INSPIRE theme Orthoimagery (OI)

The INSPIRE Orthoimagery data are harmonised according to INSPIRE implementing rules. The dataset contains data from 2024 and 2025. The source dataset is the Orthophoto of the Czech Republic (Ortofoto ČR). The raster image has a ground sample distance of 0.125 m. Positional accuracy is characterised by a mean positional error of approximately 0.20 m. In accordance with the INSPIRE Orthoimagery data specification, the source data have been transformed into the ETRS89-TM33N coordinate reference system. The data are provided in JP2 (JPEG 2000) format. The distribution unit is a 2 × 2 km square.

Abstract: The INSPIRE Orthoimagery data are harmonised according to INSPIRE implementing rules. The dataset contains data from 2024 and 2025. The source dataset is the Orthophoto of the Czech Republic (Ortofoto ČR). The raster image has a ground sample distance of 0.125 m. Positional accuracy is characterised by a mean positional error of approximately 0.20 m. In accordance with the INSPIRE Orthoimagery data specification, the source data have been transformed into the ETRS89-TM33N coordinate reference system. The data are provided in JP2 (JPEG 2000) format. The distribution unit is a 2 × 2 km square.
Purpose: This dataset of the Orthophoto of the Czech Republic therefore has the unified design with other data created for this INSPIRE theme in frame of whole Europe.
