I was sad to see that Waldo Tobler passed away last month - a lifetime geoscientist he contributed huge amounts to computational cartography but will be best remember for the First Law of Geography. Some more details at GeoLounge and in the original paper.
However I love the CSISS Classic which was a tongue-in-cheek experiment with Peter Gould on geocoding. Read it because its wonderfully powerful way of showing students about geocoding. Hopefully we'll see an anthology of his work in the not too distant future.

QGIS 3 features
QGIS 3 is well and truly out now - download your copy here. And the good folks over at GIS Geography have put together a list of QGIS features that are in the new version. Some of the highlights include 3D (1), coordinate reference bounds (5), geopackage (7), background processing (8), new print composer (13), refined graphical modeler (25), but they are all worth taking a look at as it might just be a solution to the problem you have!

QGIS 3.0 is well and truly on its way with lots of updates, modifications and new features. Here is a great 24 days of Christmas list. Don't forget to download the beta, play and report bugs back.

Roger Tomlinson's PhD Thesis
UCL's Department of Geography have digitised Roger Tomlinson's PhD thesis from 1974 and placed it online (see James Cheshire's blog post). As the grandfather of GIS it makes compulsive reading - although disappointing UCL haven't placed it on EThOS.

That would be DuckDuckGo Bangs by the way! A fantastic way to quickly redirect your search/query to another service - I use !w (wikipedia), !g (Google) and !yt youtube lots. Last year I requested one for my favourite mapping engine Streetmap and lo-and-behold they have release it.
Just search !smap

OSM then and now
Quite astonishing what 10 years of volunteered mapping can do.... wonderfully exposed at OSM Then and Now. Use the slider and be amazed!! Ive centred upon Bletchley, a suburb of Milton Keynes, and home to Bletchley Park and the home of the codebreakers.

GIS-Geography had a nice geosheets tutorial just before Christmas which is worth a look-in. Geosheets is not a service I had seen before and operates as a plugin for Google Sheets, adding functionality to geocode spreadsheet data and plot on a basemap. Of course ArcGIS Online and, indeed, Google MyMaps. However Geosheets offers you the ability to create within Google Sheets itself using some simple syntax. I wonder if they have enough to survive (don't complete with Google or Esri!) but, in the interim, it's another toolbox for geoenthusiasts.

Shapefile or geodatabase?
A nice overview and comparison of the shapefile, personal geodatabase and file geodatabase over at the guys at GIS Geography. Its a good succinct summary and review of the pros and cons. They do note that the file geodatabase is proprietary (to Esri), but not that the shapefile is too. And whilst (quitea while ago) Esri published a whitepaper detailing the specification of the shapefile its worth noting that they have released the API to the file geodatabase as well.

Get ahead in QGIS ...
I've already blogged about Steve Bernard's excellent YouTube Channel on QGIS, well to continue in that vein, here's a link to a series of free (and paid for) courses in QGIS over at GeoAcademy.

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!

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.

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!
