sheer amount of information we've

10
00:00:22,230 --> 00:00:20,000
collected all across the world since

50 years of las vegas expanding may be

fairly simple to notice but we can also

observe short-term changes

much water was used by each farm field

data to manage irrigation and increase

of coastal waters

35
00:01:22,630 --> 00:01:20,560
the increased precision and data sent

36
00:01:24,149 --> 00:01:22,640

distinctions in the levels of light

00:01:57,510 --> 00:01:55,280
scientists have used landsat to track

00:02:01,429 --> 00:01:57,520
shrinking glaciers for decades and

54
00:02:05,270 --> 00:02:03,350
the glaciers in the himalayas are a key

meltwater collects in large lakes at

59

high altitudes and poses a flooding risk

to downstream villages

61
00:02:19,830 --> 00:02:16,800
landsat data is essential to monitor the

growth of these lakes

63
00:02:23,910 --> 00:02:21,840
because of their location glaciers are

00:02:25,990 --> 00:02:23,920
not easy to study in person but

65
00:02:28,309 --> 00:02:26,000
landsat's view from space allows us to

66
00:02:30,150 --> 00:02:28,319
study glaciers all around the globe

67
00:02:31,830 --> 00:02:30,160
landsat 9's improvements will make it

68
00:02:32,869 --> 00:02:31,840
easier to see features on the glacier

the glacier is moving

how it has changed over the past decades
