Na Łotwie ortofotomapy są przygotowywane w łotewskim systemie współrzędnych LKS-92 TM zgodnie z podziałem arkuszy map TKS-93 (arkusz mapy w skali 1:10000 odpowiada 5 x 5 km w terenie). Ortofotomapy są przygotowywane dla całego terytorium Łotwy w skali 1:10 000, a dla poszczególnych obszarów – miast i gęsto zaludnionych terenów – w skali 1:2000 lub 1:1000.
Zbiór danych RGB ma 3 pasma: czerwone, zielone i niebieskie.
