Remote Sensing

Elevation Derivatives for National Applications (EDNA) is a seamless, nationwide, multi-layered three-dimensional (3D) hydrologic database derived from a version of the National Elevation Dataset.

The Coastal National Elevation Database (CoNED) Project - topobathymetric digital elevation models (TBDEMs) are merged renderings of both topography (land elevation) and bathymetry (water depth) to provide seamless elevation products for select coastal regions in the United States (2011-present).

Spaceborne Imaging radar data (C-band and L-band) from two Space Shuttle missions (1994).

The SPOT Historical archive holdings were received from the SPOT IMAGE Corporation in 1999. The French space agency, Centre National d'Etudes Spatiales (CNES), owns and operates the SPOT satellite system and worldwide commercial operations are anchored by private companies (i.e., SPOT IMAGE Corp. of the United States and other distributors around the world).

SPOT Controlled Image Base is an orthorectified product derived from panchromatic images with a 10-meter ground sample distance. Coverage is limited to portions of the United States, Europe, Middle East, Southeast Asia, North and South Korea, Central America, western Russia, and other smaller areas around the world. (1986-1993)
