Digital terrain models help create a picture - Part II

[ Update: see new arcgis.com interface for another view of this here & under Update 5 here ]

The previous post showed how digital terrain, surface (add buildings & vegetation) and elevation (detail topography) models highlight geomorphology (land features) and infrastructure (roads, canals etc.). That was in the Cambridgeshire area of the southern Fenlands of East Anglia, as a complement to sea level rise models from coastal inundation, as well as flood risk maps from rivers and from sea.

Digital terrain models help create a picture

[ Update: next post discusses same in the East Anglia coastal area of the Fenlands ]

The previous blog showed how to effectively portray coastal inundation, as it progresses inland from the encroachment of sea level rise. These were base on 30 m. resolution Digital Elevation Models (DEM) from OS OpenData as explained previously here.

Low tech / high tech map updates, Part II

[ Update: the next blog details and updates this via a story map and new data ]

Part I showed how high contrast map symbology of Sea Level Rise can be transferred to a paper map to take around events. When asked if I could scan and reprint that paper map, I thought: why print a hand-transfer, why not print the digital original? Better still: why not try and enhance that digital map to really give an impression of sea level rise gradually invading the land?

Massive online activity - all is not as it appears - More

[Update: another thorough review and insider's view of same on LinkedIn Pulse
Update2: and a follow-on Pulse post also, prompted by a comment on yet another]

This is one more follow-on to the Pokémon Go series, which suggested we cool our jets. In my previous post, I compared Pokémon Go to sandbox video game MineCraft, online game Foldit that helped crowd-source the resolution of complex protein structure and Sim City the granddad of virtual worlds. Here are juxtaposed in Google Trends their search hits as a measure of interest in these.

A question of business models in webmap offerings

Eighteen months ago, Google quietly deprecated its Maps API, and ESRI offered and alternative with ArcGIS Earth, then Mapbox and Carto in quick succession: I blogged then Esri, Google and if the shoe fits... Part 1 and Part 2, mirrored on LinkedIn here and here, respectively. Safe Software, LINQ Ltd. and I basically saw it as the next phase in the battle for The Internet of Things (IoT), which has been gaining traction of late.

[Update: interesting tweet exchange w @0mgould at bottom]

I wrote over the past weeks why Pokémon Go is not what it seems:

• from being hailed as the next big thing in geospatial (neither open nor intended to be)
• to hiding the access / marketing in&outs its hosts indulge in (internet privacy anyone?)

Update 2: follow-on posts here & here on geo-ramifications to virtual reality mapping]

I posted last week re: spatial ownership issues Pokémon Go raised, from the personal (visiting family the weekend it was released in France)

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.]

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.

Maps are forever (Part II)

I wrote earlier about a 1610 map from the Harvard University Library of the Cambridge UK region, a snapshot of which I simply edited the tear and restored it by eye-balling it in Photoshop Elements. I detailed before some local history and geology too.

Local maps one year on from Kuwait

Hard to believe it's over a year since I left Kuwait, and I'm back in Cambridge now working west of London - the shortest commute yet, weekly as opposed to every 10 weeks in Kuwait or every two weeks in Milan three years ago - so just out of curiosity I looked for web maps of the area again.

Petroleum GIS then and now

Exprodat published a free eBook: Why use GIS in petroleum?, an excellent state-of-play as well as good industry marketing to augment their impressive blog. Does their Figure 1 not have a certain air of déjà vu, however, compared to Figure 1 of my article in CADalyst written 25 years ago?

East Anglia Fenlands wrap-up

It may be time to run an overview, two years on this personal project on East Anglia, the last step of which was reviewed by socium.co.uk:

Guns & Roses, or: 3D GIS anyone?

[Update 2: layer package can now be found as Teapot Dome Six Pack on PUG Online
Update: RMOTC was sold off in 2015, their ftp site is now gone, ask for available copies]

The Guns part is the colorful history associated with the Teapot Dome. A remote Wyoming oilfield once a sleepy Naval Petroleum Reserve, the Teapot Dome Scandal was, however, the biggest to rock Washington DC until Watergate... or the oil industry until the Enron collapse! Read this introduction to a book excerpt: Marines Invade Wyoming - From the Halls of Motazuma to the Oil Fields of Teapot Dome, for cape-and-sword intrigue from ranchers and oil barons to US senators and the White House...

Your team is your friend

I am so proud of my teams at client sites and in our office! One team achieved in 6 months at one site what many thought would take years - to integrate surface and subsurface exploration and production infrastructure for an oilfield in 3D+time. Another team created just this week a real-time GIS data capture system that reduces to 4 steps what took 10 on paper - and of those only the first one is manual.

Social media at work

I've been a LinkedIn member for over six years and have learned to use Groups by now. It's a great place to ask questions among peers, without bothering others who aren't interested in that singular itch of yours. While unfortunately used at times for trawling emails or marketing shamelessly, every once in a while I run across a brilliant idea. Robin Wilson a student at Southampton University, UK, posted the free GIS data links he found and simply asked for more on LinkedIn's GIS group. Well! to date he got almost four dozen replies and he'll post the results here.

Even more temporal maps

I posted here my webmaps from the East Anglia Medieval Fenlands project. I have now posted these on arcgis.com for use in ESRI maps: Watch future posts on time-enabling this project, and adding geo-processing to further examine these derived data. Note also that ArcGIS is available for personal use an research for $100 worldwide now.

Baaack in the arcgis.com

[rhymes with: Baaack in the USSR] After a brief hiatus trying my hand outside ESRI, I'm baaack... posting maps on arcgis.com. Daniel Schobler from ESRI(DE) Schools Program kindly reposted and time-enabled my Global sailings, captains ships logs 1750 - 1850 into his Explorations and voyages 1662-1855 (time-enabled)

Reading Social Web Maps

Look at this map, and what it doesn't show is as instructive as what it shows. You guessed it, it's the low number of social media hits - anyone on the blogosphere or twitterverse would find those numbers on the low side, especially considering the passion current events in Egypt generated on the ground and online - and I wager doesn't reflect poor map making, but rather the fact the web was tampered with during the events in Egypt.

IQPC show in Kuwait City

Attended this small and personable show and met some friends old and new - vendors were invited into the talks and plenty of time was left in between to meet&greet.
