HydroYandex_all_EucDist_log2x100_int - Logarithmized Euclidean distance to water bodies, multiplied by 100. The data of the topographical maps, zoom 14 layer was classified into aquatic and non-aquatic objects. For the data obtained, the logarithmized distance to water features was calculated. Resolution 10 m.
