Redux: think you know your countries?
As a follow on to last weeks Think you know your countries? blog, have a visit to TheTrueSize.com where you can select countries and move them around a mercator map at will to compare them to any other country. How big is Germany, really, compared to Angola??

Think you know your countries??
Then try your luck with the Mercator Jigsaw - took me about 5 minutes with some distinctly tough ones in there. And - goddamn - that Mercator projection can be problematical ;)

Mapping the Syrian Conflict
An interesting short piece over at the BBC about mapping the Syrian conflict - what is interesting is the BBCs lack of understanding about how data, (online) mapping and journalism are merging together to create a new generation of (often (remote) citizen) data journalists....

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.

Its a bit twee in its connotations, but "big data" keeps popping up all over the place. My brother sent me the link to this story: "5 Ways Big Geospatial Data Is Driving Analytics In the Real World". There is nothing overly new or exciting in the actual research itself, however what is interesting is how "geo" is now overtly mainstream. A lot of the benefits and issues associated with geodata are now more widely understood and appreciated meaning that more people want to use it. Definitely boom times...

Liam Neeson Kill Map
Clearly Liam is one badass guy!!!! Love the kill map just for the way it presents information that you find yourself asking for during a movie. In my case (re)watching "Taken" and thinking, whats the body count in this?? Star Wars 1 surprised me though.... I wonder who holds the cinematic record?! Anyway, its nicely designed and more as an infographic, but still feel it could be improved.

International Map Year 2015
Well the International Map Year has passed me by up until this point... that said it formally kicks off at the ICA in Rio de Janeiro in August 2015 and runs through until December 2016. As the website says: "International Map Year (IMY) is a worldwide celebration of maps and their unique role in our world. It's organized by the International Cartographic Assocation (ICA) and supported by the United Nations (UN)."
So things are just starting to get going - there's a helpful news item in the ICA newsletter. Interestingly no UK organising committee...yet!

Although a little dated (it was produced using v2.0 and we are currently on v.2.81) Lex berman's QGIS Workshop is a very easy to access and use intro and primer to QGIS, with a smattering of useful links. Worth looking through for hints and tips.

OS Open Data
OS recently provided a recent update on their OpenData products as a reminder of what is available and some of the new products. Indeed, take a look at their main OpenData page, the products page and the download page. There are some really good products here including Meridian (medium scale vector), Terrain 50 (medium scale DEM), CodePoint (postcodes), BoundaryLine (administrative boundaries) and a range of raster products. Very good for a range of mapping projects and all using the very flexible Open Government License. Enjoy!

Feels appropriate, given the eclipse across northern Europe (very nearly now!) to post about the topic..... and point people to the very good Eclipse Maps (Esri employee by day, eclipse fanatic by night). Below is an example from a couple of years ago - really nicely produced and very clear. Worldwide eclipses 2001-2020 are shown here.... the gallery has a good range of maps both historical and predicted.

QGIS 2.8 Wien
QGIS 2.8 Wien has just been released which sees a plethora of useful features added. The latest version introduces a long term release (LTR) which will provide a 1-year support cycle with backported bug fixes. This is particularly useful for businesses.
And, along with the latest version we now have a UK QGIS Shop for the purchase of all those less than useful items of clutter you might want to show off with!!
P.S. And as a reminder, remember that QGIS is completely USB portable friendly. Just copy the entire QGIS directory over to your USB stick and then double-click on bin\qgis.bat file.

Digimap offers file geodatabase
Digimap is now supporting the file geodatabase format for downloading Mastermap. Whilst GML is a good standard for data transfer, Digimap's users by an large use ArcGIS and QGIS and by offering it this way it should make life much easier for using Mastermap.
Note that the file geodatabase has long been touted as the successor to the shapefile, but Esri dragged it's heels over publishing the api although it now works on Windows, Linux and Mac (32/64bit) so hopefully this will help push things along a little more.

QGIS Under the Raedar
Really nice article from Alasdair - I can only echo his comments. QGIS has reached a nice level of maturity and usability and is now well worth the investment of time. I would add a couple of my own points to this:
1. Portability: just copy the QGIS folder on to your USB stick. It runs from there happily
2. Speed: for such a large application it is relatively fast.
I have been working on a project with colleagues at Wageningen (Saskia Keesstra and Niels Anders) involving some spatial processing using Python - this utilises shapefiles for data storage and QGIS is wonderfully rapid for loading, symbolising and querying data.

Crowd georeferencing at the British Library
A really nice georeferencing project over at the British Library that has been going on since 2011!! Scanned by Microsoft, the >3000 maps are available for the public to georeference so they can be overlaid with modern mapping. Thoroughly worthwhile project and a slick interface - watch the 57s video, log in, get going!

QGIS Chugiak Released
Just a brief note that QGIS Chugiak has been released. For those that haven't used QGIS recently it is highly capable and becoming increasingly user friendly. Well well well worth further exploration. Also worth noting that by default it is a portable app - simply copy the QGIS folder on to your USB stick and run it directly from there! How cool is that?!

Interesting article on interior mapping over at the NY Times.... the Finnish Company Indoor Atlas is using changes in the magnetic field of a building interior to location your position (to within ~2m). Interior is definitely the new frontier and paves the way for you to optimise your route through Tesco - traveling salesman all over again!

OS Carto Home!
The OS unleashed their cartography "home" this week titled Cartographic Design and Development - its well worth dropping in to and it shows some excellent resources, examples and advice on sourcing, resourcing and designing maps. I particularly liked the Cartographic Design Principles and the examples they show. Well worth a look for anyone who needs to design and make maps.
