Satellite data help for local housing issue

 The #30DayMapChallenge Day 23 challenge is "GHSL data", here is the section in the story map that will chronicle the map challenge when it's finished:

Global Human Settlement  for Northstowe controversial development NW of Cambridge UK, monitoring housing probability (GHS-BUILT-S2, 2018) and housing footprint (GHSL-ESM, 2015) against Esri 2020 Land Cover map extract with OpenStreetMap detailed base-map. Various blended overlays 'bake' the layers into a screen pattern allowing to compare and contrast past built areas vs. currently probably built against submissions. 

More map art

A few years ago I used Charlie Frye's online lesson Explore future climate projections to learn how to use NetCDF and map temperature regimes - it's shown below in Patterson & Savaric's Equal Earth Projection. It became the basis for carbon emissions map just updated in the last blog post.

Carbon emissions reloaded

[ Updates:  watch the updated bubble map video wrapping this all up at the bottom! ]

Late 2019 I wrote in A tale of two maps: 

LSE’s Leslie Sklair asked me recently to produce carbon emission snapshots for an upcoming book. I had already mapped CDIAC’s CO2 emissions since 1751, I updated with BP Stat. Review current data, and I created in Esri web mapping platform some dynamic counterparts to Carbon Atlas’ static maps.

 Those 2018 data were recently updated up to 2020, and further fuels listed by CDIAC were added to create this map, using Esri's improved web mapping:

Return East Anglia Peatlands to being carbon sinks

No. 20! Isn't it fitting that chronicling East Anglia challenges & opportunities w.r.t. climate emergency - risk of flooding, sea level rise,  vulnerability indices and now pandemic - uncovered the greatest opportunity yet: returning local peatlands from carbon emitters to original carbon sinks could dwarf any individual effort to mitigate CO2 emissions, currently the major driver of climate change.

 East Anglia Flood Defences Final showcased in a story map the entire flooding infrastructure framework for the region, both from rising sea levels and risk of flooding, complete w flood defence infrastructure.

Online discussions in the wake of the IPCC 2021 report broadened that scope back to an original posting almost two years ago Sea level rise models show ins&outs of climate change science. Here is that update expanding to England and NW Europe, wrapping in all the lessons learned along the way.

[ Update: watch this creepy reprise by Rolling Stones & Boston Dynamics on the 40th anniversary of the Tattoo You album ]

The 25th anniversary of Win95 launch reminded me of the cringy launch party livestreamed where I was then in Calgary. What struck me was in Rolling Stones' lyrics including "you make grown men cry" in the launch party was clipped in later adverts... 

"With a little help from my friends", Part II

New how-to 

Part I showed how a map of DEFRA open data can help situational awareness for a West Midlands XR event. Having done a sea level rise and risk of flooding map for the Thames River valley near London last year, I redid one now with the lessons learned in the interval. The previous Sea Level Rise map from Open Data was rather onerous: I streamlined the process to simply load free & open data with only GIS styling; the resulting Build your own can be replicated on other GIS with listed data sources.

Unlocking Open Data from a legacy site

 In the process of looking at land cover per previous post, I found Natural England's Natural Capital Atlas - their story map encouraged me to enter EsriUK's latest competition - their Esri dataset is accompanied by ample documentation under data.gov. To save us reverting to ArcMap, let's use the provided layer files and a file geodatabase in three simple steps to map our own region on ArcGIS Pro.

Update 2: see next how to re-use, clip & correct Natural England's Natural Capital Atlas

Update 1: added Living Atlas, ESA & USGS land cover and Natural England peat lands ]

Having concluded a comprehensive synopsis on risk of flooding and sea level rise, an opportunity arose to look at land cover classification with the data below and two peat land experts who will help with this.

What is your 'ikigai'?

 Ikigai (生き甲斐, "a reason for being") is a Japanese concept referring to having a direction or purpose in life, providing a sense of fulfillment and towards which they the person may take actions, giving them satisfaction and a sense of meaning. en.wikipedia.org

"With a little help from my friends"

[ Update:  Part II re-uses this and improves the manual for a London area action ]

Part of our mandate at cottenham.info is to raise awareness around climate change issues in East Anglia. A key part is to quantify risks around flooding from land during increasingly variable weather, as well as to predict what sea level rise would look like over time from melting polar ice caps. That combines respectively excellent ground work by DEFRA - see their Future Fens twitter feed - and modelling against topography by Ordnance Survey and DEFRA. And timing of sea level rises is an emotional issue: to balance the reality of the risk with questions around time scales (see comment), will help raise awareness without unduly raising alarm.

Cambridgeshire COVID Info Portal 1¼ years later

Almost 1½ years from the onset of COVID, here a video of the info portal created using ESRI dashboard, inspired from the Johns Hopkins University pioneering hit - same tech with more data and expertise - our own info portal is a handy  bit.ly/CamCOVIDinfo.

 This update to Challenger Expedition DIY Web Map is called an "inchworm" map, as monthly points appear to worm around the globe, with an inchworm's hump at times. This caught @miniboats eye on the approach to the expedition's 150th anniversary (see also a fascination Natural History Museum post here).

This closes the trio of updates on sea level rise timelines and infrastructure based on newly available climate change data, since this project started two years ago. 

Environment Agency's DEFRA not only manages a comprehensive Risk of Flooding for River and from Sea via ground observations and mapping, but it also manages all the infrastructure related to flood risks from the same. 

Let's extend our ongoing mapping effort here to include AIMS Spatial Flood Defences (inc. standardised attributes):

Following on the previous timelines update focusing on Cambridgeshire & Peterborough Combine Authority, this is an East Anglia-wide update based on Environment Agency (EA) Survey,  Office for National Statistics (ONS) Geoportal and Ordnance Survey (OS) Open Zoomstack data.

After a hiatus focusing on Coronavirus and story maps on East Anglia and other mapping topics, let's revisit that moving target of sea level rise timing. 

Tree planting survey - Part II

[ In the news: ‘Amazing success’ as community group plants 165 trees by banks of river Cam ]

The previous Tree planting survey 1-2-3 showed what3words used to located and post on a web map rough surveyed locations for tree planting directed by a tree surgeon, to help restore tree rows along the River Cam towpath immediately north of Cambridge UK. The beauty of turning out a web map the same day as the survey, is that shortly after, printing out the same map for tree-planting volunteers to take into the field was feasible almost as quickly. So after a 'high tech' Part I, here's a 'low tech' Part II.

Tree planting survey 1-2-3

[ Update: see next the fieldwork preparations that went on as a follow-up to this project 

Update 2: See also other prior actions & concerns by same group here ]

New Flamingos, my Extinction Rebellion group in Cambridge decided to do a little outreach - not unlike my other group On the Edge that engages with my village around flood preparedness - we work with the community to replant trees along the left bank of the River Cam immediately North of Cambridge UK. This afternoon, a tree surgeon accompanied our survey along the river bank and suggested tree location and density as we walked.
