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.

Temperature - Mean Annual Baseline

Also recently updated my story map Maps like 3D prints with so-called emo or goth effects using John Nelson's Ice Mountain (lighter emo) and Sunrise Hack (darker goth) for a series of my favourite places on Earth. I tried another of his 2.5 Posters on a NW England dataset, tho DEFRA's incomplete DEM coverage created mixed results, show at the bottom,  Maps like 3D Prints - II (go to Poster). Recently John Nelson also reverse-engineered an illustration to create a DIY Graphic Design, using this time Tom Patterson's Natural Earth data in addition to Living Atlas terrain layers. 

So I took Temperature - Mean Annual Baseline from the lesson atop and smashed it into John's Graphic Design above. The reddish hue created a purple foggy effect offshore and ruddy shading effect on land: I simply took all the layers in the video above, and added the temperature layer just above Patterson's land use layer. To better display all layers, neither Global background not Watercolour paper special effects were used:

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

Community Engagement 12345678910111213, 141516171819 & 20

[ Update: added "Why we should all be obsessed with Peatlands. | Ireen van Dolderen | TEDxAUCollege" ]

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.

Sea Level Rise Maps #reloaded

[ Update 2: at bottom is the comprehensive water web map that followed this...

Update 1: near the end of the story map, see how you can style your own DEM tiles ]

 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.

'Emo' vs. 'Goth' map looks

Recently updated this story map Maps like 3D Prints: Emo or goth? A map tour of special effects - adding to existing Ice Mountain hillshade style (augmented with Misting - the Emo part), a Sunrise Hack (in fact more like sunset - the Goth part) - all John Nelson's on Esri Living Atlas Terrain layers.

"Start me up" reloaded

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.

Land cover to study East Anglia peatlands evolution

Community Engagement 12345678910111213, 1415161718 & 19

[ Update 3: next installment integrates this + companion below in peatland assessment
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
