Coronavirus time-enabled maps

[Update: thrilled to present at How to do Map Stuff: a Live Community Sharing Event
Update: The Times' Sam Joiner just cleared  England COVID map for London crowding using ridge map animation

Local dashboards updated daily from Public Heath England data are bolstered by other open data: As coronavirus affects most notably the eldest and youngest, Office for National Statistics age distribution is a welcome addition to case distribution maps. A static web map showed cases and age distribution side-by-side - a story map has the full back story on its derivation - Kenneth Field's "coxcombs"  post static time-series that helped identify here vulnerable groups of elder and younger populations, and to overlay them atop progressive case numbers over a set time period.

Update 3: added population by age group for comparison, see bottom of right panel
Update 2: streamlined with one map incorporating all data + complete instructions
Update 1: mobile version added, added Persons Recovered (removed by PHE later)
Correction: user feedback showed importance of symbology to convey information

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

Local Community Engagement 1234567891011, & 12


[ 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.

Flood risk model

Local Community Engagement 1, 2, 34, 5, 6, 7, 8, 910 &11


[Update 1: Part 12 describes Cambridgeshire Parishes affected by sea level rise
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

Local community engagement

[Update 2: we since signed up to an Esri(UK) Nonprofit Programme.

Update: Part 2 builds a story introducing the community.]

This follows my transition introduced last September and last month. I first used Esri  web mapping tools to help me canvass for EU elections in my local community five years ago. I then found local community engagement - online in my old Texan hometown of Houston - 18 months ago with Hurricane Harvey. I presented social aspects  afforded GIS at Esri European Petroleum GIS  conference in London that fall.
