This paper outlines a collaborative project between a group of Fine Art and Geography students who helped develop and contribute to a conversation about recording ‘place’. Introducing methodologies from both disciplines, the project started from the premise of all environmental ‘recordings’ being ‘inputs’ and so questioned what could be defined as ‘data’ when encountering a location. Brunel’s Grand Entrance to the Thames Tunnel (London) provided the motivation for 10 objective and subjective ‘recordings’ which were subsequently distilled into a smaller subset and then used to produce a short film that was presented at an international conference. Important to the collaborative nature of the project were ongoing opportunities to share equipment, techniques, material and references across disciplines. It was an experiment to measure the potential for ‘mapping’ to capture physical and historical information, as well as embodied experience.

FREE EPRINT: Land inundation and cropping intensity influences on organic carbon in the agricultural soils of Bangladesh, Catena

M.J. Uddin, Peter S. Hooda, A.S.M. Mohiuddin, Mike J. Smith and Martyn Waller

Land inundation is a common occurrence in Bangladesh, mainly due to the presence of two major river systems -the Brahmaputra and the Ganges. Inundation influences land use and cropping intensity. However, there is little information on the influences of the extent of flooding and cropping intensity has on soil organic carbon (SOC),particularly at the landscape level. To investigate these influences, we collected 268 surface (0-30 cm) soil samples from 4 large sites within the two alluviums deposits (the Brahmaputra river and the Ganges river), on a regular grid (1600 m). The findings show that SOC levels are generally low, reflecting the intensity of agriculture and land management practices. SOC variability was higher across the medium high land (MHL) and medium low land (MLL) sites than in the high land (HL) and low land (LL) sites. The relatively low SOC levels and variability in the HL sites indicate soils here might have reached to equilibrium levels due to higher land use intensity. Topographically higher lands (HL and MHL), due to less of inundation, had higher cropping intensities and lower SOC’s than lower lands (MLL and LL), which had lower cropping intensities, as they remain inundated for longer periods of time. The findings clearly demonstrate the intrinsic influence of land inundation in driving cropping intensity, land management practices and SOC levels.

Creativity is one of those tropes that seems to do the rounds regularly in, well, creative circles. Almost by definition, it is levelled at the arts, in part because its base definition is along the lines of the ability to create. Withinthis context, cartography is well-poised because any map requires the cartographer to create a new, unrealised, graphic product.

challenge posed by a heavily time-constrained culture; specifically, tension exists between opportunities presented by working with business and non-optional duties (e.g. administration and teaching). Thus, to justify the time to work with business, such work must inspire curiosity and facilitate future novel science in order to mitigate its conflict with the overriding imperative for academics to publish. It must also provide evidence of real-world changes (i.e. impact), and ideally other reportable outcomes (e.g. official status as a business’ advisor), to feed back into the scientist’s performance appraisals. Indicatively, amid 20-50 key duties, typical full-time scientists may be able to free up to 0.5 day per week for work with business. Thus specific, pragmatic actions, including short-term and time-efficient steps, are proposed in a “user guide” to help initiate and nurture a long-term collaboration between an early- to mid-career environmental scientist and a practitioner in the insurance sector. These actions are mapped back to a tailored typology of impact and a newly created representative set of appraisal criteria to explain how they may be effective, mutually beneficial and overcome barriers. Throughout, the focus is on environmental science, with illustrative detail provided through the example of natural hazard risk modelling in the insurance sector. However, a new conceptual model of academics’ behaviour is developed, fusing perspectives from literature on academics’ motivations and performance assessment, which we propose is internationally applicable and transferable between sectors. Sector-specific details (e.g. list of relevant impacts and user guide) may serve as templates for how people may act differently to work more effectively together.


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 - 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.

As Erica Stone implies, she hasn’t got much experience in academic publishing and it unfortunately shows. There are some points well made, but there is and underlying naivety about the role of publishing, the cost, the requirements of universities and the amount of time academics have. As I noted in my editorial this year:

Academic publishing is a knowledge distribution and academic assessment system, partially funded by universities and research institutes.

To publish you have cross-subsidise, or go down an author or reader pays route - ironically (and perhaps to the chagrin of the OA camp), OA is currently costing the system more than a subscription model on an annual basis and probably on a pageview basis too. But, let’s keep the debate going!

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!

Waldo Tobler

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.

You’re Waiting For a bus… and a SenseFly Comes Along

I commented late last year about DJI becoming a camera manufacturer… this is an interesting and exciting move simply because the quality of imagery from drones has lagged significantly behind the rest of the camera industry. So whilst there are clearly regulatory challenges that need to be overcome through hardware and software engineering, the end-user is interested in the best visual imagery possible and drone manufacturers are starting to wake up to this fact.

So I was surprised to see that SeneseFly had announced back in 2016 its (then new) eBee Plus offered an hour of flight time within a ~1kg airframe that can incorporate RTK/PPK positioning (forget those ground control points!) and multi-spectral/thermal. But… they have also introduced their own homegrown air camera dubbed SODA (Sensor Optimised for Drone Applications). It is extremely light on specification however their website notes its a 20MP 1” fixed lens camera. This that likely utilises Sony’s standard 1” sensor, although it would be useful to clarify the exact size. Is it genuinely 13.2x8.8mm? Taking their GSD example figures, that breaks down to a 10mm focal length lens, equivalent 27mm on a full-frame camera. Interesting there is a single global electronic shutter which is a good thing for a fixed-wing aircraft: it should stop the problem of a rolling-shutter.

Fascinating to see the drone-camera market develop and it’d be great to see some results from this baby.

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!

QGIS3 Beta

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.

Video file sort order on my Pico projector

A (long) time back I wrote about the Acer C112 Pico Projector I was using. I’ve since upgraded to the Pico Genie P200 which gives a great 200 lumens of light and has microSD, USB and HDMI ports to allow all sorts of connectivity along with a built in battery. It’s not perfect - but its very good (and I still follow the same routine for transcoding with DVDDecryptor and TEncoder).

One minor irritant was that the sort order of the files on the memory stick appeared to be shown by date on the projector - I used Nico’s useful BulkFileChanger and… it made no difference. Obviously the embedded Linux system wasn’t using file dates. In fact on my (FAT32) USB stick it’s using the order of the files in the FAT - what was successful was using DriveSort. Problem solved - I suspect this affects a small number of embedded systems (mp3 players, projectors etc) that have had some lazy coding and don’t sort the files on portable drives.

How to be a journal editor

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 that’s 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!

DJI is a camera company

Two years ago I blogged about the introduction of a micro four thirds camera by DJI, followed last year by the Phantom 4 which allowed RAW capture. These are giant strides by a drone company trying to get better image capture - but the capabilities of the cameras still lagged significantly behind COTS (commercial off the shelf) systems.

One of the big drives for DJI has been the film industry and so there has been some buzz on the wires with the announcement of the Zenmuse X7, a camera built by DJI rather than using a partner’s system that has some interesting specs (see DP Review). This is primarily aimed at cinematographers, but as DP Review note this is actually a highly disruptive move by the company. It marks their entry into camera manufacture and introduces an APS-C sensor (24 MP), with a new lens mount and suite of lenses. So a larger sensor size but at a dramatically lower weight and smaller dimensions - the flange distance is a tiny 16.84mm with a minimum weight (including lens) of 630g.

So, let’s say it, this is a camera (and integrated into a system) that is destined for photogrammetry. Watch this space, disruption is coming!
