Overview:

This standard:

  • is an Data Product Specification (DPS) for elevation data products
  • is an implementation profile for gridded elevation data products based on DGIWG's Elevation Surfance Model (ESM) standard

Specifies:

  • content
  • structure
  • multi-level grid system and tiling-scheme
  • delivery
  • encoding formats

Supports:

  • elevation data storage, access, exploitation and exchange
  • a wide range of geospatial resolutions
  • three rule-based standardised encodings (GeoTIFF, GMLJP2 and NSIF)
  • interoperability between implementations of elevation products (and their specifications)
  • military requirements for a uniform, orthogonal grid-based geospatial elevation model
