For the theme Elevation INSPIRE requires data harmonisation according Elevation - Grid Coverace application schema. This dataset of the elevation of the Czech Republic therefore has the unified design with other data created for this INSPIRE theme in frame of whole Europe. Data were derived from the Digital Terrain Model of the Czech Republic – 4th generation (DMR 4G). For compliance with the data specification data were transformed to coordinate reference system ETRS89-TM33N and heigh reference system EVRS. Data are provided in graphic raster format (tiff) with 5 m spatial resolution together with the accompanying information in GML format.
The source data set is the Digital Terrain Model of the Czech Republic – 4th generation (DMR 4G), that is based on the data acquired bby altimetry airborne laser scanning of the Czech Republic territory between years 2009 and 2013. In this model terrain surface is represented by heights of discrete points in a regular grid 5 x 5 m. For compliance with the data specification data were transformed to coordinate reference system ETRS89-TM33N and ETRS89-TM34N and heigh reference system EVRS. Spatial resolution and accuracy were preserved.
