The special charts from Hydrographica has a unique amount of detail which makes navigation possible in areas that are otherwise not accessible. The special charts cover many difficult-to-navigate waters in the Stockholm, S:Anna and Blekinge archipelagos as well as Koster and Hallands väderö.

Tridentnav Systems now offers Hydrographica's special charts in vector form in the navigation program Tridentnav ECS, as a complement to the S-57 chart data from the Swedish Maritime Administration. The Hydrographica charts give a significant improvement in the accuracy of the chart image for the areas covered by the special charts.
