OSM gets Isle of Man Government Data
Dan Karran writes that he has received an official, recent (2007) dataset from the Isle of Man government, comprising of a 1:25000 raster with tourist points of interest (POIs), and detailed satellite imagery from 2001, with a licence suitable for tracing into OpenStreetMap. This is great for OpenStreetMap and for the Isle of Man. Although […]

Open Plaques
The Open Plaques project, currently in alpha, is aiming to catalogue, photograph and georeference the numerous “blue plaques” scattered around London and elsewhere in the UK. Blue plaques generally mark the house where someone famous lived, or some other event happened. The London ones are generally blue and circular, and are put up by English […]

OpenStreetMap Road Coverage in England
Peter Reed has been doing some excellent work comparing the Department of Transport measured road lengths by English county, and comparing them with the total lengths of roads in OpenStreetMap. This has only recently become possible to do with spatial data purely in OpenStreetMap, because the English counties have now been completely added to the […]

Mapping Party and Mapzen Sneak Peek!
The next London mapping party is on Thursday evening, in Mayfair, the really posh bit of central London (you can tell its posh as it only has one bus route going through it.) See here for details and to signup. What’s special about this one is that Cloudmade’s in-development mapping editor, Mapzen, might be being […]

Map Cake
One of my favourite bits from the State of the Map conference last weekend was when they bought out the cakes: If you are familiar with London’s geographical layout, you might recognise the big green blob on the cake on the right as being Regent’s Park. I think my slice ended up being part of […]

State of the Map 2009 Review

I skipped the “business day” on Friday and joined the conference for the Saturday and Sunday, when it reverts to being a community conference. My favourite talks were: Andy Allan showing […]

State of the Map
I’m off to the State of the Map conference in Amsterdam on Friday. It will be interesting to compare with the OSGIS UK conference a couple of weeks ago. I almost certainly won’t be live-blogging the event, thanks to data-roaming charges, but if I get around to setting it up, there might be a few […]

Map of UK Scenicness… and Pubs
Here’s a little something I knocked up, based on the MySociety scenic score data release last week, as well as OpenStreetMap’s data for the UK – including particularly its pubs. Basically, the vote point data was converted to a surface, using an IDW (Inverse-Distance Weighted) function. The cell size was pretty small (1km), so there […]

Spherical Mercator Maps in OpenLayers 2.8
Following on from my previous post, it is indeed much easier to put Spherical Mercator “Google-style” maps into OpenLayers, following the 2.8 release this week. Spherical Mercator is a pseudo-spatial reference system (SRS) that takes some liberties with strict geographic accuracy, to provide a projection that requires the minimum of maths to compute – as […]
