TerraColor NextGen Satellite Imagery
TerraColor NextGen is the next generation of our product line using new (2013-2016) satellite imagery. NextGen products are mosaics of multiple pan-sharpened Landsat 8 scenes that have been carefully processed and balanced to provide high quality color and contrast. Recent imagery can be critically important for many applications, and NextGen provides an up-to-date medium resolution base map of several areas. NextGen also provides a perfect complement to high resolution imagery by providing a consistent, regional view of larger areas.
We are actively developing NextGen products and release new areas on a quarterly basis. All NextGen products are released with a uniform blue ocean fill, but ocean shaded relief fill may be requested. (If you need complete global or continental coverage, please refer to our TerraColor Global product.)
TerraColor NextGen is 100% "true color" imagery. This means it is built from Landsat 8's bands 4, 3 and 2 (which image in the red, green and blue wavelengths of light similar to those in which the human eye sees), along with the 15-meter band 8 for pan-sharpening. So the colors look truly natural (as you would see them from an airplane), which is usually desireable and sometimes very important. (Some vendors produce imagery using infrared bands that simulates "natural colors" so the distinction can be significant.) We also produce the imagery with an optimized contrast stretch to maximize information content and make key features easier to distinguish.
TerraColor NextGen products can currently be purchased by 1x1 degree tiles, individual countries, or region bundles. When purchasing a country, the imagery is clipped to the country border with a buffer extending into the neighboring countries to provide a complete view. NextGen imagery is currently available for over 70 countries (and portions of others). These include coverage of all 50 US states, five Canadian provinces, Western Europe, the Middle East, North Africa, Australia, New Zealand, North and South Korea, Japan and Taiwan. Other areas are coming soon (contact us).
