[OSM-talk] South West London

[Steve Chilton]

Very nice. 
I also download areas in chunks (OSM>JOSM>Osmarender) to check
progress/tagging, etc. Does anyone have a neat way of butting up
download sections to overcome the zoom=12 limit of JOSM? Currently I am
changing the values of the centre point of the OSM display before
sequentially copying each URL into JOSM. This is very fiddly and not
helped by the OSM map not changing the URL if you pan the map (could I
put that as a wishlist item?), and produces quite heavy data redundancy.
Does zoom=12 represent a specific range of x and y values, or is it
affected by where you are on globe (ie projection)? Analysing the
max/min box seems to give values of approx 0.044 and 0.088 for the range
of x and y. However putting these in to the max/min boxes (ie adding
0.044 to min for x) produces a 400 error [and the values seem to revert
to more accurate - ie more digits - ones based on zoom=12 (centred on
the calculated centre value?)].
Any comments/advice gratefully received.
NB: I want to add a revised North London png to the wiki but noted the
same upload error (which I believe is now resolved).
Cheers
STEVE

	As a result of Steve's work over the weekend (thanks Steve),
this morning I was about to download (in chunks) the whole of South West
London.  Roughly the area from Waterloo out to the M25.
	
	Here's what it looks like in when rendered with Osmarender2:

	Enjoy.

	PS I would have uploaded it to the wiki but I got this:  "The
file you uploaded seems to be empty. This might be due to a typo in the
file name. Please check whether you really want to upload this file."
