I've got http://openpistemap.org in a vaguely working state, but it still needs a *lot* of work. At the moment it is only rendering data in the Verbier - Zermatt region and won't automatically render new data.

I've had a go at setting up a contour map on it as well, but so far haven't had much success... generate_tiles.py chucks up lots of "proj_init_error:failed to initialize projection with:+proj=latlong" after working through most of
osm.wiki/index.php/Contours_on_the_Cycle_Map, so that's something to continue fiddling with tomorrow.

So anyway, I've got Mapnik working and I'm starting to play with setting up contour data (and wow, that needs serious amounts of disk space!)

One thing that's bugging me though, is how to get OpenLayers to use degrees for the permalink? OSM itself seems to do it, but my code (and the OSM cycle map) don't... I tried swiping the "new OpenLayers.Map()" usage from OSM but it's still not happening...

More detailing of the land North of Headington way this lunchtime, after filling in the maze of pedestrian access around The Croft over the middle of this week (difficult, but rewarding: high walls, trees, and sunken footpaths make my n810's GPS unhappy, so multiple passes are sometimes necessary). I now want to capture the modern extent of the ancient Cuckoo Lane running down to Marston Lane and the new Centre for Islamic Studies . As ever, headington.org.uk has history, photos and out of copyright (-looking) maps:

Got my Nokia N800 the day before yesterday (March 4th). It is AWESOME !

Of course the 3 first things that I did with it: Updated the firmware for OS2008 (much nicer than OS2007), downloaded Maemo Mapper and downloaded all the maps of Sao Paulo (my hometown) into it.

New thoughts: I might release my java applet in the open, since now I want to mess with Maemo Mapper... It only downloads the bitmaps, it would be realy helpfull if it got the vector map from OSM and provided on the fly routing (couldn't manage to get routing working in Sao Paulo, only if I manually create the route points, but where's the fun in THAT !).

Cheers,
Diogo

I think Japan nearly has a complete error free coastline... the coastline error checker is only doing very sporadic updates though, so it's hard to be sure.

Spent some time this morning doing some improvement on the coastline in HK using the higher res Yahoo imagery available there. Some of what was there was very roughly traced.

Finished off an area north of the Bank of England today and yesterday. Very confusing warren of mainly pedestrian alleyways, many of which tunnel their way through large buildings and all of which are at the bottome of deep urban canyons so the GPS is useless. Mostly I've had to locate them on the map by relation to other ways and with some help from the Yahoo ariel pictures, so they should be topologically correct but may not be in exactly the right place if surveyed.

Added a few more road names near home at the weekend and also paid a visit to Amersham so was able to add in a couple more roads and paths over there. The map is pretty sparse in that area.

I've been trying to set up Mapnik, but I've hit a problem...

Trying to import the coastlines with shp2pgsql gives me errors:

INSERT INTO "shoreline_a" ("error","tile_x","tile_y",way) VALUES ('0','17','286','SRID=900913;0106000000010000000103000000010000000200000000000060307C71C1522159370A6F604100000060307C71C1522159370A6F6041');
ERROR: geometry requires more points

Followed by lots of:

ERROR: current transaction is aborted, commands ignored until end of transaction block

This is running under CentOS 5.1 with postgis-1.3.2-1.el5.rf - can't see any useful references to this error in Google though. :(
