Digital Terrain Model of the Czech Republic of the 4th generation (DMR 4G)

The Digital Terrain Model of the Czech Republic of the 4th generation (DMR 4G) represents a picture of natural or by human activity modified terrain surface in digital form as heights of discrete points in a regular grid (5 x 5 m) with coordinates X,Y,H, where H means the altitude in the Baltic Vertical Datum - After Adjustment with total standard error of 0.3 m of height in the bare terrain and 1 m in forested terrain. The model is based on the data acquired by altimetry airborne laser scanning of the Czech Republic territory between years 2009 and 2013. DMR4G is established to analyse terrain situation at regional scale and character, e.g. for extensive transport and water management projects planning, natural phenomena modelling etc.

Other information: EPSG code 5514 S-JTSK / Krovak East North is an equivalent to the existing ESRI code 102067. The projection keeps the mathematic so called "east-north" orientation of coordinate axis where the X axis has positive values eastwards and Y axis northwards. This projection is suitable for exploitation in GIS applications. The projection is related to the Greenwich Prime Meridian (contrary to the EPSG 5221 S-JTSK (Ferro) / Krovak East North where the Prime Meridian is Ferro).
