2nd production cycle 2020-2022
Second Orthophotomosaic of the Slovak republic production cycle (2020 - 2022) was completed in 2023. Territory of Slovakia was divided into three parts – west, central and east (each one about 17,000 km2). Aerial photographs of western part were taken in 2020, the central part in 2021 and the eastern part in 2022.
Technical report: Orthophotomosaic of Slovak Republic 2020-2022 (Slovak only).

Parameters:
GSD (Ground Sampling Distance): 20 cm/pixel
Format: TIFF + TFW
Number of channels: 4 (RGBN, 8-bit)
Coordinate reference system: S-JTSK(JTSK) - EPSG code:5514
Number of map sheets (MS) in 1:5000 scale: territory of western Slovakia = 3418 MS, territory of central Slovakia = 3435 MS, territory of eastern Slovakia = 3422 MS
Accuracy:
Root mean square error:
RMSExy = 0,21 m
CE95 (Circular error 95%):
CE95 = 1,7308 x RMSExy = 0,36 m
CE95 value defines the radius of a circle centred at the specified point on the orthophotomosaic within which the real horizontal position of the point is located with 95% probability. It represents the magnitude of an error which will not be exceeded in 95% of cases.
