Orthophoto Map Sheets
Orthophoto maps are individual orthophoto sheets "cut" from the orthophotomosaic using regular grid. Estonia is covered by 2074 orthophoto map tiles of 5 by 5 km. Projection, tiling and coding of sheets coincide with the 1:10 000 scale Estonian Basic Map. GSD is 20-25 cm. Low altitude flights above rural areas have 10-16 cm GSD. Low altitude flights will take place each year (in springtime) at least above towns like Tallinn, Tartu and Pärnu.
