Distribution of Large Scale Orthophotos (LSO) D. Heraklion

Distribution of large scale orthophotos (LSO) of EKCHA S.A. The orthophotographs were produced from aerial photographs of the period 03/2007-09/2008 and cover the entire country. The size of the pixel on the ground is 0.50 m, they have dimensions on the ground 4 000 m x 3 000 m, without perimeter coating, and follow the distribution of EGSA87 scale 1:5000. The type of files is TIFF (with the corresponding georeference file — tfw) and have a 24-bit radiometric resolution. The geometric accuracy of LSO orthophotos is RMSEx ≤ 1.00 m, RMSEy ≤ 1.00m, RMSExy ≤ 1.41m. The absolute accuracy of the product is ≤ 2.44m, for a 95 % confidence level. The orthophotos were granted by the OKHE to the PSDATM, under the terms of the Creative Commons Creative Commons Attribution 3.0 Greece license.
