00:00:01,050 --> 00:00:05,050
NASA’s fleet of Earth-observing spacecraft
2
00:00:05,050 --> 00:00:09,050
provides a unique view of our home planet...and from your computer, you can
3
00:00:09,050 --> 00:00:13,050
view and share that dynamic planet as it is right now.
4
00:00:13,050 --> 00:00:17,050
Using NASA’s Worldview app, you can watch tropical storms develop
5
00:00:17,050 --> 00:00:21,050
over the Pacific Ocean; track the movement of icebergs after they
6
00:00:21,050 --> 00:00:25,050
calve from glaciers and ice shelves; see wildfires
7
00:00:25,050 --> 00:00:29,050
spread and grow as they burn vegetation in their path.
8
00:00:29,050 --> 00:00:33,050
And pan and zoom to your region of the world to not only see what it looks like today,
9
00:00:33,050 --> 00:00:37,000
but to investigate changes over time.
10
00:00:37,000 --> 00:00:41,000
With Worldview’s map interface, capture what’s interesting to you
11
00:00:41,000 --> 00:00:45,000
with a snapshot or an animated gif. Start by going to worldview.earthdata.nasa.gov.
12
00:00:45,000 --> 00:00:49,050
13
00:00:49,050 --> 00:00:53,050
When you first open the app, Worldview has a pre-loaded natural
14
00:00:53,050 --> 00:00:57,050
color image – observed by the MODIS instrument onboard NASA’s Terra satellite.
15
00:00:57,050 --> 00:01:01,050
If you’d like to experiment with NASA’s other satellite
16
00:01:01,050 --> 00:01:05,050
views of our home planet, you can click the “Add Layers” button on the left
17
00:01:05,050 --> 00:01:09,050
side of the screen and find different ways to look at Earth.
18
00:01:09,050 --> 00:01:13,050
Once you’ve got your layer selected, pan and zoom into the location you’re
19
00:01:13,050 --> 00:01:17,050
interested in. You can also switch from the traditional geographic view
20
00:01:17,050 --> 00:01:21,050
to a polar view, to take a closer look at the Arctic or Antarctic regions.
21
00:01:21,050 --> 00:01:25,050
Now it’s time to create your gif.
22
00:01:25,050 --> 00:01:29,050
Click the video camera icon on the left side of the timeline along the bottom of the page.
23
00:01:29,050 --> 00:01:33,050
Select the date range you’re interested in.
24
00:01:33,050 --> 00:01:37,050
Worldview automatically sets to 10-day increments, but you can increase
25
00:01:37,050 --> 00:01:41,050
or decrease that timespan, and look at present day or the past.
26
00:01:41,050 --> 00:01:45,050
If you’re looking at the present day, you may see a big
27
00:01:45,050 --> 00:01:49,050
black swath. That’s because the data is so new, it’s still
28
00:01:49,050 --> 00:01:53,050
coming down! Step back a day to get a full image.
29
00:01:53,050 --> 00:01:57,050
Click the "Create Animated GIF" icon on the right side of the
30
00:01:57,050 --> 00:02:01,050
Animation box. Drag and adjust the box to select the region you want,
31
00:02:01,050 --> 00:02:05,050
then click on the “Create GIF” button. There it is!
32
00:02:05,050 --> 00:02:09,050
Worldview has created your gif and you can download it!
33
00:02:09,050 --> 00:02:13,050
Now for the most important step...share it!
34
00:02:13,050 --> 00:02:17,050
35
00:02:17,050 --> 00:02:21,050
36
00:02:21,050 --> 00:02:25,050
