GIS for oil spill modelling - Part II

This is a follow-up to Part I explaining oilspill modelling using NOAA Gnome modelling software and Kuwaiti ROPME data, all in the public domain. This has now been posted on ArcGIS Online as a time-aware file geodatabase map package. In this video using a dark grey basemap, the map package shows mock oil dispersal via advanced annotation, inversely proportional to time.

GIS for oil spill modelling

Presented almost five years ago to Kuwait Petroleum Company with local Esri distributor OpenWare, using NOAA oil spill model results in Esri GIS and recorded in YouTube. [The presentation has been updated to reflect additions in Part II.]

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.

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

[2016 Update - PUGonline Geospatial Workflow catalog summarised this as: Development & Planning > Mapping Well Data

2015 Update - A higher level article is published by PPDM Foundations in its Q4 2015 issue]

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 prospectors 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 - 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.
