Leta 2005 je bilo kartografiranega samo 15 odstotkov sveta. To upočasnjuje dostavo pomoči po naravni nesreči -- in skriva ekonomski potencial neuporabljene zemlje in neznanih cest. V tem kratkem govoru, Lalitesh Katragadda iz Googla demonstrira Izdelovalca zemljevidov (Map Maker), skupinsko orodje, ki ga ljudje po svetu uporabljajo, da kartografirajo svoj svet.

In 2008, Cyclone Nargis devastated Myanmar.

1000
5000
V letu 2008 je ciklon Nargis opustošil Mjanmar.
00:21
Millions of people were in severe need of help.
1
6000
4000
Milijoni ljudi so nujno potrebovali pomoč.
00:25
The U.N. wanted to rush people and supplies to the area.
2
10000
4000
Združeni narodi so želeli na območje naglo poslati ljudi in zaloge pomoči.
00:29
But there were no maps, no maps of roads,
3
14000
3000
Vendar ni bilo nobenih zemljevidov, nobenih zemljevidov cest,
00:32
no maps showing hospitals, no way for help to reach the cyclone victims.
4
17000
5000
nobenih zemljevidov z označenimi bolnišnicami, nobenega načina za dosego žrtev ciklona.
00:37
When we look at a map of Los Angeles or London,
5
22000
3000
Če pogledamo zemljevid Los Angelesa ali Londona,
00:40
it is hard to believe
6
25000
3000
težko verjamemo,
00:43
that as of 2005, only 15 percent of the world
7
28000
3000
da je do leta 2005 bilo samo 15 odstotkov sveta
00:46
was mapped to a geo-codable level of detail.
8
31000
3000
kartografiranega s stopnjo podrobnosti na nivoju geokod.
00:49
The U.N. ran headfirst into a problem
9
34000
3000
Združeni narodi so zadeli ob težavo,
00:52
that the majority of the world's populous faces:
10
37000
2000
s katero se sooča večina svetovnih gosto naseljenih območij:
00:54
not having detailed maps.
11
39000
2000
manko podrobnih zemljevidov.
00:56
But help was coming.
12
41000
2000
Vendar je pomoč prihajala.
00:58
At Google, 40 volunteers
13
43000
2000
Pri Googlu je 40 prostovoljcev
01:00
used a new software
14
45000
3000
uporabilo novo programsko opremo,
01:03
to map 120,000 kilometers of roads,
15
48000
3000
da je kartografiralo 120.000 kilometrov cest,
01:06
3,000 hospitals, logistics and relief points.
16
51000
3000
3.000 bolnišnic, logističnih točk in točk s pomočjo.
01:09
And it took them four days.
17
54000
2000
Za kar so potrebovali štiri dni.
01:11
The new software they used? Google Mapmaker.
18
56000
3000
Nova programska oprema, ki so jo uporabili? Googlov Izdelovalec zemljevidov.
01:14
Google Mapmaker is a technology that empowers each of us
19
59000
3000
Googlov Izdelovalec zemljevidov je tehnologija, ki vsakemu od nas omogoča,
01:17
to map what we know locally.
20
62000
3000
da kartografira, kar poznamo lokalno.
01:20
People have used this software
21
65000
2000
Ljudje so uporabili ta program
01:22
to map everything from roads to rivers,
22
67000
2000
za kartografiranje vsega od cest do rek,
01:24
from schools to local businesses,
23
69000
3000
od šol do lokalnih podjetij
01:27
and video stores to the corner store.
24
72000
3000
in od videotek do majhnih trgovin.
01:30
Maps matter.
25
75000
2000
Zemljevidi štejejo.
01:32
Nobel Prize nominee Hernando De Soto
26
77000
2000
Nominiranec za Nobelovo nagrado, Hernando De Soto,
01:34
recognized that the key to economic liftoff
27
79000
2000
je ugotovil, da je ključ za ekonomski vzpon
01:36
for most developing countries
28
81000
2000
za večino razvijajočih držav
01:38
is to tap the vast amounts of uncapitalized land.
29
83000
3000
izraba ogromnih količin neizkoriščene zemlje.
01:41
For example, a trillion dollars
30
86000
3000
Na primer, samo v Indiji je za bilijon dolarjev
01:44
of real estate remains uncapitalized in India alone.
31
89000
3000
neizkoriščenih nepremičnin.
01:47
In the last year alone,
32
92000
2000
Samo lani
01:49
thousands of users in 170 countries
33
94000
4000
je tisoče uporabnikov v 170-ih državah
01:53
have mapped millions of pieces of information,
34
98000
3000
kartografiralo milijone koščkov informacij
01:56
and created a map of a level of detail never thought viable.
35
101000
3000
in ustvarilo zemljevid z neverjetno stopnjo podrobnosti.
01:59
And this was made possible by
36
104000
2000
In to so omogočili
02:01
the power of passionate users everywhere.
37
106000
4000
vneti uporabniki od vsepovsod.
02:05
Let's look at some of the maps
38
110000
3000
Poglejmo nekaj zemljevidov,
02:08
being created by users right now.
39
113000
3000
ki jih uporabniki pravkar ustvarjajo.
02:11
So, as we speak, people are mapping the world
40
116000
2000
Torej, v tem trenutku ljudje kartografirajo svet
02:13
in these 170 countries.
41
118000
2000
v teh 170-ih državah.
02:15
You can see Bridget in Africa who just mapped a road in Senegal.
42
120000
6000
Lahko vidite Bridget iz Afrike, ki je pravkar kartografirala cesto v Senegalu.
02:21
And, closer to home, Chalua, an N.G. road in Bangalore.
43
126000
5000
In, bližje domu, Chalua, ozkotirno cesto v Bangaloru.
02:26
This is the result of computational geometry,
44
131000
3000
To je rezultat računske geometrije,
02:29
gesture recognition, and machine learning.
45
134000
3000
prepoznave gibov in strojnega učenja.
02:32
This is a victory of thousands of users,
46
137000
2000
To je zmaga tisočev uporabnikov
02:34
in hundreds of cities,
47
139000
2000
v stotinah mest,
02:36
one user, one edit at a time.
48
141000
2000
en uporabnik, eno urejanje naenkrat.
02:38
This is an invitation to the 70 percent
49
143000
4000
To je povabilo 70-im odstotkom
02:42
of our unmapped planet.
50
147000
2000
našega planeta, ki še niso kartografirani.
02:44
Welcome to the new world.
51
149000
2000
Dobrodošli v novem svetu.
02:46
