DOM as hillshade

DOM represents the earth's surface including all stable and visible landscape elements such as soil, natural cover, woods and all sorts of constructive works.

DOM is not updated and the data will not be adjusted.


  • In open terrain: ±0.5 m 1σ
  • In terrain with vegetation: ±1.5 m 1σ


Types of Models

The DOM isdelivered in two types:

The type "raw" is a cloud of vector points (x,y,z) with a density of about 1 point per 2 m2. It's the basis model and can serve for highly specialised terrain investigation.

formates of delivery: 

  • ASCII X,Y,Z single space

The type "GRID 2 m" has been interpolated from the raw model and is a 2 m grid. In the areas above 2000 m this grid is being suplemented by DHM25 Level 2. Due to easier handling this type can be directly used in geographic information systems and for orthorectification of aerial phtos or satellite images.

Formats of delivery:

  • ASCII X,Y,Z single space

Coordinate System:

  • LV03 LN02
