Launching the Landsat Image Service for SE Idaho’s Big Desert Research

The GIS Center at Idaho State University is excited to introduce the Landsat Image Service Archive, funded by AmericaView. This innovative project provides access to a wealth of multispectral satellite imagery captured by the Landsat program since its launch in 1984. The service allows researchers to stream raster layers of images, facilitating scientific inquiry into the ecological landscape of the Big Desert in Southeast Idaho. With 63 scenes available, this initiative supports research and promotes valuable insights into environmental changes.

Presentation Transcript

  1. LISA and TIM Keith T. Weber, GISP Idaho State University

  2. TIM • The Idaho Map (TIM) • Idaho Spatial Data Infrastructure (ISDI)

  3. LISA • Landsat Image Service Archive • A new project at the GIS Center • Funded by AmericaView • For more information, visit: • http://americaview.org/ • http://idahoview.org/

  4. What is Landsat? • A multispectral imaging satellite • Its takes “pictures” of the earth • The “pictures” (scenes) are taken every 16 days • Each scene contains 7 “bands”, based on color

  5. Bands and Color

  6. Landsat 5 • Has been in operation for nearly 30 years (expected duty cycle was 5-7 years) • Launched in 1984 • Since that time, quite an archive has been established

  7. What’s an Image Service? • First, what is an image? • A digital picture • In GIS, its a raster layer • An image service then… • Is a raster layer that is shared via the web

  8. So it’s a download? • Nope… • Web services are streamed to your computer • You do not download the source file • It’s similar to

  9. Our Landsat Archive • We have acquired numerous scenes dating back to 1984

  10. LISA project focus • The Big Desert of SE Idaho • Path 39, Row 30 • GIS Center currently has 63 scenes

  11. Image Service Prep

  12. Launching the Service

  13. Why? • Provide the research community with data and value-added products to support scientific inquiry • The Big Desert is an important area ecologically • The GIS Center has over 12 years of research focused on the Big Desert

  14. Questions?
