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

Sunday, 24 December, 2017

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

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

Thursday, 9 November, 2017

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

Friday, 13 October, 2017

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!

Roger Tomlinson’s PhD Thesis

Thursday, 12 October, 2017

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.
