More fun with Maps

"I'm baaaack"
After a year hiatus (see here & here), I have decided I'm not leaving the UK after all. As a result:
- on ArcGIS Online look for azolnaiadmin and devzolnai 👉 my Living Atlas contribution!
- I restored my ESRI(UK) Non Profit Oraganization account with Terry Jackson - see cottenham.info in banner ribbon menu - so my story maps and posted maps should all be restored too
👉 my Developer account never left, see my perso. & prof. portfolios, top R on desktop browser - despite news swirling around twitter, I reluctantly rejoined @azolnai, but this time will carefully curate it in the geo space - one issue before, was that I really should've split professional (GIS) and socials (activism) - made it "pro" under Community, but I will not pay to get "blue-badged"!

"So long and thanks for the maps" - Pt. III
Following on the listings in the previous post, lets revisit some blog stats Google handily collects for us! This is an update from two years ago:
... We hit the 13 year and exceeded the half million hits mark!

"So long and thanks for the maps" - Pt. II
Part I announced my exit from social media & web mapping. Here's my topical catalog:

"Something happened on my way north from Londonium..."
... said Caïus, "this young noble went charging by in his chariot, but 20 milia north between the tumulus and the circular fort ruins, I had to retrieve him from the bushes... His chariots had crashed going straight and missing the jog in the road". "Jog in the road?" asks Severus. "Yes", replies Caïus, "the road is misaligned NW and SW at that point, and there's a 20 pedes section at a sharp angle joining them". "How odd" retorts Severus, "We build perfect roads... why that misalignment? Did the Gods have fun and push them aside to catch speeding charioteers? Surely the indigenous, if there are any, couldn't sabotage a road: they barely build huts of reeds, never mind challenging our glorious engineering... Ave, Caesar!", he salutes, "I must go."

Fun with puzzle maps
Look what I found!
Having taken a vacation from work and social media, I found a puzzle box in my late Dad’s old office, while visiting my Mum:

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:
