The areas with no lines - that's areas without ANY infrastructure or just areas where OpenStreetMap has no data?

#32Earlier quoted context omitted.
Used to? A lot of that still happens, just instead of "terrorism", it's "crime". FOIA requests for locations of camera, alpr, and other massively used and unaudited surveillance equipment are routinely denied because it will "allow criminals to circumvent". It's all silly and benchmark moving.
Yes, used to. 15 years ago trying to publish research on critical infrastructure vulnerabilities would get you a visit from the FBI (ask me how I know). Now you get invited to DC to present it in person and your remediation suggestions are taken seriously.
...that still doesn't mean they've stopped as a practice, on the whole, or through other intimidation methods. Hell, I'd argue that its current and subtle manifestation is more harmful on-the-whole than it used to be. Like, sure, the DHS voluntarily releases information, but that's discretionary and at their will. Eg, I sued the Chicago for database columns and table names after they argued it would be a security risk -- DHS gives that info about their own systems voluntarily. And that's even with case law from an ICE lawsuit that says schemas are exempt.

#33What a fantastic site.
I was surprised to see that India appears to have a denser web of powerlines covering more of its area than the US and was wondering if this was a difference in data, but no, Wikipedia confirms:
> on average there is at least one HV line within a distance of 8.15 km) over the entire area of the country. This represents a total of almost 20% more HV transmission lines than that of the United States (322,000 km (200,000 mi) of 230 kV and above). However the Indian grid transmits far less electricity.

#34So much geo stuff on HN today! hallelujah
Exactly, I already booked marked 3 maps in 10min!

#35It’s great, gives a really good perspective about infra, and shows how Canada is basically like a a medium -or less state compared to the US.

India is about 1/3 the size of the US but with 4x the population.
So India is effectively 12x more dense/person/sq.km. than the US.

#37If you're interested in mapping infrastructure, you may like Overpass Turbo.
It maps all kinds of stuff, selectable via queries, such as water fountains, parking lots, etc. I've always thought it could come in handy during times of emergency, such as if FEMA needed to inform citizens of certain resources in their vicinities.
Example 1] - Defaults to amenity=bottled_water -- Search & select "San Francisco" and click "Run" (Click "Load" for other demo options.)
[Example 2] - Parking lots in SF https://help.openstreetmap.org/questions/67865/overpass-turb...
Example 3] - Go back to the default example of bottled water: click "Load" --> select the "bottled_water" example. Now change [amenity=drinking_water] to ["shop"="butcher"]
[Example 4] - Multiple nodes, as categories of suppliers -- Paste this into the Overpass console: https://pastebin.com/Q4X2YPvj to see nodes where shop=butcher, farm, agrarian, greengrocer

Probably both, but note that a lot of areas only show down to 115kv which excludes all the distribution lines that feed homes and businesses.
Re: Open Infrastructure Map
#39Interesting to see that electric grids end at many country borders, e.g. China has just a handful of ties with Russia, none with Kazakhstan. India and Pakistan have no connections, just as India & Thailand. Pakistan has no connections with Iran. Vietnam & Laos border is clearly visible too.
There's still a visible border between East Block and their Western neighbors in Europe, and a little bit of exUSSR border (e.g. Belarus & Poland).
Re: Open Infrastructure Map
#40Love this! Would be even better if there were labels / wiki links on the infrastructure. For instance, there's a huge pipeline across Asia, and I'd like to know what it's called,
Wikimapia has some of those, with links or sometimes descriptions with photos.
