A small problem of generalisation and a bigger problem of topology
I was recently teaching a class on introductory cartography where we were using a range of different socio-economic datasets including 2011 counties and middle super output areas (MSOA) of the UK from the UK Data Service....

Keep it simple...
Sage advice from John Lilly:
My big lesson was the importance of a simple message, and saying it the same way over and over. If youíre going to change it, change it in a big way, and make sure everyone knows itís a change. Otherwise keep it static.
...and that goes for any type of communication. Keep the core message simple to understand because whilst the implications may be profound, your target audience needs to be able to take it in and interpret it unequivocally.

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. I cant vouch for the courses themselves, but it's great to see such variety springing up. QGIS is my goto for geoprocessing on a daily basis...

Note to self... duplicating a tab in Firefox
This is one of those actions that is incredibly useful every so often... you have a tab open and you actually want to duplicate (so you have an active copy) and then carry on working with the current tab. Except there is no "duplicate tab" (or clone) option when you right click in the window or on the tab. This is actually one of those Unix-esque type daisy-chaining of functions to achieve the same in result. So... middle clicking on a link will load that link in a new tab (very useful itself). Solution:
middle click on the reload page icon (next to the address bar)
Always easy when you know how!

It's a , stupid!!
Yes, one of the manuscript writing moments where I was using Endnote and wanted to cite a webpage for an organisation. Enter the oranisation name in and the European Geosciences Union gets turned into...
This is one of those annoying diversions where you either go and work and the syntax for citing it or... do it manually.
In this instance I Googled it and found that all that was needed was the humble
at the end of the author field. It's always easy when you know how!

FREE EPRINT: Selecting cameras for UAV surveys, GIM International
James O'Connor and Mike J. Smith (2016)
With the boom in the use of consumer-grade cameras on unmanned aerial vehicles (UAVs) for surveying and photogrammetric applications, this article seeks to review a range of different cameras and their critical attributes. Firstly, it establishes the most important considerations when selecting a camera for surveying. Secondly, the authors make a number of recommendations at various price points.

Got an old ISO disc image....
.... as I have. I was interested in accessing the contents of an old ISO disc image from an age old data CD. There are a number of tools to look inside these, but at times you just want to emulate a CD/DVD drive and run it directly. There are a range of tools to do this but I wondered if there was an easy option... and there is! Under Windows 10 you can now directly "Mount" the ISO image and it will appear as a new CD-ROM on your PC. Just right-click and "Mount." For older systems Microsoft do a device driver bundled as the Microsoft Virtual CDRom Control Panel (which I first came across here).
Voila! Problem solved.

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.

Studio of Objects at RGS
The Studio of Objects (see all my previous posts on the project), which recorded the interior space of Paolozzi's studio at the Scottish National Gallery, was available for viewing and interaction at the Royal Geographical Society Annual Conference last week in London.
I took part in a panel discussion on the arts and sciences (see my personal page for slides and mp3) and then for the rest of the day the latest beta version was available in the main hall. In fact, the installation was so popular that it made a return visit on Friday where delegates had a second bite at the interactive cherry!

How big is your image? O, 53 billion pixels!
DPReview have a review of Bentley's rather impressive 53 billion pixel of one of their cars on the Golden Gate Bridge. It might not be obvious at first glance but it is there!! Made up of over 700 photos taken at varying focal lengths (between 300 and 1500mm... bet that puppy cost a few pennies!) using a motorised panoramic tripod head it is one monster of an image that require a fare bit of TLC is post production - most notably the bridge can move ~8m in either direction in high winds! Head on over to Bentley to take a peek.
