Swiping in QGIS
I quite often find myself compare two images or a vector layer overlying a raster layer and, for me, a swiping tool is tremendously helpful in doing this....

Historic London Underground
I was at the London Transport Museum in Covent Garden recently and saw a nice animation of the historical development of the network. With all the underground mania in mapping, I liked this because it's one you see much less often and provides a nice historical perspective on the growth (and decline) on parts of the network. I couldn't find the animation that TfL used, but did come across the site of graphic designer Doug Rose who has produced a similar animation. So click here to view the map itself which (unfortunately!) uses Flash video. Quite fascinating.

OS Blog Redux
And a nice follow-up to last week showing the recreation of a favourite map using modern data by Charley Glynn. Charley has selected a 1967 quarter inch map of Scotland which is fairly small scale and quite good as a road map. The colour ramp for elevation is beautiful with the font and label placement elegant. Read the workflow - always interesting to see how people work!

A nice primer on R Project for Maps which provides a good introduction on the use of R for a range of GI applications, be they webmapping or raster analyses. The list of libraries and discussion of Microsoft R Open is particularly good. Worth a delve into.

QGIS at the Financial Times
A really interesting interview with Steve Bernard, Interactive Design Editor at the Financial Times. There are some great examples of work he has produced for the FT which principally involves QGIS and Adobe Illustrator. He is hugely enthusing of QGIS, so much so that he has a YouTube Channel dedicated to demonstrating the methods/effects he uses. Check it out as at over 30 videos now its a veritable resource.

Esri: 6 Easy Ways to Improve Your Maps
Some really helpful cartography tips from staff writer Lisa Berry on 6 Easy Ways to Improve Your Maps. I particularly like point 2, Find Signal within the Noise, which is pertinent to any kind of exposition. What is your main point and highlight it.... demonstrate you signal.

Maps.Me Adds OpenStreetMap
Great news from Maps.Me developers. The slightly more minor news is that theyve gone much more granular for map data downloads - so now you don't have to downloads 800Mb of data for the UK, but pick your regions. Much better.
The big news though is the ability to feedback map updates to the OpenStreetMap community directly through the app. Now that really is a brilliant way to improve PoI information. You can both add new points and edit point information.
Not only is Maps.me a great offline map app but you can now give back to the community.

OK, so it's another hackneyed take on the well worn tube map meme, but the Londonist's Lost London is a wonderful trawl down memory lane with the map providing location for those not so familiar with London. It's history, tourism and discovery all rolled into one and well worth spending 10 minutes looking at. Then go and visit some of the places!

Just a reminder that the AGI's GeoCom15 is coming up 23-25 November 2015 at the rather swish Chesford Grange Hotel just outside Kenilworth. Remember that its both the conference and exhibition, the latter of which is free to wander around, so no excuse not to register and come along to see myself and Prof Nigel Walford from the Centre for GIS speak.

Redux: think you know your countries?

EA DEMs Data Precision
UPDATE: An illuminating and quite hilarious read over here. The release of the LiDAR sourced EA DEMs is garnering some nice attention around the world although Martin spotted that the elevation values are recorded to a precision of attometers. Yes that's 15 to 17 digits after the decimal point!! As Martin points out, this is a huge waste of bandwidth and, I imagine, a default export setting. As I noted yesterday, the interface is functional, if a little clunky, and could do with some improvement.

EA DEMs of UK
As I noted earlier, the EA has now made its 50cm DEM data of the UK available at Data.gov.uk. You can find both the DSM and DTM 50cm products.... From either page you'll eventually get to this download page which is a touch slow but works well enough where you can download fairly small OS tiles (shame they cant be bigger). Ill be playing with these over the next few weeks to see what they are like.
