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.

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!

Kickstarter Plug: Spooly
Wanted to give a plug to Spooly who are running a Kickstarter campaign at the moment. I've not link to them, but the product looks great - I'm always on the lookup for innovative products that solve problems or make life easier. And this is a little gem - its a USB charge cable but incredibly small and rolls up into a perfectly neat package. What can you say other than a fantastic piece of design, doesn't cost much and worthy of the plug.
