• Gridded Data – a multi-dimensional array of measure or estimated values associated with specific locations

  • Digital Elevation Models (DEMs) - height values
  • Bathymetry Models - depth values

• Gridded Data Sources

  • NIMA’s Digital Terrain Elevation Data (DTED)
  • NIMA’s Digital Bathymetric Data Base (DBDB)
