On laptop browser:

Google Maps Brisbane: shows no lights. (Also not on the phone app.)

OSM (Open Street Maps) Brisbane: shows lights, seems accurate near me.

Google Maps Osaka: does show lights.

OSM Osaka: does show lights.

Google shows some that OSM doesn't, and I don't recall which is accurate. OSM shows one that Google doesn't, and in that case I'm pretty sure Google is right, I went through there a lot and recall no light.

...Google has Street View, so I can check that there is in fact no light, or wasn't a year ago. I wonder if I can update OSM. ... oh wait, OSM calls it a 'blinker', and now I do see a single light, yellow in one direction and red in the other. Like a power-hungry yield and stop sign combination?

Both show pedestrian overpasses but OSM has better visual contrast.

OSM seems more regular in showing street names... I've often been annoyed by zooming in and out, trying to get Google to tell me what some street, often major, is.

There's this bizarre thing where the makers of globes don't date them. They'll put a copyright notice on, I'm looking at "Copyright by Rand McNally" right now, but not the date of the copyright or when the globe was made. Not. A. Single. One.

Which is annoying in terms of data transparency, but does provide a fun game of "can I figure out the period this globe describes?" from looking at the countries. S had an old globe with steamship routes still marked on it; the Central African Empire alone pinned it to a three year period, and the independence of Dominica (not the DR) helped give a Dec 1976-Nov 1978 range.

The place I'm staying right now has an even older globe, with FRENCH WEST AFRICA sprawling over it. It's very detailed, with all sorts of obscure towns, and plane routes, maybe steamship ones. Occasional "highest waterfall" notes, an explanation of the International Date Line, and the solar analemma.

But when is it from? That's actually a bit ambiguous; with the help of an online acquaintance making suggestions, I have it down to Feb-Dec 1958 *or* June-Dec 1959. There are lots of constraints giving a 1958-1960 range, but a couple of conflicting points.

Singapore lacks any (Br.) and has a national capital symbol, but is "Singapore", whereas countries are usually all-caps like "MALAYA". Even states and colonies are usually all-caps... then again, Singapore is a city. Anyway, Singapore gained full internal self-government in 3 June 1959. Meanwhile "CAMEROONS [sic] (Fr. Trust)" puts the globe before 1 Jan 1960.

But over in "FRENCH EQUATORIAL AFRICA" we have subdivisions like "CHAD" (sure) and "UBANGI-SHARI", which was renamed to "CENTRAL AFRICAN REPUBLIC" on 1 Dec 1958 (while not being independent yet.) "UNITED ARAB REPUBLIC" spans Egypt and Syria, so it has to be after Feb 1958.

We seem to have a conflict: independent-ish Singapore in 1959, but Ubangi-Shari in 1958.

OTOH, I might be mis-interpreting what it's trying to say about Singapore, or they might have been lazy about keeping up with changes in French Africa.

Oh, Guinea being independent puts it after 2 Oct 1958. So if we ignore Singapore we're down to a two month period in 1958. Pretty good!

There's "DAHOMEY" within "FRENCH WEST AFRICA" but not the (non-independent) "REPUBLIC OF DAHOMEY" which suggests being before 11 Dec 1958.

Separately, there's just "GERMANY", no FDR and GDR. I'd briefly thought it might be a pre-WWII globe, but then I saw North and South Vietnam and Korea. Also Israel. So, no. Both Germanies at the time insisted they were the one true Germany but I would assume that was true of Korea and Vietnam too.

Edit: I also learned some things. Like HADHRAMAUT where eastern Yemen is now, but part of Saudi Arabia. TRUCIAL OMAN, MUSCAT AND OMAN...

Edit 2: The globe has FR SOM, BR SOM, and SOMALIA. Somalia was a UN Trust Territory between 1950 and 1 July 1960, at which point it joined with British Somalia. No indication of trust status on the globe. BR SOM and SOMALIA seem to have a border but are also the same shade of yellow. But it can't be 1960, because Cameroon...

I'd long relied on Google Earth's ruler tool. I didn't like the hassle of installing it on the VM I'm currently using. So I looked, and found Google Maps has one! Just right-click on a point.

Wow, the Swiss really do vote 3-4 times a year. Last one was Nov 28, and they just had another one, on three initiatives. http://www.swissinfo.ch/eng/swiss_news/Swiss_agree_to_curb_immigration_and_rethink_EU_deal_.html?cid=37877780 discusses one and links to the other two. 50.3% majority to reinstate quotas on EU immigration, rather than a free travel and labor market. 70% rejecting a conservative measure to remove abortion from the list of basic health insurance services; 62% in favor of more money for the train system, http://www.swissinfo.ch/eng/swiss_news/Swiss_railways_could_benefit_from_fresh_cash_boost.html?cid=37579820 (older article)

Somewhat randomly, the abortion article includes an interactive graphic with abortion policies around the world. http://www.swissinfo.ch/eng/swiss_news/Abortions_to_remain_covered_by_health_insurance.html?cid=37889424
Clever examining of the HTML finds the source link: https://mapsengine.google.com/map/embed?mid=zPsccFWjDz38.klFLKBjCbzdk

Huh, 2 of the 3 initiatives passed. That's unusually high, I think. I also note part of the Swiss method at work in the railway case:

"The cabinet has characterised the upcoming vote on the fund as “historic”. It is a counter-proposal to an initiative that was successfully spearheaded by the Transport and Environment Association and other organisations and would have modified the constitution.

