NASA Worldview Tutorial

Worldview is a visualization tool that allows the user to browse satellite imagery products from LANCE (Land Atmosphere Near real-time Capability for EOS) centered on your school or observation site by referencing your registered latitude and longitude. Worldview provides near-real time (NRT) data and imagery, which means you can compare data within three hours of your observation.

Please click the information icon for more details. The information icon is a circle with the letter “i“ inside and is located in the top right corner of your Worldview window.

Some items to explore with this tool:

  • Icons Across the top navigation bar to the right of the screen:
    • Permalink: Provides a link to copy and paste in order to share the image.
    • Choose a Projection: “Full Globe”, as well as Antarctic and Arctic projections are available.
    • Take a Snap Shot: Allows you to capture a screen shot of the image you have on the computer. When clicked, this button will allow you to define the area you would like the screen shot of, as well at the resolution and format of the image.
    • Information: Provides overview, acknowledgments, disclaimer, and support information.

  • My Layers, located on the left side of the screen provide Base Layer and Overlay options. You may turn off the Base Layers and Overlay options by clicking the small “x” in the top right corner of the respective boxes. You can also click the icon in the My Layers title line to Show Product Listing.
    • Show Product Listing: Allows the user to choose an “Interest Area” different from the current image you are viewing. For example, “Air Quality”. After choosing an interest area you are prompted to choose your Base Layer and Overlay.
    • Base Layers; grey box: Provides the information of the layer you are currently viewing. For example, “Correlated Reflectance (True Color); Terra/MODIS”.
    • Overlay; grey box: Provides the information of the current overlays on the image you are viewing. For example, “National Boundaries; SEDAC/ National Boundaries”.

  • Zoom In and Out by utilizing the plus and minus buttons at the right of the screen. These buttons work similar to the zoom in and out on Google Earth and are helpful when locating an exact position on the globe.
