Welcome to new friends

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?

Terry came from a web publishing  background in Wales over  a decade ago, when web publishing wasn't 'cool' yet. Now in Cambridge he's setting up a Sustainable Cottenham (SusCott) Google page - it's the second village north of the city, which we both call home now - as a showcase for publishing digital info in aid of local economical sustainability.

Serendipity had it that almost a decade ago, I aided a combined University of Cambridge and Cambridgeshire Archive project, "Fens Historic Environment Project: Understanding the Fens’ past for a sustainable future". FHEP funding was cut by then austerity government, but I proceeded with providing a geo-history background using free open source software and recently released government data. It was the easiest way to engage both stakeholders above into mapping this manifesto - thanks Profs. Sue Oosthuizen and late Frances Willmoth, & PJ Smith for early help with HC Derby data:
The area of Eastern England commonly known as “The Fens” has a very distinctive regional identity, arising from the relationship between its inhabitants and their unique landscape. Historically, it consisted primarily of seasonally inundated wetlands, which supported an economy and society based upon pastoral agriculture combined with fishing, fowling and the use of other wetland resources. Today, however, after more than four hundred years of drainage and “improvement”, the greater part of it is a dry plain and used for growing crops.
 [...]
(b) ‘GIS’ databaseThe creation of a ‘GIS’ database at an early stage of the project will allow any information with a geographical element to be brought together and used for the exploration of spatial, historical and environmental relationships. Older and newly-identified sources will both play a role here, as they will in other innovative developments: for instance, historical findings and archival records may be used to complement the archaeological data of the Fenland Survey. The opportunity for co-ordination and collaboration with other Fens-related GIS ventures of a more limited or specialist kind will be welcomed.
So this dataset slots in beautifully with SusCott's own manifesto. This was a perfect opportunity then to repost as on Google Drive my public (CC BY-SA 3.0) maps & documents, and  on Google Cloud the resulting map for public display on any device - thanks Tom Chadwin for help with web posting:

Note that I promised geopackaging  in my last  blogpost, and so I did in posting said data  here.
Stay tuned for future developments on this fabulous dataset  - how often can  you map a region's economic geography on a dozen features over almost 1000 years time span?

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 as a Story 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 post is the backbone of this story map of the HMS Challenger 1873-1876 Expedition:

Climate change alert

[Update 2: Euan Mearns factoid-checking counterpoint highlights, if nothing else, the Gordian Knot-edness of it all...
Update 1: thanks fellow Canadian Texpat Katharine Hayhoe for her efforts in this document and the twitter-sphere]

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). Do not despair however...

Historic climate data revisited - 4 - polar is POpuLAR

[Update: Part 5 will be the last installment 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.
