green aren't the best colour?)
    • landuse=forest (darker green?)
    • landuse=recreation_ground
    • landuse=village_green
    • natural=wood
  • none of the landuse areas are rendered differently, it might be useful to show retail / residential / commercial / industrial areas
  • streetmap.co.uk Reigate max zoom packs a lot in - what can we learn from them?
  • colour blindness - are walk/cycle/bridleways crappy for colour blind people?
  • streams currently appear as wide as rivers, making Hertfordshire look waterlogged.
  • railway=subway currently renders as a nondescript grey line.
  • water bodies in hyde park and regents park dont show up at high zoom
  • service roads could be better, they look kind of jarring IMHO
  • runways and taxiways should look nicer
  • white outline of areas, e.g. this water body: http://www.openstreetmap.org/index.html?lat=51.233623021933354&lon=-0.2118559592274252&zoom=16
  • waterway=riverbank produces two lines for the riverbank rather than a solid fill for the river

From trac

  • Footpaths: They show up as grey lines on higher zoom levels, when they shouldn't appear at all #293
  • Residential should be rendered like unclassified is (i.e. a thin line), until you zoom in, then both the same as a double line. Residential may be slightly different colour, possibly fill with light grey instead of white. #296
  • County Borders need to appear different to unclassified roads. Dashed lines would be more appropriate. #298
  • The railway=subway tag is not rendered as a railway. Instead it is just an ordinary white line. #353
  • railway="tram" is currently rendered as railway="rail". As a tram is most of time in the streets of a city, it could be rendered differently (perhaps a thin black line ?) #321
  • Names for leisure: sports_centre render under polygon #343
  • On further zoom levels (<17) in addition to the blue lines, cyclepaths also have a gray surrounding road which is unnecessary and makes them again seem more important than normal roads. #354
  • Could the coastline be rendered the same colour as rivers? At some zoom levels of 12 and lower is shown as a thin grey line: and then at higher zoom levels 13 & 14 as a white line, and at highest zoom levels as a white fill with grey outline #322
  • I believe there should be a distinction in the rendering of highway=unclassified vs highway=unsurfaced at higher zooms. See #380
