I've waxed lyrical about the Ricoh GR being a great UAV camera before - well the long awaited successor has been announced (but hasn't yet landed) and summarised over at DPReview. The interesting aspects of the uprated specs are IIS (inbody image stabilisation), 24MP sensor and touchscreen. The resolution boost and IIS will be of significant interest to UAV users so it will be interesting to see how it performs out in the field.

TED: Academic research is publicly funded ó why isn't it publicly available?
An interesting talk from TEDxMileHighWomen. Worth a watch to get a short 10-min summary of some of the issues involved with publishing academic research - the comments are worth a look too....

Open Access UK Unit Postcodes
The Ordnance Survey released their Code-Point Open product a few years ago that has the OSGB centroids of the unit postcodes. It's very useful but is only points - if you want the postcodes areas as polygons then you need to license Code-Point with Polygons (snappily titled!). A number of people have derived unit postcode areas using Voronoi polygons including more recently Mike Spencer with some intro at his Scottish Snow site.
It's worth noting that Voronoi diagrams equally partition space between points and nothing more - they are not equivalent to unit postcodes (which can be arbitrary) but are a reasonable first guess. One dataset worth having for your arsenal of spatial data!

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!

Pursuit by Mike Oblinkski
The only words to describe this are awe inspiring, spectacular, mesmerising - this is a visual tour de force that is matched by wonderful evocative music. Just the basic stats behind it say it all... completed over three months, 27 days of filming, traveling across 10 states, with 28,000 miles of driving and over 90,000 time-lapse frames. Produced to 4k this movie is simply begging to be viewed on a MASSIVE screen. Now if only my local cinema would show it as a short.
Utterly brilliant. Watch it.

Earth-i Launches Vivid-i
Earth-i has just launched a new SSTL built satellite which is claimed to be the first to provide full colour UHD video - UHD is 3840x2160 pixels (8MP), shooting at 50 fps (compared to Landsat 9's ~12,000x12,000). That's a lot of downstream data, although it would appear it's not the video they're interested in, but the multi-temporal data. Think super resolution to give them an effective ~70cm pixel size, but also stereo (and so 3D). This is the first of a planned 15 satellite constellation which could provide global coverage and much more agile mapping capabilities. Video is clearly the new high resolution!

FREE EPRINT: Summary of activities 2017, Journal of Maps
Mike J. Smith (2018)
Journal of Maps
As a journal we notionally have two overlapping sets of "customers" - readers and authors. Authors provide the content whilst readers consume it. In a subscription funding model, readers pay for journal production, whilst in an open access (OA) model, authors pay. Somewhat uniquely in publishing, advertising plays a very limited part. And akin to commercial publishing, we have an overall journal editor (or Editor-in-Chief) and section editors (or Associate Editors).

Time lapse to a beat
Utterly stunning timelapse from Julian Tryba of the New York skyline - just when you thought you had seen it all, this takes a giant leap into the future. This makes the landscape a pallette which you can draw upon and integrate into a piece of music. It is wonderful. Sit back, watch, marvel (and then go and read how he did it).

Zenmuse X7 DxOMark Tests
DPReview report report on DxOMark's tests of the Zenmuse X7 and it makes for some impressive reading... it's a quality sensor that has nearly 14 stops of dynamic range with good low-light performance. This line from the review pretty much sums things up:
it delivers results that compete closely with those from a high-scoring APS-C format DSLR, despite being housed in a camera thatís mounted in a stabilized gimbal and specifically designed for aerial photography.

Space in the news...
A couple of nice space links.... first a celebration of the Russian Soyuz system. An engineering marvel that is reliable and low cost - a feat for any product but the fact that this is over 50 years old and just keeps working is remarable.
Second, GIS-Geography have a list of 50 satellites in 30 words or less. Vital reading for any researcher... of undergraduate geographer!

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.

The first set of slides are below and the second set on this page.

PhD thesis: writing it up (and the art of procrastination)
I recently had an opinion piece published in Times Higher Education - this is advice on the process of writing up, how we all procrastinate on finishing it and what to do about it! It evolved out of discussions with PhD students over the years and advice to them, as well as fighting my own procrastination monkey at times. These things have worked for me and for some students, so if you struggle with getting those words down on paper... give them a try!

Straight from one of the best books I've read on communication (Trees, maps and theorems by Jean-Luc Doumont), is this paragraph on helping stem the flood of emails. Sage advice indeed:
If you are buried under too much incoming email, you may feel helpless about it. Yet, without hoping for a revolution, you can still take concrete steps toward easing the overload. To receive less email, simply send less email - and send better email, too.
So, starting today, think before you send and if it's not required, don't send it.

Is this the next Uber Drone, coming to some skies near you? As the article says, would like to see 1000 hours of safe flight time first and the ability to fly with only two motors by feathering then should there be a failure. Exciting times though - I get a sense of scenes from The Fifth Element coming true (that would be Ruby Rhod first maybe)!!

And the cost of hiring a UAV is being driven down.... Dronebase is your AirBnB of UAV operators. Don't pay over the top and go to one site to find them. The growth has been extremely rapid - see what their investors think. Its a great idea and, well, a very useful resource.

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.
