Hi folks,

I've done a trial run of building lowzoom (levels 8 to 11) tiles for Ireland and, consequently, the Isle of Man. It seems to have worked fine except for the coastline at the very North, near Derry, and the South, between Cork and Waterford. Has anyone else had a problem like this? It seems to mainly occur at zoom level 8, and only to a very small degree at higher zoom levels:

I made some progress on NCN 20 yesterday in Crawley, but it seems that the signage is not yet complete. The section through Tilgate golf course is fully signed, and I but once the edge of the residential area is reached, the signs dissapear. Nevertheless, I mapped the cycle path that I believe NCN 20 will run along up to Three Bridges Road.

Does anyone know about the status of NCN 20, regarding how complete it is?

I've just finished adding the MAX light rail Yellow Line in Portland.

I've decided that streets being mis-positioned are not the biggest problem with Tiger data. Rather, layers and intersections are. Now that I have read the Tiger documentation, I see that it does clearly state that there is no discrimination among overlapping layers (overpasses, underpasses) and that intersection points are put where the various paths cross. It is what it is.

Portland has several freeway interchanges with bridges, multiple layers of overpasses, train tracks, light rail tracks, and surface streets below. Unraveling the layers can be daunting. I started out being cautious, trying to preserve as many of the original nodes and ways as I could. Now I'm finding that it is quicker to go in and delete all of the intersecting nodes and ways in the middle and just lay down new ones as needed.

Of course, I still don't have anything to complain about. It does still mean that 99% of the mapping is already done, compared to the countries where folks are starting from zero.

Well, I compiled the UK data into CartoType format and this was the result:

06/04/2008 00:06 26,632,558 uk-080123.ctm1
26/01/2008 18:45 696,113,272 uk-080123.osm

That is, the CartoType CTM1 file is under 27MB for the whole of Britain. It seems to work fine using the Windows viewer. Tomorrow if I have time I'll load it on to the Windows Mobile viewer and see if it works acceptably fast.

In preparation for Long Bike Ride starting a week on Sunday, I did a hilly fifty-something mile stint on the NCN today - from Chepstow to Abergavenny on route 42, then on to Hereford on route 46.

Great fun even though I was utterly, utterly exhausted by the end of it and my legs still haven't recovered. Granny gear was engaged as early as the climb out of Chepstow, and Route 46 in particular is one for the "hills mean picturesque!" brigade (as opposed to "hills mean pain!"). I especially liked the extremely narrow road around Skirrid Fawr (it didn't quite get to the top, but felt like it) where, at one point, I had to 'reverse' to let an agricultural truck past - the road was that narrow. Of course, it helped that I was then rewarded with a lovely smile and a twinkly wave from the young female blonde ruddy-cheeked Welsh hill farmer who was driving said truck.

I was, however, a little miffed to find that all my effort to get to Hereford station for 5.50 (I think I made 5.48) was rewarded by a crap uncomfortable train with no buffet that was scheduled to wait at Shrub Hill for 15 minutes and Moreton-in-Marsh for 25. I mean, it could at least stop somewhere where there are shops. Or a takeaway.

I've had a long session today of improving CartoType's conversion of OSM data to its own format (CTM1 = CartoType Map format type 1) and writing a new style sheet to display OSM data more as it should look, and after quite a struggle I've met with some success. To recap, CartoType is a map rendering library that runs on mobile OSs like Symbian and Windows Mobile as well as on Windows (and Linux, Mac, etc.) It is not open source, but I shall make CartoType map viewer programs freely available, as well as the data conversion tool, style sheets, etc., so that people can look at the whole of the UK on their mobile phone without having to go online. The OSM data for the UK should fit into about 35MB in CTM1 form, so that's quite manageable.

Einen Monat wohne ich jetzt schon hier und heute war ich auf der Suche nach guten Inlinerstrecken in der Region. Von Böblingen bis Dettenpfronn war eigentlich auch immer eine Asphaltierte Strecke neben der Straße. Wenn jetzt noch das Wetter passend wäre.... naja

In Sulz am Eck ist mir dann der erste richtig gravierende Fehler in der OSM aufgefallen. Dank der GPS Daten müsste der aber demnächst gefixt sein ;)

Stage 1 of the new subdivision, Linden Grove, that I pass each day on my way to work finally got the street signage up this week. I biked around the streets with my GPS and logged them all and entered them into the map this afternoon. OSM is probably the first public map of these streets as the promotional information for the subdivision doesn't have the street names.
