Archive Orthophoto of the Czech Republic

Archive Orthophoto of the Czech Republic, black and white. Acquired since 1998 to 2001. The pixel size is 50 cm. Archival orthophoto of the Czech Republic, colour. Orthophotos acquired since 2002 (test), reguralry since 2003 (one third of the territory) and since 2012 (half of the territory).Up to 2008 the colour Orthophoto was created with the pixel size 0.5m and since 2009 orthophotos already have a unified pixel size of 0.25m. Since 2016 up to 2020 orthophotos had a unified pixel size of 0.20m. As of 2021, the pixel size is 0.125 m. In addition, since 2010, imaging is done with a digital camera, which has greatly contributed to the increase in product quality.The file data is provided in TIFF format and supplemented with TFW files for S-JTSK and ETRS89-TM33N coordinate systems.

Abstract: Archive Orthophoto of the Czech Republic, black and white. Acquired since 1998 to 2001. The pixel size is 50 cm. Archival orthophoto of the Czech Republic, colour. Orthophotos acquired since 2002 (test), reguralry since 2003 (one third of the territory) and since 2012 (half of the territory).Up to 2008 the colour Orthophoto was created with the pixel size 0.5m and since 2009 orthophotos already have a unified pixel size of 0.25m. Since 2016 up to 2020 orthophotos had a unified pixel size of 0.20m. As of 2021, the pixel size is 0.125 m.

Purpose: Archive orthophotos of the CR serve as an information source for the history of the CR territory state on the date of respective acquisition.

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).

Data origin
Data origin information: Production of orthophotos of the Czech Republic from original aerial survey photos. Photographing was performed from 1998 to 2001 (black and white photographic material), from 2002 to 2009, including a color photographic material. Since 2010, uses an electronic record of raster images in bands BW-PANCHRO, R, G, B, NIR, from which they are created or colored images can be created and the images black and white or in false colors (color infrared).
