Description |
| DTM |
|
|
Digital terrain model.
-- Description --
EXAMPLE Buildings, bridges or vegetation do not form part of a DTM.
NOTE 1 For DTM surfaces describing the floor of water bodies (e.g. the sea-floor), the water bodies are not considered as part of the Earth's bare surface. Hence, they are excluded from the DTM.
NOTE 2 For DTM surfaces in which any features placed on the Earth's bare surface have not been totally filtered and excluded, the deviations must be explained in the metadata.

| DSM |
|
|
Digital surface model.
-- Description --
EXAMPLE 1 Vegetation, buildings and bridges are examples of static features.
EXAMPLE 2 Cars, trucks and other dynamic features are examples of temporary phenomena.
NOTE 1 For DSM surfaces describing the floor of water bodies (e.g. the sea-floor) and those features placed on it, the water bodies are not considered as part of the Earth's bare surface. Hence, they are excluded from the DSM.
NOTE 2 For DSM surfaces in which any temporary phenomena have not been totally filtered and excluded, the deviations must be explained in the metadata.
