00:00:00.050 --> 00:00:04.090
NASA’s fleet of Earth-observing spacecraft provides

2
00:00:04.090 --> 00:00:08.190
a unique view of our home planet...and from your computer,

3
00:00:08.190 --> 00:00:12.300
you can view and share that dynamic planet as it is “right now.”

4
00:00:12.300 --> 00:00:16.360
Using NASA’s Worldview app you can watch tropical storms

5
00:00:16.360 --> 00:00:20.450
develop over the Pacific Ocean; track the movement of icebergs after they

6
00:00:20.450 --> 00:00:24.610
calve from glaciers and ice shelves; see wildfires spread and grow

7
00:00:24.610 --> 00:00:28.750
grow as they burn vegetation in their path.

8
00:00:28.750 --> 00:00:32.940
And pan and zoom to your region of the world to not only see what it looks like today, but to

9
00:00:32.940 --> 00:00:37.030
investigate changes over time. With Worldview’s map interface,

10
00:00:37.030 --> 00:00:41.170
capture what’s interesting to you with a snapshot or an animated gif.

11
00:00:41.170 --> 00:00:45.340
Start by going to worldview.earthdata.nasa.gov.

12
00:00:45.340 --> 00:00:49.520
When you first open the app, Worldview

13
00:00:49.520 --> 00:00:53.730
has a pre-loaded natural color image – observed by the MODIS instrument onboard

14
00:00:53.730 --> 00:00:57.930
NASA’s Terra satellite. If you’d like to experiment with NASA’s

15
00:00:57.930 --> 00:01:02.130
other satellite views of our home planet, you can click the “Add Layers” button

16
00:01:02.130 --> 00:01:06.330
button on the left side of the screen and find different ways to look at Earth.

17
00:01:06.330 --> 00:01:10.520
Once you’ve got your layer selected,

18
00:01:10.520 --> 00:01:14.720
pan and zoom into the location you’re interested in.

19
00:01:14.720 --> 00:01:18.920
You can also switch from the traditional geographic view

20
00:01:18.920 --> 00:01:23.140
to a polar view, to take a closer look at the Arctic or Antarctic regions.

21
00:01:23.140 --> 00:01:27.330
Now it’s time to create your gif. Click the video camera icon

22
00:01:27.330 --> 00:01:31.640
on the left side of the timeline along the bottom of the page.

23
00:01:31.640 --> 00:01:35.920
Select the date range you’re interested in. Worldview automatically sets

24
00:01:35.920 --> 00:01:39.950
to 10-day increments, but you can increase or decrease that timespan, and look at

25
00:01:39.950 --> 00:01:44.160
present day or the past. If you’re looking at the present day, you may

26
00:01:44.160 --> 00:01:48.400
see a big black swath. That’s because the data is so new,

27
00:01:48.400 --> 00:01:52.650
it’s still coming down! Step back a day to get a full image.

28
00:01:52.650 --> 00:01:56.860
Click the "Create Animated GIF" icon on the right

29
00:01:56.860 --> 00:02:01.100
side of the Animation box. Drag and adjust the box to select the region you want,

30
00:02:01.100 --> 00:02:05.280
then click the orange arrow in the middle. There it is!

31
00:02:05.280 --> 00:02:09.410
Worldview has created your gif and you can download it! Now for the most important step...

32
00:02:09.410 --> 00:02:13.610
share it! You can post it online with

33
00:02:13.610 --> 00:02:17.810
#NASA4Earth to help NASA, and the rest of us here on our home planet,

34
00:02:17.810 --> 00:02:23.533
celebrate Earth Day.
