Local community engagement, Part 5

Part 1 introduced this project to engage local residents in villages north of Cambridge UK. Part 2 elaborated on some resources available and communication via Story Maps. Part 3 looked at three more resources, introduced an open call and closed with an Elevator Pitch. Part 4 looked at community engagement's key differentiator, to search for local info your way, not the search engines'. Let's round this off with our own gazetteer, and then touch on issues around sea level rise maps.

Wikipedia Gazetteer

With my cottenham.info partner Terry Jackso, we completed a Cambridgeshire gazetteer from Wikipedia data! Click on View larger map  and select any town to pop up a full suite of associated information...




Cottenham2020 are a social enterprise keen on linking villagers and businesses for the better good. The context for this is climate change, and local environmental groups such as SusCott are among our partners. The neighbouring village of Histon&Impington just declared a climate emergency. Sea level rise maps are thus part&parcel of the environmental hazard assessment... but we have a surprise!

A tale of two sea level rise models

[Update: submitted the coastal inundation map at bottom, drawn up with ArcGIS water-colour style, as a map and art version to 2020 GeoHipster Calendar competition]

Part of the climate change risk&mitigation efforts revolve around coastal inundation. I first mentioned this almost a decade ago , when I highlighted flood.firetree.net sea level rise map based on NASA SRTM data. A more recent spectacular example on the same data is shown here.



I could not, however, source the original NASA data - an issue around openness and web services discussed five years ago - but I did find a version of it on Esri's Online platform. Toggle on the  WWF / NASA 4 and 11 m. sea level rise below, and see half of Cambridgeshire inundated!



When I was doing Arctic sea ice maps, however, I found NGDC-based CReSIS sea level maps. Desktop mapping showed me a far more conservative coastal inundation of East Anglia: measured from 1 to 6 m contrasts with the 4 and 11 m above. Luck would have it that @kennethfield  I follow on twitter already posted the 1 and 5 m global sea level rise. Toggle those two on in the map above, and you'll only see the north tip of Cambridgeshire inundated!

Note: both Firetree and CReSIS maps were created in 2006 and 2005 respectively, before this became a hot topic, unlike the Risk Zone Map very much in the news evidenced here.

This highlights the issues in modelling. Do consult the sources in my East Anglia sea level rise map. On the NASA side, incremental sea levels are intersected with SRTM topographic data to derive inundation zones (any SRTM data below incremental sea levels is marked blue as under water, any above are left clear as above water). On the NGDC side a two-step raster modeling procedure run atop GLOBE and ETOPO2 elevation data models flooding scenarios.

Posting on flood data interpretation a couple of years ago will show how complex an area this is, like anything is around climate change written up on Medium here.

Local community engagement, Part 4

Part 1 introduced this project to engage local residents in villages north of Cambridge UK. Part 2 elaborated on some resources available and communication via Story Maps. Part 3 looked at three more resources, introduced an open call and closed with an Elevator Pitch. Let's look now at community engagement's key differentiator: Search for local info your way, not the search engines'

Local community engagement, Part 3

[Update: please see the follow-up post expand on our aim in community engagement.]

Part 1 introduced the project to engage local residents in villages north of Cambridge UK. Part 2 elaborated on some resources available and communication via Story Maps. Let's look at three more resources, Three I's of County Planning,  Top Ten tips for Policy Mapping and Smart Cities are decades away but open cities are within reach, then introduce OpenActive's open call, and close with an Elevator Pitch coming from all this.

Community, climate and maps (updated)

[Update1: Northwest Passage: Maps and words adds more illustrations and better maps
Update2: see also this video Arctic Sea Ice Summer based on improved maps above
Update 3: further story map Fire & Ice - Arctic past and future climes focused onshore]

You know you're onto something when your activities converge like so:
  • ever since geologising in the Arctic 30 yrs ago, about the time of initial finds of Franklin lost expedition by Owen Beattie
  • finding out while up there that there was a cat&mouse game between Americans and Canadians over the Northwest Passage
  • recently mapping historic tall ships climate data, as a complement to more recent & land based data, now that it's absolutely critical we better understand climate dynamics
  • using a sea-level rise map resulting from polar ice melts to raise awareness of the climate emergency at a recent Extinction Rebellion event in my hometown

Local Community Engagement, Part 2

[Update: please see the follow-up post as we build a story introducing the community.]

After introducing this social enterprise, let's look at some progress: We joined the Esri(UK) Non Profit, Ordnance Survey Data Hub and Open Street Map programs, all designed to help communities'  open data initiatives key to the next economy.

Local community engagement, Part 1

[Update: please see the follow-up post as we build 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.

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?

Dynamic maps - finis

My last post on dynamic maps and its preceding project recap five years ago outlined how I used ¼M point free-to-use dataset on global historic shipping and climate data. This is the original video of ships'  locations produced a decade ago on Esri ArcMap:

Challenger Expedition DIY Web Map

The last two blogposts showed how to create correct polar maps in ArcGIS and QGIS: here from publicly posted class notes blogged, and here to create simple climate & vegetation maps in ArcGIS Online (AGOL) from Esri Living Atlas data.

Let's look at now creating complete maps in AGOL from publicly available data, and analyzing it over time to see their historic significance. This results in this web map of the HMS Challenger 1873-1876 Expedition:

Arctic wrap-up as a story-map

Following my previous posts on geo-awareness and transitioning platforms, I repost here this story map that wraps together the story for the Arctic region on Esri platform. You will find at its end a link to the course that cover both poles on Esri and QGIS as complete exercises in polar mapping.
You may wish to zoom in to polar views one or two steps for a better view: it's an artifact of the largest data-set used in the web map app.
