TerraColor® Product Specifications

The TerraColor global coverage encompasses approximately 9,500 individual Landsat scenes divided into roughly 1266 5x6 degree TerraColor tiles (each a seamless mosaic of several Landsat scenes). The TerraColor mosaic tiles are offered in the Geographic (Latitude Longitude) map projection and the WGS84 datum with units of decimal degrees. The pixel resolution (GSD) is 0.5 arc-seconds (0.0001388 decimal degrees or ~15 meters). TerraColor can be purchased off-the-shelf in JPEG2000 and ECW compressed image formats in 5x6 degree tiles for ease of use and delivery, and also in uncompressed 1x1 degree GeoTIFF tiles.

5x6 degree tiles in JPEG2000 and ECW compressed formats:

  • Tile size: 5.05 degrees north-south and 6.05 degrees east-west
  • Overlap between tiles: 0.05 degrees.
  • File size: Variable due to compression, but < 2GB each

1x1 degree tiles in uncompressed GeoTIFF format:

  • Tile size: 1.001388 degrees north-south and 1.001388 degrees east-west
  • Overlap between tiles: 0.001388 degrees (10 pixels)
  • File size: 149MB

Complete mosaics of large countries and continents are also available as single image files in ECW or JPEG2000 formats. Other map projections such as UTM and Mercator can be provided upon request for an additional charge.
