Defence Gridded Elevation Data
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
