The INSPIRE Elevation TIN data are harmonised according to INSPIRE Implementing Rules. 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 – 5th generation (DMR 5G). For compliance with the data specification data were transformed to coordinate reference system ETRS89-TM33N and heigh reference system EVRS. Data are provided in GML format, version 3.2.1. Export units are defined by tiles 2 x 2 km. The file consists mainly from coordinates of descrete points, that are supplemented by addtition information.
The source data set is the Digital Terrain Model of the Czech Republic – 5th generation (DMR 5G), that is based on the data acquired by 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. 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.
