Orthophoto of the Czech Republic

Colour apparently seamless orthophoto of the Czech Republic in 8 bit colour scale. Raster image pixel of the Orthophoto CR displays approximately 0.20 m of the territory in the medial terrain plane. The positional accuracy characterized by standard error in coordinates in flat terrain is 0.25 m, in ragged terrain 0.5 m. Orthophoto CR is distributed in graphic raster formats JPG in export units displaying 2.5 x 2 km of terrain in division into map sheets of the State Map 1 : 5,000.

Abstract: Colour apparently seamless orthophoto of the Czech Republic in 8 bit colour scale. Raster image pixel of the Orthophoto CR displays approximately 0.20 m of the territory in the medial terrain plane. The positional accuracy characterized by standard error in coordinates in flat terrain is 0.25 m, in ragged terrain 0.5 m. Orthophoto CR is distributed in graphic raster formats JPG in export units displaying 2.5 x 2 km of terrain in division into map sheets of the State Map 1 : 5,000.
Purpose: The Orthophoto of the Czech Republic is exploited in the branch of Ministry of Agriculture as a background for evaluation of fundamental production units in the LPIS system, in the branches of ČÚZK and Ministry of Defence it serves also as a fundamental background for topographic data database update and consequently for update of state map series. The Orthophoto of the Czech Republic is provided to many other users and above all it is intended for state administration bodies and organisations and local governments where is exploited for planning and project preparation, in nature protection, risk management and many others.

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. Since 2012 one half of the state territory is carried out to digitally raster electronic record in the BW-PANCHRO, R, G, B, NIR, they are made of colored images, or can be made in black and white or images in false colors (color infrared).
