My adventure with Storm Fionn

As Storm Fionn wrought chaos in England and Cambridge, here's my adventure in returning a rental car this morning.
Storm @ 3am 18 Jan with 45mph winds / 60mph gusts in East Anglia - http://bit.ly/2mJybNZ (click to enlarge)

We had rented a seven-seater to go to a funeral yesterday, and I never made the short trip from home to Cambridge Car&Van Rental in time for 9AM drop-off today, straight down the map below.

Google Maps, modified (click to enlarge) 
  1. First I arrive at Waterbeach and cannot turn South, as the road in red wiggle above is closed
  2. so I turn north instead, stop @ 8am to call the rental asking that I return it by noon after class
  3. as I had my first uni. class to attend for note-taking, I hoped to get there the long way around
  4. Google Maps traffic showed that the A14 the straight red Y is also blocked, I went X-country
  5. but even with relatively quiet traffic there, I never made it to W Campus until 9:30 mid-class
  6. so I give up, notify uni. I cannot make it, and head back to filling up and returning the rental
  7. I drop the car off at 10am and return home via Waterbeach, again tailbacks put me there 10:30
  8. ... that's exactly four hours after I turned north in Waterbeach toward my adventure X-country
  9. normally 7.5 mi. (12 km.) to the car rental, and 4 mi. (6.5 km.) to W Campus, take 20 min. each
  10. and the 51 mi. (82 km.) round trip normally takes 1¾ hrs. in normal traffic, under half my time!

Mind maps for GDPR

General Data Protection Regulation will come to European Union five months from Christmas! You will have read of it no doubt, if not, links are in presentation below: Up to Slide 10 is a simple set of tools - mind maps - to get started on this complex process; after that is a suggestion for further help.

Vectors are your friend, Part III

Esri just updated its World Vector Basemaps (v.2). I updated below the notoriously complex and details Aalan Archipelago offshore Turku, Finland. I contrasted in this blog 4½ years ago posting the GSHHG world vector dataset in giscloud.com, a web vector mapping system, and ArcGIS Online, richer in data but then in raster. See an OpenStreetMap backdrop earlier in my companion blog.

Free tools & data to predict hurricanes

Four weeks ago I blogged here about the availability of open data, posting it on the open web and its potential social impact. Two weeks ago I blogged here too about tracking three hurricanes in the Caribbean via the brilliant but closed earth.nullschool.net. In between I compared & contrasted open & closed regimes on my Medium channel... and that 2½ yrs after a previous blog here on same!

Trio of Caribbean Hurricanes early Sept 2017

Evolution of Hurricanes Katia, Irma and José, and of Tropical Storm 57. Note how:
  • Katia developed late over Gulf of Mexico & stops shortly after head-on landfall
  • Irma is the strongest having developed over warmer S Atlantic then Caribbean
    • weakens to Category 3 on first Florida Keys landfall
    • strengthens again over western Gulf of Mexico 
    • immediately weakens at second Florida Coast landfall
    • still Cat2 (not shown) then finally Cat1 before degrading
  • José stays strong over water, strengthens briefly to Cat4-5 then swerves to W Atlantic
  • Tropical Storm 57 never materialised into a possible and feared hurricane three-punch
