Black Monday? (repost LinkedIn Pulse needing login)

OilPro posted yesterday on the Monday oil price route and suggested that oil may settle nearer $40 a barrel. Euan Mearns earlier wrote on the trials & tribulationsof oil price predictions, his sophisticated study concluding that #itscomplicated. And Paul Hodges chimed in the same on OilVoice.

On the other end of the scale I simply tracked the price of oil from bp Statistical Review of World Energy that provide, among other things oil prices back to 1861. I used it to illustrate our industry's need for innovation, as well as a backgrounder for my AAPG Visiting Geoscientist lecture this summer.

Excel's simple trend line analysis had an interesting 5th degree polynomial - note this is pure number crunching - no framework industrial or statistical:

I clipped oil prices in 2014 US$ for the last 50 years, and the trendline shows a sharp dip. Balderdash! you might say... But adding OilPro's prediction for this year, that extra number however soft gave the same trendline:

In no way does this replace others' erudite treatment of the oil price game, but doesn't adding a number that preserves a trend give credence to that trend?
Only time will tell whether we can feel bullish about the market , or have to whip it into shape like the station hand* atop.

A day in the life of a petroleum professional - Part III - shorthand

This is Part III of a "A day in the life of..." posts, to introduce basic petroleum data management for professionals who generate prospects. This is a yet even simpler workflow that helps rapid project start-ups for propectors rather than data managers.

DaaS BooT (Data as an Asset, Part II)

[Note: this is a re-post from LinkedIn Pulse that requires a user login]

After Das Boot - German U-boat disruptive technology of WWII - it stands here for Data-as-a-Service, Business Opportunity of Things - rather than Internet of Things (IoT); it underscores that without business outcome, we might as well stay home: that is the tenor of GEO Business 2015, in its third year, as it draws together Surveying, BIM, GIS and business.

A tale of two cities, or Bauhaus for maps

I attended two shows back-to-back in London yesterday. Esri(UK) Annual Conference was daytime at the QE2 Centre in Westminster a stone's throw from the Parliament. London Geomob was that evening in Shoreditch, the swanky London digital hub where Ordnance Survey just opened the Geovation Hub.
If the 20 min tube ride in between might have been through a wormhole, such was the contrast, both meetups strove to do the same thing, substituting maps for arts as the Bauhaus movement"founded with the idea of creating a 'total' work of art in which all arts, including architecture, would eventually be brought together".

Wikimedia European History Map over almost 2500 years

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

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.

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 - 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.]
