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.

"...with a little help from my friends", Part II

James Fee cracks me up every time. First he does not dance on ArcObjects' grave but praises it, secondly he exults Google Earth Builder until he, well, hits nothing, and best of all he sees off Esri's webADF to welcome its REST API. Currently in the business of hosting data on the web, his head is not in the clouds but bolted on tight by business concerns, mostly clients' who gives them a certain sharpness as they're always right, right?

More on time-based GIS

Time-lapse GIS helps clear the clutter of a quarter million points of ship sailings from captain's logs from 1662 to 1855 re-posted last week. As an at-home project I previously split the data into arbitrary half-century time slices to better visualise it all. But that interfered with seeing trends across the span of data.

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)

Arctic Dreams, Part II

As the Arctic comes under more scrutiny in the news, I'm reminded of my visit up there 25 years ago when we actually thought of global cooling! But the issues of access and exploitation are certainly not new... And I posted a few polar maps for fun here and here, though the best rendition can be found here.

More temporal web maps

Here is last year's Fenlands mashup on 2nd gen. beta GisCloud.com (this data is also posted on the UK academic ShareGeo site and the data.gov.uk apps site):

Critical mass, satellite imagery and GIS

Satellite imagery has been around for almost as long as GIS, and the following may just make them so easy they finally gain momentum. The same way Jeeps and Suburbans had been around for a couple of generations, but only the last generation saw Ford legitimize SUVs with its Explorer.

Who said history or surveying had to be boring?

My friend Brent Jones' video is worth watching only for his tongue-in-cheek humour. I thought only Cambridge dons remembered that Newton deemed longitudes NOT calculable! But then along came that clockmaker Harrison, the tinkerer who beat the thinker, as accurate watches made longitudinal calculations possible.

Another Take on Climate Change, Part IV

[Update: Part V, more on polar wanderings]

From guardian.co.uk today: Goce satellite maps the Earth's gravity in unprecedented precision. Aside from updating on Part III of this series, this slots right into my comment on the lesser-know fact that the earth wobbles on it axis, and that mass plate-tectonic movements are the result as well as the cause of earth tremors along plate boundaries

"... with a little help from my friends"

On my 100th posting last week I found some interesting statistics. I use Google's Blogger for its sheer simplicity. And I just found out it offers stats and maps helping track readers.
