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.

GIS education & awareness

There is a patent need to better explain all things geospatial to us as geo professionals as well as to the public addressed here.

A fond farewell to two old friends

Over seven years after starting to post on arcgis.com and almost five years after posting mega-datasets on GeoCloud2 via AWS, I have to seriously reconsider my investment in web data. I already mentioned my new direction two posts ago, and now stood down my AWS instance - thanks @mhoegh for his help on Mapcentia - and I will let my arcgis.com account lapse next May, five years after it was created (I already rationalised my Esri accounts, hence the two year gap with opener).

Historic climate data revisited - 4 - polar is POpuLAR

[Update: Part 5 will be the last instalment as mentioned at the bottom of this blog-post]

Having explored polar maps here, here and here, was it ever a delight to find one of the earliest maps in that same projection! In This Is the World's Largest and Oldest Map, Culture Trip report how David Rumsey recreated a digital copy of a 1587 map from Milan in no less than 60 pieces:

Comparative economics England & Wales since the Middle Ages

My latest post of the 7-part series Toward a rational View of Society on my personal Medium channel, follows my previous maps here of medieval & later drainage of the East Anglia Fens.I expanded a little on the economics in the concluding paragraph in this short presentation.

More polar 'map porn'

[I stole the second half of the title from Reddit group of same name.]

From previous blog posts on Arctic polar maps here and here, let me share two more maps found via my favourite Facebook group Remembering the Franklin Expedition.

Historic climate data revisited - 3 - circum-Arctic update

[Update: Part 4 provides a further update on platforms available to map polar data]

In my previous blog, how many layers can be combined in an arresting polar Arctic view. They show the almost zero overlap of historic and current weather and climatic data. They herald the importance of oceanic climate data going back before 1880, when any weather data get scarce.

"Horses for courses", part II

previous post here contrasted full professional workflows for petroleum geology students, with very simple analytical tools for a businessman looking to ascertain population density. As my subsequent posts show, I have an interest in Antarctic and Arctic maps, history and climate; you can see my case against the popular web Mercator for polar regions in this map story.

Historic climate data revisited - 2 - circum-Arctic

[Note: Part 3 adds World Port Index data compared to historic Gazetteer
Follow-on class materials the last two blogposts generated are posted here.
Go also to section 5: Arctic / Antarctica GIS application, of 1000 GIS applications ]

Following on the Antarctic blogpost, I took my lessons-learned to the antipodes for these reasons:
