Step through Hurricane Sandy the last six days

NOAA NRT AIRS fly satellites that record cloud cover and other atmospheric sensors described when I tracked Kuwaiti sandstorms. Stepping back six days offers a fascinating glimpse in the progress of the hurricane. Hurry as this posting will quickly become stale-dated as the storm moves off the US East Coast. Here is a presentation built in ArcGIS Online for your viewing pleasure.

Beautiful maps in current affairs

Update: "presentation" link below updated, thanks AAPG Customer Experience Center.

Update 2: that area is still a hot spot (Ecocitas).

At presentation in London on the UN Convention on the Law of the Sea was given a few years ago by Dr Parson of the Southampton UK National Oceanographic Centre. He described how nations were given an opportunity to claim Exclusive Economic Zones (EEZ) beyond the standard 200 nautical mile limit (viz. UNCLOS and UNEP). The reason AAPG hosted this is because most such extensions revolve around petroleum and mineral rights in the Offshore Continetal Shelves (OCS).

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.

Webmaps, history, climate and geology

Chatting with local history buffs brought up amazing facts about climate change and sea level rise since the Middle Ages in East Anglia. One book's sketch map relates how the North Sea coastline differed from today, and how that affected Anglo-Saxon socio-economics there before and after the Norman conquest and the Domesday book.
