WebbThe Spectral Characteristics Viewer is an interactive tool that can be used to visualize how the bands, or channels, of different satellite sensors measure the intensity of the many wavelengths (colors) of light. This is also known as the relative spectral response (RSR). WebbLandsat 8 measures different ranges of frequencies along the electromagnetic spectrum – a color, although not necessarily a color visible to the human eye. Each range is called a band, and Landsat 8 has 11 bands. Landsat numbers its red, green, and blue sensors as 4, 3, and 2, so when we combine them we get a true-color image such as this one:

Nat) Google Creative Lab Google Earth is an amazing tool that lets ordinary humans—sans wings or jetpack—zoom around the world. And, as you might know if you’ve checked out the new Google Earth, the 3D imagery looks insane. WebbLidar — Light Detection and Ranging — is a remote sensing method used to examine the surface of the Earth. Lidar data collected using NOAA survey aircraft reveals a top-down and side view of Loggerhead Key Lighthouse, Dry Tortugas, Florida. NOAA scientists use lidar-generated products to examine both natural and manmade environments. oil with gold flakes makeup
