Sure, no problem.

Ah, right, is it fine if I use the z17 tiles as part of a Sutton-based slippymap I’m working on? (I believe you’ve already spoken to the other Tom about the actual rendering of it )

further to MTB comments; i’ve now added “mtb=yes” to the MTB track i’ve done, to see if that gets it showing up next week.

another request for the rendering: any chance of getting aerialways with bike=yes to show up?

NCR7 is getting there – slowly. thanks to whoever did the kilwinning to johnstone section – i’ve filled in some other blanks in ayrshire.

Frank – doing the contour numbers better is on my todo list.

Thomas – the 17th layer is only there for a different project. It only covers Central London and I’ve no intention of extending it anywhere else (it’s far too disk-wasting) so I didn’t want to show it on my site at all.

Gerco-Kees – the problem is that the contours are mainly interpolation between widely-spaced spot heights, and are therefore somewhat fictional. The more accurate I pretend they are (e.g. 1m contours) the more they are likely to be wrong or misleading!

Hi Andy, thanx for your explantation. I was just thinking, is it possible to adjust the interval of contourlines to, lets say, 1 meter for areas where the difference in heigt over the distance ratio (lets say: 1 m over 100 m = 0,01 but this needs tweaking i guess) is a small number… That would make the countourlines in our flat country (The Netherlands) a bit more intresting… Just my thoughts…

Toronto is rendered. Finally!

I’ve just been looking at the OpenLayers code you use, and notice that you don’t utilise the 17th zoom level. (numZoomLevels should be set to 18)
Just thought I should inform you, in case you weren’t already aware.

Great work! But with an awkward error: The numbers at the contour lines should be readable from low to high (readable from the bottom of valleys). This allows to identify the direction of gradients if you do not have rivers or peaks on the current map clipping.

Hi Gerco-Kees – that’ll be the coastline shapefile being out of shape. I grab them from http://tile.openstreetmap.nl/coastlines.html whenever I notice a bug like this – but sometimes I have to wait a couple of days if the world has gone blue again! Since Jon is doing the same for mapnik (grabbing them every now and then when they look good) we’re always out-of-sync.

I’ll grab some new ones this week. Thanks for pointing it out!
