Cheers for all those answers, I'll try out all the solutions later
tonight/tommorw.  1 problem I have, is how do i get to see these
directional arrows, that show wich way the way goes?  (I have the latest
JOSM.)

Yep indeed I will.... http://www.openstreetmap.org/traces

Went for a ride this evening and thourght I would do some laps.  Sadly
my best time was about 18 miniuts, and top speed was about 15mph.  Don't
worry though, i don't need to waste time with pitstops, so I'll be
lauging on race day.

To sucessfully render an area you need to have all the segments pointing
in the same direction and you need the segments to be in the correct
order in the way.

In JOSM there is a tool to flip the direction of ways.

To get all the segments in the correct order (using JOSM), select the
way, remove all the segments from the way except the one that you want
to be the first one.  Then re-add each of the segments to the way
following the direction of the arrows.

2)  (hard to make out from render)  A small peice of the trunk road west
of

>why its doing this.

Somehow, there were *three* ways defined for this piece of road.  Tho
had highway=Trunk and were not being rendered (capital T), and the other
had highway=trunk, but had a couple of gaps in it.  I've seen this
happen a couple of times, but don't know what causes it.  Anyway I have
managed to delete the Trunk ones and repair the gaps.

3) My dismantled railway seems not to be visable (railway=abandoned)

There is no rule for this yet.  An opportunity for you to make one and
contribute it to the project.

4) How can I make a secondary road residential? Or an A road for that
>matter..(e.g. whittlebury)

Add this tag: abutters=residential to any road.

5) My rivers sit behind the woods in places, I need to make them visible

The order of rules needs to be fine tuned a bit.  Obviously rivers
should be rendered after woods and fields....  This will be in the next
version of the rules file (hopefully published in a day or two).

In retrospect, green lines for bridleways is not a good choice since
most of them run through woodland :-)  Actually, I think the colour
choice for woods is too dark and so there is not enough contrast.

Change line 1210 of osm-map-features.xml from
                        fill: #84b295;
to
                        fill: #b1efc8;

It should look better.

2) The look of paths and tracks from a distance looks the same.

Definitely agree with the need for waterway=stream, there is a huge
variance in the size of rivers.

5)Places that arnt highway=residential that are in the middle of towns
are

You can tag roads with abutters=retail, abutters=commercial, etc or you
can create areas and tag them with landuse=residential, landuse=retail,
landuse=commercial etc.  Personally I think creating landuse areas
produces a nicer result, but it is a but more work.  The abutters tag
for roads is quick and easy.

In a reply from andy (I think), it said that the current way in wich

Andy is working on a new scheme that will have a separation between
physical and administrative attributes.

Finally...I'm still so insainly confused as to why ways are being used.

It's great to see people getting nice results from OSM.  Looks like
you'll be getting to Silverstone racing circuit soon ;-)

Oh yeah...finally finally.... There is a page on the wiki where OS
faults

Someone said that the OS has admitted that they don't have the resources
anymore to be able to survey non-urban areas - so this doesn't suprise
me.

If you find any really blatant errors or anything amusing or anecdotal
then it might be worth adding them to the wiki page.  One of the
arguments that people might have for not using OSM data is that it may
not be accurate.
The Catalog of Errors page on the wiki is a place where we can show that
other maps have errors as well.

Right I'm Done...
