The Wetland Map Validation for Ukraine

This paper considers the topical issue of using data from a drone with a very high spatial resolution to solve the problems of validation of individual classes on land cover maps obtained at the national level with a 10-meter spatial resolution. In particular, this study validated the land cover map for the territory of Ukraine for 2020 and conducted a comparative analysis of orthophoto data with open Sentinel-2 satellite data, as well as validated some wetland locations from the classification map for Ukraine. Comparative analysis showed that orthophotoplane data have a correlation from 0.3 to 0.7 depending on the drone survey parameters with the Sentinel-2 satellite, and large wetlands on data with 10-meter spatial resolution are identified with an overall accuracy of 90%, but for more accurate details of wetlands contours correct will be the use of orthophotos data.
