3rd production cycle 2023-2025
Third production cycle (2023 - 2025) of the Orthophotomosaic of Slovakia began in 2023, when western part (cca 17 000km2) was taken and orthophotomosaic is available for download from 30.4.2024. In 2024, central part (cca 17 000km2) was taken and orthophotomosaic is available for download from 30.6.2025. In 2025, eastern part (cca 17 000km2) was taken and orthophotomosaic will be available for download form 30.6.2026.

Parameters:
GSD (Ground Sampling Distance): 15 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 = 3490 MS
Accuracy (western part):
Root mean square error:
RMSExy = 0,17 m
CE95 (Circular error 95%):
CE95 = 1,7308 x RMSExy = 0,29 m
Accuracy (central part):
Root mean square error:
RMSExy = 0,18 m
CE95 (Circular error 95%):
CE95 = 1,7308 x RMSExy = 0,31 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.
