  1. Bathymetry
    Bathymetry is the study of underwater depth of lake or ocean floors. Bathymetric maps may use a Digital Terrain Model and shading techniques using artificial illumination to illustrate the depths being portrayed.
  2. Geographic Fine Art
    Any image based on geography that is suitable for fine art or décor purposes, particularly printed as fine art (a.k.a. giclee) prints. Our Satellite Imagery Maps or Satellite Art printed as giclee prints (or on ceramic tile), are good examples for Geographic Fine Art.
  3. Multi-Resolution Land Characteristics
    The Multi-Resolution Land Characteristics (MRLC) Consortium is a group of federal agencies who first joined together in 1993 (MRLC 1992) to purchase Landsat 5 imagery for the conterminous U.S. and to develop a land cover dataset called the National Land Cover Dataset (NLCD 1992). In 1999, a second-generation MRLC consortium was formed to purchase three dates of Landsat 7 imagery for the entire United States (MRLC 2001) and to coordinate the production of a comprehensive land cover database for the nation called the National Land Cover Database (NLCD 2001).
  4. Satellite Imagery Map
    It is a map, created in an appropriate map projection, based on cloud-free, seamless satellite data. An important distinction between a satellite image and a map, is that the map is produced in GIS or mapmaking software, using a particular “projection”. The image in the resulting map is a different shape to the source satellite image. On the other hand, a satellite image is usually presented as seen from the satellite. It is not a map.
