Andrew's GIS Platforms reloaded

A GIS group discussion prompted me to update this list of selected desktop & web platforms by delivery and cost - note that it excludes commercially serviced FOSS, as well as web & mobile apps - and the usual caveats apply, see details on last page.

CoDE Conference 2016: Creative Communication

Just attended a conference crossing over art and science at Anglia Ruskin University, Cambridge Culture of Digital Economies CoDE. It ranged from the impact of video games, through a master class in drone cinematography and video exhibit The Crossing, to interactive demos and lightning talks. Two items stood out for me: Sonic Pi freeware to help introduce school children to digital music, and Lichen Beacons a Raspberry Pi and beacon interactive display of imagery and poetry:

Fort McMurray (Canada) Wildfires Social Map

[20/05/2016 update: noticed the dearth of social feeds? People are busy fleeing the area!
Also come back often as, sadly, fires that receded last week were returning this week...
]

The wildfires around Fort Mc Murray in NE Alberta of W Canada were well covered in the press. Their origin is introduced in the splash screen below, which includes a broader context in the NASA brief. A modified pre-existing DIY Weathermap for Kuwait, especially the wind information, added info for Fort McMurray and MODIS data, whose hotspots are indicative of fires. Features inspired by Esri Disaster Response maps were finally styled with social feeds below. Twitter feeds for #YMM (airport code), #YMMfire and #YMMhelps were added to Flickr, Instagram and Youtube for the previous 5 days.

Another Take on Climate Change, Part VI

previously asked  how current vagaries of climate may relate to earth's magnetic field reversals? One problem was that geological records (ocean bottom magnetic stripes) didn't span well into historic records (volcanic lava deposits)! Well this appears to have been addressed in this video:

Animation of historic Paris building footprints

Bâti Paris is a beautiful suite of maps of the Parisian buildings and listed monuments since the 18th c. posted by Etienne Côme. I gave it an organic twist by rotating and mirroring each time slice, to make it look like a breathing lung, and posted it as a video:

Another Take on Climate Change, Part V

Parts I, II, III & IV from March 2011 became relevant in a comment yesterday on Euan Mearns post on extreme climate. He pointed to the Laschamp event, and suggests this: that the wandering of the North Pole heralds a impending magnetic reversal, such as happened 4000 years ago evidenced in the French Massif Central near Clermont Ferrand.

Global vector datasets on the web

I described exactly two years ago posting NOAA's global shoreline dataset on my AWS stack - added  recently to personal portfolio for easy access - I discussed here earlier, why post global vector datasets, when web services provided such varieties of backdrops? At issue is that vector data are so large at global scales, that NOAA above and Natural Earth post them as various scales, where details are trade-off against scale.

To teach or not to teach, that is the question

With apologies to The Bard, whilst the internet in general and YouTube in particular are great tools - I use them here and on YouTube myself - there is the danger of posting educational videos uncritically.
