How to create a Satellite Time Lapse Animation?

Time Lapse animation created from satellite imagery can give us sight of changes in earth over a period of time. Today we are going to generate a Time lapse animation using the Heroku web app. You can access this web app using this link. A window with a base map and few tools will be appeared.

1-2. From the toolbar, you can choose “Create timelapse”.

3. Then you can navigate to your Area Of Interest either by searching on the search bar in the top left corner of the screen.

4-5. After that, you can define your Area Of Interest, by drawing a rectangle using the drawing tools available on the left side of the screen.

6. Then from the toolbar appeared on the bottom right of the screen,

  • Choose a collection. Landsat TM-ETM-OLI Surface Reflectance, Sentinel-2AB Surface Reflectance and MODIS are the available collections. In this tutorial, I have chosen Sentinel-2AB Surface Reflectance.
  • If required, you can give it a Title. The default Title will be “Timelapse”.
  • Choose a band combination from the RGB dropdown
  • Choose frame per second. Minimum is 1 and Maximum is 30
  • Choose Start and End Years and Months
  • Options are available for cloud mask and Normalized Difference Index
  • Finally, click on the Create Time laps button
  • The time-lapse will be added to the screen.

7. You can download the time-lapse file by clicking on Click here to download time laps link.

Some of the Time lapse animations that we have created using Heroku web app can be seen below.
