Stumbled across this really cool Wikimedia Atlas of European maps. Downloaded the images that seem to come from one Atlas, or are similarly styled and in Lambert Conformable Conical projection. I rubber sheeted them in Esri ArcMap and composited each map sheet in YouTube - if you squint you'll see the four red dots I used as projection reference.

[Update: Posted a "how-to" on the companion map blog for longer pieces, enjoy...]

Releasing data really works, Part VII
And now for something completely different - the original posts until Part VI are listed below - I ran across a nice map of Steve Feldman's: He also tried out free data and software to map UK flood maps, an up-scaled version not for professional re-use.

New business, renewed website
[Update: find on my map blog the full story on how the video below was created]
Since www.zolnai.ca will be the landing page for my new business, I spruced it up to reflect my new brand. zolnai.ca is indeed now registered in England as a Sole Trader.
The banner has been changed to show some example web maps created since 2006, a topic will be renewed at center page, and the navigation has been improved.

A day in the life of a petroleum professional - Part II - shorthand
[Update: posted here an even simpler workflow that reads government data direct from web]
This is Part II of a A day in the life of posts, to introduc Basic petroleum data manipulation for professionals who aren't data managers. This is however a much simpler workflow that lends itself more to rapid project start-ups for petroleum rather than data professionals.

Esri, Google and if the shoe fits...
[Update: a Google business partner's view of things, 3 mo. after the fracas]
[Here is a further update based on input from other people on what is surely a timely topic. Originally posted on LinkedIn Pulse as The (Geo) Internet of Things, it's posted there for a wider audience.]

Personal portfolio of Esri maps
As I went solo in the new year, I collected my previous works also seen in the banner map gallery, and posted the Esri maps as a map story. Go here if it's too slow to load.

A day in the life of a petro-data manager - Part I - Shorthand
[Update: a simpler workflow that uses for-fee & for-free software is posted here]
After intoducing the process to extract, transform & load (ETL) www.boem.gov well data into a www.ppdm.org database, here is the short version expanded over on my sister blog.

Web Maps on Steroids, Part II
I showed a couple of months ago ways to post mega-datasets online without choking the system. This month OSGeoUK gave me the opportunity to present the same on PostGIS Day 2014, as postGIS was the backbone of two of these examples on GIScloud and GeoCloud2. Thanks to OSGeoUK and British Computer Society for hosting this.

A day in the life of a petro-data manager - intro
[Update: Talend made the early version complex, so simpler one was posted later]
Have you ever been given plain text geodata and wondered how to database and map it? And has this happened to you lately with tens of thousands of lines of data? Well help is at hand! Here is an ETL workflow (extract, transform, load) useful to any data manager in or out of petroleum using free tools:
