OSMonth: Day 10

It begins… (and I’m having a hard time reconciling a bunch of payments so I don’t know who to thank right now)

  • fixed the planet script, an old copy generated the broken planet last night – new one tomorrow
  • updated schema to reflect yesterdays db changes
  • applet hacking

I’ve had to do a bunch of stuff for tonights ALN2 so calling it a half day.

OSMonth: Day 9

Thanks go to… Alex Willmer and Rhys Powell.

  • Doing database utf conversion so downtime needed. Done! tomorrows planet dump should speak utf8
  • Bunch of fixes to the Yahoo-based applet and deployed.

That’s it, two long jobs.

OSM Maplexed

Jerome Parkin at Lovell Johns has been playing with mapinfo, maplex and OSM data to produce pretty maps and get them in to Illustrator. This open mapping stuff could really take off.

The process involved the following

  • Downloading data from OSM
  • Load in file into postgis
  • Export to shape file format
  • Re-project the data from geographic to British National Grid
  • Re-coded (in arcmap) to match LovellJohns MapVU range
  • Maplexed (text placement) this re-coded data
  • Exported to Illustrator

As Jerome says ‘[It] looks promising as an alternative to expensive OS data.’:

OSMonth: Day 8.5

Begin again… thanks Frankie Roberto and Eckhart Wörner

  • Read through a bunch of latin1 -> utf8 stuff and announced downtime on monay to fix it
  • Wrote a GeoRSS ruby class for OSM (changeset 1771) and in the process found a big bug in the rss that OSM currently spits out that I WONTFIX
  • Got pagination (though not the rails native pagination, it’s slow) working with GPX files
  • put together a post about maplexing OSM data (see next post)
  • Hooked up the RSS feed and cleaned up trace pages so they are almost identical to the existing pages (changeset 1771)
  • initial go at viewing traces by user or tag

c’est fini

OSM in WorldWind

worldwind ‘lets you zoom from satellite altitude into any place on Earth. Leveraging Landsat satellite imagery and Shuttle Radar Topography Mission data, World Wind lets you experience Earth terrain in visually rich 3D, just as if you were really there.’

Think Google Earth, but before Google Earth came out (I think, correct me if I’m wrong). Anyway in their continuing efforts to make geographic information in the world more readily accessible, MetaCarta labs principally through Chris Schmidt have made available a WMS-C server of OSM maps, and now WW support! Check out the screenshot:

OSMonth: Day 8

Today is brought to you by the number 8, the day Thursday, and ISO 8601 which tells us Thursday is defined as day 4 within a week (the wonders of wikipedia). Oh and Frankie Roberto and Eckhart Wörner

  • Spent time trying to figure out why API spits UTF8 but planet dump doesnt, still. Think the simplest solution is going to be converting all the db data to UTF8 but need to run some tests to see if it’s going to do the Right Thing.
  • Looked at getting the Yahoo logo in the applet. This arose from our early screenshots, apparently it needs the Yahoo branding which is fair enough

I got called away mid day to deal with some boring stuff, so it’s only a half day. Tomorrow will begin at 8.5, supported by the same guys.

Winter Meetup

Following the 2nd anniversary party in London, move up north a bit to make it easier for other people to get to.

  • Birmingham, Prince of Wales pub, 84, Cambridge St, Birmingham, B1 2NP. Lat/Lon: 52.47975, -1.91305
  • Saturday 16th December from 1pm

OSMonth: Day 7

Today is sponsored by Trevor Spiteri and Dominic Hargreaves! Thanks!

Stuff done today

  • Got the camera back up
  • Going to fix some crazyness that stops the applet deleting segments. Arghhh.
  • Russ Philips won the poster and book that were offered as prizes, they’ll be on the way shortly. The method for choosing the winner was `select rand();` and `select count(*) from osmonth;` and multiplying the two numbers together to get a row number, then getting the row details.
  • Speaking of posters, the last one is up for sale on ebay
  • winter UK meet up confirmed (see next post)
  • Wouldn’t usually mention this here, but there will be a number of OSMers at Ask Later Nights #2 so it might be worth a look.
  • added tags to gpx files in the rails port
  • cleaned up the single gpx view, fixed import bug
  • replied to a metric ton of OSM email


OSMonth: Day 6

It begins… …and it ends. Been a busy day. Today was brought to you by Dean Earley and Russ Phillips. Have been hacking on the applet for the Yahoo imagery stuff and rendering lots of tiles with todays planet dump. Unfortunately the tiles didn’t really pay off and the applet won’t be live for a little while yet. Oh well.
