Pourquoi ce Petit Village Apparaît Toujours sur les Cartes
Imaginez cette petite ville australienne qui se retrouve soudainement sous les feux de la rampe en raison de quelque chose appelé le "Phénomène Baltimore". En gros, il s'agit d'un bug étrange où les cartographes ont continué à copier une erreur sur une vieille carte, marquant cet endroit aléatoire comme "Baltimore" au lieu de son véritable nom. Et paf, comme ça, cette petite ville devient une sensation mondiale, célèbre non pas pour son propre charme mais pour cette incroyable confusion. Les locaux doivent probablement trouver cela amusant, voyant les touristes arriver, se grattant la tête, se demandant où sont tous les crab cakes. Animation créée par Sympa.

00:00An intriguing cartography phenomenon is the so-called Baltimore phenomenon, which is a result of cartographic generalization.
00:10This phenomenon occurs when a city or another object is placed on a map without sufficient space,
00:17while smaller cities simply appear there because there is enough space for them.
00:23It owes its name to the city of Baltimore, in Maryland, often absent from maps due to the proximity of larger cities such as Washington, District of Columbia.
00:33On the other hand, smaller and less well-known cities, such as Alice Springs in Australia, sometimes appear on the same maps only because there is space available.
00:44On this scale, Alice Springs, with its some 25,000 inhabitants, is indicated, while the big city of Guangzhou and its more than 14 million is curiously absent.
00:57This phenomenon is particularly frequent on automated cartography sites, but it does not occur at all levels of enlargement.
01:05On popular platforms such as Google Maps and others similar, Baltimore only appears from certain zoom levels, such as 5th, 6th or 7th.
01:15Cartographers can adjust their maps to ensure that they are useful and effectively transmit spatial information,
01:22finding the right balance between the presentation of important details and the maintenance of a clear and readable map.
01:28The best maps are those that show the essential elements explicitly while accurately representing the world.
01:36But Alice Springs is not the only anomaly on the map of Australia.
01:40Examine the time zone map.
01:43This section of 10 and a half hours seems a little off, doesn't it?
01:48In reality, Australia is officially divided into three standard time zones, the Western, Central and Eastern.
01:55The normal time in the centre of Australia corresponds to the Greenwich Meridian, plus 9.30, the different states and territories deciding to apply or not to the summer time.
02:06The Australian insular territories and the stations in Antarctica add to the complexity of the time zones.
02:12However, the Australian time zones are generally easy to understand.
02:17In addition to the official time zones, there is an official hybrid time zone called the Western Australian Standard Time Zone.
02:26This time zone is located between the Western time zone, UTC plus 8, and the Central time zone, UTC plus 9.30,
02:35positioning itself at UTC plus 8.45, which is a unique difference of 15 minutes.
02:41The Western Australian Standard Time Zone is observed only in a small region located at the extreme southeast of Western Australia, along the Ayer Highway.
02:52The area covered by this time zone includes localities such as Cockleby Dee, Madura, Moondrabilia, Eucla and Border Village.
03:01Only a few hundred people live in this region, which facilitates the agreement on an unconventional time zone.
03:08Despite the absence of official approval, the Western Australian Standard Time Zone continues to be observed due to the significant gap between the Western and Central time zones,
03:20particularly during the summer, when Southern Australia observes the summer time, while Western Australia does not.
03:28The use of this unique time zone can often lead to confusion, even among locals.
03:33For example, the Eucla police work according to the Perth time zone, which sometimes causes delays during events such as gatherings.
03:42Residents have indicated that in the past, Eucla followed its own official time zone, which simplified things well before aligning with the Perth time zone.
03:52They also face some confusion, because their geographical location in Southern Australia does not allow the adoption of the summer time.
04:00The history of the Western Australian Standard Time Zone dates back to the establishment of a telegraphic station in Eucla in 1877.
04:09Although the exact origins of this time zone are uncertain, it is assumed that it was adopted to avoid errors at the telegraphic station located at the border between Western Australia and Southern Australia.
