Listen to the scientists

[Update 2: in Part II, XR Cambridge Rebel Scientists produced a video tying it all together
Update: East Anglia Fenlands + London Thames Valley inundation models now on YouTube!]

This is what happened at the first Extinction Rebellion Cambridge working group of concerned  scientists, on the topic of sea level rise (SLR) among many others discussed then. As posted earlier here, the scientific consensus lies at 0.5 and 2 m. SLR by mid- and end-century in moderate emissions and far-tail scenarios, respectively. That meeting reiterated, however, the importance of an extreme scenario, ~ 6 m. SLR from the melting of various ice sheets: 7 m. is in fact the default SLR setting for the original sea level rise map, flood.firetree.net.

Climate Emergency maps as easy as 1-2-3

Almost 2½ years ago I blogged then presented Emergency response maps as easy as 1-2-3 - in fact that helped spur on my current venture described in previous posts - and now apply the same to do inundation maps from sea level rise as well as river run-off.

Areas affected by sea level rise scenarios

[ Update: There follows a tally here of what we've collected so far. ]

So far we've looked at sea level rise, timing, temperature regime and risk of flooding from land and from sea. These scenarios were developed using open data from Ordnance Survey and Climate Central for elevation models, UK Met Office for temperature and DEFRA for flooding. This was also put in a time and IPCC scenario context from scientific publications.

The second most important thing  for East Anglia Fenlands residents after the timing of such scenarios, is the actual areas affected by them. Having collected all the underpinning information, it was a matter of overlaying climate data with settlement data: infrastructure was posted in Part 2  from OS Open Zoomstack, and settlements were posted in Part 6 as a local Wikimedia gazetteer.

Update 2: here is a Story Map that explains the background info to this project
Update 3: this Story Map relates flash floods and not river or coastal inundation]

Welcome to new friends

[Update: read here my  new occupation following this]

A fond farewell to two old friends explained my transition to open source platforms. As announced in LinkedIn You can get Andrew out of the geo... (... but you can't get the geo out of Andrew) "Terry Jackson pulled me back in to the publishing business as a data wrangler". What does that mean?

Releasing data really works, Part V

It took five days (after hours) to stand up, learn, tweak and display my East Anglia Fenlands project on Mapcentia's web service. It started with a GISuser group post on LinkedIn on Monday, I used my Amazon Web Service free EC2 trial and GeoCloud2 under beta, and by Friday I had it working and styled. No small thanks to Martin Hogh's original work and help, the result is a simple yet modern and pleasing web map.

Cloud Futures #3: Bridging the Gap

Bridging the gap between desktop and on-line GIS follows the first and second instalment, online vector GIS and spatial data validation. GisCloud introduced a free Esri extension to load features and attributes to its file system. This follows other services such as Arc2Earth and  Arc2Google, except in the vector domain. Having both Esri @ home and a private cloud I put this new extension through its paces.
