I have got some comments on the article on 41Latitude about
OSM.[http://www.41latitude.com/post/1310985699/openstreetmap-critique] My
comments concentrate on the criticisms as they relate to the map database in
Britain.
> USER INTERFACE
Not a database issue.
> APPEARANCE
Not a database issue although the default rendering seems to be easier on
British eyes.
> COUNTRY LABELS
> Country & City Labels Look Too Similar
Not a database issue.
> Country & City Labels Overlap
Not a database issue.
> Many State/Province Names Should be Simplified
Some parishes have been named in the form Welton CP. There may be other
cases.
> BORDERS/BOUNDARIES
> Country & State/Province Borders Are Too Similar In Appearance
Not a database issue.
> LabelsBut No Borders
I am unaware of this being a problem in the UK.
> HIGHWAYS/STREETS/ROADS
> A Rainbow of Roads
Not a database issue; possibly British users are more used to the default
rendering scheme.
> Some Roads Are Too Wide & Obscure Other Roads
While overuse of highway=primary/highway=secondary is certainly not a
peculiarly
American vice I cannot think of anywhere in Britain where anything above
highway=unclassified is so used.
> Uneven Road Coverage
> Some Counties Are Shown to Have More Roads Than Other Counties
Not a serious problem in the UK except where roads are genuinely unmapped
(because of the TIGER import US roads are more often badly mapped than
unmapped).
> Some of OSMs Roads Look Like State Borders
Roads in the UK do not (apart from a few at the Irish border) jump in
classification on borders therefore we do not get this effect.
> Comparison with Google Maps
Not a database issue.
> HIGHWAY/ROAD LABELS
> Hyphens
Not a problem in the UK. No prefix letter used in the UK can be misread as
a number.
> Inconsistent State Prefixes
Not a problem in the UK.
> Same RoadDifferent Colored Markers
This is not wholly a database issue though you get something similar when A
roads change from green to red.
> No Prefix
Not a problem in the UK.
> Semi-Colons
This can happen in the UK as it is a problem with editors.
> Colons
> Parentheses
> Semicolons & Parentheses
None of these are problems in the UK.
> Acronym Markers
Funny text in the ref field is rare in the UK though I once found an
underbridge
with a numeric ref tag.
> Some Interstates Show ExitsOthers Dont
Junction numbering is worth watching.
> CITY LABELS
> Uneven City Label Densities
Like road densities this (at a more detailed level than place=city) can be a
sign of variations in the level of mapping.
> Labels That Dont Appear Above Their Cities
This has occasionally happened; it risks the next problem.
> Multiple Labels for the Same City
This has occasionally happened, for instance Ilford. Names have also
sometimes
been deleted entirely.
> Misc. City Label Peculiarities
Not a problem in the UK.
> Hide-and-Seek Cities
This would seem to be a rendering issue that is triggered by having too
flat a
structure of places (see below).
> Major Cities Dont Stand Out Enough
What is a problem in the UK is that sometimes ceremonial status (St Davids
but
not Reading) has been used to the detriment of the quality of the map.
As an aside: is it practical to tag towns with populations as some US mapers
have suggested?
> Are Rogue OSM Users Promoting Their Hometowns?
Always something to watch. Why exactly is the town of Elgin tagged as
place=city?