04:22The UTC plus 9.45 historically corresponds in Australia to the summer time zone of the Western Centre.
04:31Some road links along the Ayr Highway in Southern Australia and Western Australia adopted the UTC plus 9.45 during the summer months, when Southern Australia observed the summer time.
04:45Although not officially recognized by the authorities, the limits of this time zone are clearly defined and often represented on road maps.
04:54Five Australian towns, including Border Village, Kaigouna, Eucla, Madura and Moondrabila, previously observed the UTC plus 9.45 time zone.
05:06But currently, these zones operate on UTC plus 8.45 due to the lack of change of summer time in Western Australia.
05:13Australia is not the only country to have atypical time zones.
05:19China, with a population of about 1.5 billion people and being the third largest country in the world, operates on a single time zone known as Beijing Time or China's Normal Time.
05:35This unique time zone covers almost five different geographical areas of the country.
05:42Thus, in some Chinese cities, the sun can rise as late as at 10 a.m. and lunches can be taken after 2 p.m., or even after 4 p.m. for those who are not in a hurry.
05:55Since 1991, the UTC is no longer observed in China.
06:00However, the Xinjiang region, located in the west of the country, observes the Xinjiang time zone, which is two hours late compared to China's standard time, and is considered an unofficial time zone.
06:14Nepal also has a unique time zone, since it operates at Nepal's time all year round, without resorting to summer time.
06:23What is special is its UTC shift of 5.45, which means that Nepalese clocks are 5 hours and 45 minutes ahead of the universal time coordinated.
06:37There is only a 15-minute difference with neighboring India, where their standards were identical until Nepal established its own time zone in 1956.
06:48Let's now look at the map of Europe.
06:54Great Britain, Portugal and Spain are located at about the same latitude.
07:01However, there is a one-hour gap between Portugal and the United Kingdom compared to Spain.
07:07Why is that?
07:08In the 1940s, Spain adopted the German time zone due to a certain ideological proximity.
07:17Over time, despite the end of the dictatorship, Spain remained in this time zone, thus being one hour behind its neighbors of the same latitude.
07:28But like many other countries, Spain applies the summer time well.
07:32Greenland, if it were independent, would be ranked as the 12th largest country in the world, but it currently belongs to Denmark.
07:41The country has three different time zones.
07:44Most of it is three hours behind Greenwich's average time.
07:48Except for the city of Ithokkortormiit on the east coast, which is only one hour behind.
07:53The airbase of Thule in the northwest operates at GMT-4.
07:57While the small population of Denmark-Chavne observes the hour of the Meridian.
08:04The summer time has been set to offer more light in the evening after work.
08:09This can help save energy by reducing the need for lighting and heating.
08:14Proposed for the first time by Benjamin Franklin in 1784 to align the waking hours with the daylight and save energy,
08:22it was implemented in Port Arthur, Ontario, in 1906.
08:27Since then, many countries have adopted this practice, although some regions near the equator or at high latitudes
08:34have chosen not to follow it due to minimal variations in the hours of sunrise.
08:39In the United States, the summer time is observed almost everywhere.
08:44Except in Hawaii and Arizona.
08:47The extremely hot climate of Arizona makes the changing of hours not relevant to save daylight.
08:53Residents prefer to do their activities during the fresh hours of the morning rather than sweating in the evening.
08:59However, the Navajo Nation, an autonomous Native American territory, follows the same hour-changing calendar as the rest of the country.
09:07Although it extends over three states, Arizona, New Mexico and Utah,
09:12the Navajo Nation keeps a uniform hour on these lands.
09:17As for Hawaii, its tropical position leads to minimal variations in the duration of sunrise throughout the year.
09:24If Hawaii adopted the UTC-9 during the summer time, the sun would rise around 7 am in June.
09:31Indeed, most of the islands are located west of the time zone Hawaii-Aleutienne
09:37and should theoretically be in the time zone following the west.
09:41Note that in the past, their Hawaiian standard was based on a different length than today.
