The sun never sets on the languages of London
London’s second languages: English is the dominant language across all areas of London* but this map shows those locations where the second largest main language is spoken by 5% or more of people living there.

10:42am 6/6/2013 changed “Other European” to “Yiddish” as per the Census sub-category
There is a pocket of primarily Yiddish speaking households in London.
That makes me think of my grandparents. I wish they could see this map. They would smile and laugh. I miss them.
Some lakes are black in Google Maps
View Larger Map
Why do some lakes appear black in Google Maps?
It isn’t due to extreme cold, nor latitude, I don’t believe. The body of water in the embedded Google Map here is in a very cold area, e.g. -20 F average winter temperatures, in the northern part of Canada’s Northwest Territories. Yet even chillier bodies of water are blue e.g. in the Arctic Ocean, some distance due north.
- Incomplete data Remote bodies of water such as Great Bear Lake, are probably not supplemented by additional data beyond satellite images. Counter argument The same might be true for the Arctic Ocean, yet it is not black! Response Google might have decided to just color that in, in shades of blue, as the information isn’t going to be relied upon by Google Maps users to navigate the Arctic Ocean. In contrast, there is a possibility that Google Maps coverage of Great Bear Lake could be used by hikers, which probably isn’t advisable. When seeing it in black, casual hikers might be more likely to check with local Canadian civil authorities for weather conditions and suitability for visiting, precautions advised etc. which is a good idea, and safer for that locale!
- Water depth? Maybe, but the Arctic Ocean should be as deep or more so than Great Bear Lake, I think.
- Censorship or sensitive information pertaining to Canadian (and U.S.) national security Unlikely, for many reasons. It is a big, cold, remote region.
- Something else entirely? Probably… but what?
The North Pole

This is a follow-up, written by me (full disclosure) to the recent New York Times Borderlines Opinionator post, The First Google Maps War.
On the hazards of crowd-sourced reference tools
This is problematic, whether open data e.g. OpenStreetMap, or not e.g. Google Maps with new commercial rate charge for high API usage.
Either OpenStreetMap or Google Maps is probably just fine for FourSquare users. But the same isn’t true for setting territorial boundaries in Asia, or South America. Nor for disputed street names in a small Vermont town, either.
Earthquakes and nuclear power
Seismic activity and U.S. nuclear power plants, data visualization app is Insight by Rhiza Labs
I don’t know if this reveals anything or not. The first (and only) thought that occurred to me was that it was a good idea that no one decided to build any nuclear power plants along the San Andreas Fault. Other than the two reactors in California, there are hardly any nuclear power plants within 1000 miles of any high seismic activity areas.
I just had a silly thought
What if I interpreted this data visualization to mean that nuclear power plants dramatically reduce or even stop earthquakes? After all, who is to say in what direction the "causally correlated" data should point? Just think of the action item that would suggest to policy makers!
Ignore the fact that seismic activity was already well-known and recorded by the time nuclear power plants were built. Presumably, it was taken into consideration as a risk factor by those who were making decisions about where to build them.

Mapping the geospatial domain
This site is awesome fun!
from the Institute for Enabling Geospatial Scholarship -
"a community-driven resource for place-based digital scholarship"
This is a lighter-weight, more fun version of OpenMap. Well, it was fun for me.
If you ARE interested in opensource data for geo-spatial applications, this is the kind of thing that one can do with OpenMap.
You can also go on their site and label the name of the street where you live and other geodata points if no one else got there first.
Most of Phoenix, Arizona is virgin territory, ready and waiting to be mapped.
WhyNotTheBest.org was created and is maintained by The Commonwealth Fund, a private foundation working toward a better health system.
It is a free resource for tracking performance on measures of health care quality. It offers the ability to compare hospitals and facilities with peers, on a range of benchmarks, and over time.
The site includes publicly reported measures of hospital quality, the same as those reported on by the Centers for Medicare and Medicaid Services. Data is updated four times per year, includes nearly all U.S. hospitals, over 4,500.
See Methodology for specific details.