Those backing the initiative were sufficiently satisfied with the government counter-proposal to withdraw their initiative last summer. It has also convinced the cantons and the country’s two largest automobile associations – the Automobile Club of Switzerland and the Touring Club Switzerland... Because the federal constitution has to be adapted if the proposal is accepted at the ballot box, a majority of voters as well as a majority of cantons must vote in favour."

100,000 voters can propose an initiative; government can propose a counter. I knew that, but this is me seeing it in action. Didn't know the original proposal could be withdrawn. And it's still an initiative, despite coming from the government. Seems like this could have been a law, but Swiss voters can't initiate federal law.

Okay, someone at Swissinfo likes Google maps. I found this older article on the new marijuana law, and it has another world map

I thought maybe they were finding them, but the text in this one credits Swissinfo. OTOH, the abortion one doesn't, and it looks different, that might be found.

Which prompted me to learn that Tibet's population is a whopping 3 million people. (Well, the province anyway; some claim 6 million Tibetans over all, elsewhere.) Xinjiang, the giant province to the north, has 25 million. Qinghai and Ningxia to the north east have about 6 million each. Most of China's population really is in the eastern half or even third, where the rain and greenstuff are. Also puts "Free Tibet" in a new perspective for me. Bhutan is under 800,000! OTOH, Nepal is 27 million. Its capital Kathmandu has 700,000, comparable to most of Bhutan.

I've never considered myself an expert on geography, whatever that means, but part of my childhood was my father throwing out unexpected geographical facts or questions. Like, "does the Panama canal go east to west?" (Nope: Atlantic to Pacific is NW to SE, given how Panama twists. Not that the canal is that much of a straight line, as I just learned.) The relative latitudes of the US and Europe are fairly well known (Newfoundland, Paris) I never did buy his claim that Nevada was west of California, since some points of Nevada are west of many points in CA (including LA); my counter was that every point in Nevada has a point in CA to its west.

South American being east of North America is my favorite personal discovery. Came about when a friend in Berkeley said she was flying to Chile via Miami, which seemed bizarre, until I looked and traced down the latitude lines. Miami barely clips Ecuador. Boston is basically due north of Chile. Which isn't how the flights go... right, because I've never flown that direct, it's always been Dallas or Toronto or Miami connecting. I also like my Portland-Minneapolis-Lyon latitude line, and the realization that Seattle is thereby north of Minneapolis. Doesn't feel like it!

OTOH, I somehow grew up thinking Toronto was basically north of Chicago, Ottawa a bit NE from there, and Quebec some vague distance off to the east. Later I thought Toronto was near Detroit, as opposed to being near Buffalo like it is.

There's a miscellaneious transit and antique map store near me, and I popped in today and walked out with a tiny -- size of a grapefruit -- globe for $15. "Antique style" where antique might mean 1950. It's fairly up to date, though it doesn't have South Sudan. (I'd bet good money not all my readers know there's an independent South Sudan. I wouldn't be surprised if Eritrea had missed a few brain cells as well.) It's tiny and missing a lot of detail compared to a normal sized globe -- no Quebec City, though it does have La Serena to my surprise, but no Valparaiso which seems rather arbitrary -- but it's big enough to spin around and find countries and marvel at geographical facts, those I'm familiar with and those I know but don't feel and those I didn't know at all, without taking up a lot of space.

Tonight I wondered if there were flights over the North Pole as great circle routes would indicate. (yes) I've recently seen a graphic on the true size of Africa, but there's an extra visceral impact of paying attention on a globe, free from any projection distortions. Harder to tell exactly how many large countries fit into Africa, but very clear that the US and China do, while India is like half or 2/3 of non-Russian Europe.

It's also pretty impressive to look at India, or eastern (old Han) China, and realize that about 1/5 of the world population lives and always has lived in each of those fairly small areas. I'm also realizing that India isn't that much bigger than Kazakhstan, Iran, or Saudi Arabia, or old Sudan, to list relatively nearby countries with much smaller populations.

I'd always thought of Australia as pretty isolated, and I guess it kind of is, but on the globe it look right next door to Indonesia. I measured it on Google Earth, and it's 200 km to Indonesian New Guinea, about 700 km from Darwin to Indonesian Timor. Pretty far on a rowboat, but a few days on a rather slow ship. Of course, most Indonesians live a lot further away.

Then a double weirdness. "Oh, there's Fiji and Samoa, way to the south Pacific." "Hey, someone in LA had debated Caribbean vs. Fiji vacation plans, saying Fiji wasn't that much farther. That's nuts." "Wait, right, he lives in LA, not Boston. And if I measure it out... huh, Fiji's maybe less than twice the distance to Barbados." "Huh, from west Cuba to Barbados is like 1600 miles."

Google Earth is awesome, BTW, and definitely better for measuring things than a globe that doesn't even indicate the scale, and it tries to cope with projection problems. But I still like playing with a real globe more, partly because Google's not so good at keeping useful labels around while zoomed out, and you have to switch scales to move around easily.

Greenland looks *so tiny*. That's in the "I know it, but seeing it is always a shock" category. A lifetime of Mercator projections really messes you up. South America is rather large, mostly due to Brazil. Antarctica, pretty small compared to Africa or South America, though menacing Australia for its lunch money.

Of course my babbling about this probably doesn't have a 1/10th the impact it would if we were looking at a globe together. I could spend the effort linking to maps, but that would seem to miss the point.

Nice not having to fend off a preschooler who wants to just spin the globe a lot, as was the case for the last globe I played with. :)
