dKart Navigator system can work with the CM93/3 vector electronic charts developed by the C-Map company. C-Map's world-wide chart collection is a de-facto a standard for commercial applications in navigation all over the world.

The structure of the CM93/3 layout vector electronic charts data is the sheer equivalent of the S-57 ver. 3 (3.1) data but possess no official status. The CM93/3 charts are distributed on a CD-ROMs and updated on a regular basis (More).

The S-57 standard developed by the International Hydrographic Organization (IHO) is designed for the official cartographic data exchange between different hydrographic organizations. The transition from the S-57 standard version 2 (DX90) to the later S-57 standard edition 3 (3.1) is being implemented at present.  

In accordance with the requirements made for electronic cartographic navigational systems to be certified as ECDIS, dKart Navigator system can use completely the data of both S-57 editions.

ARCS (Admiralty Raster Chart Service) is a raster electronic chats layout of UK Hydrographic Service. The ARCS electronic charts are available practically for any region of the world ocean at present. The raster electronic charts are simple in production and are worked up to conventional paper ones to the most extent. The raster charts’ main deficiency is the lack of objects database. It makes impossible a navigation situation automatic analyses.

This function is designed for selection of a chart image color palette, most acceptable visual perception according to lightning conditions. For instance, you can select special “night” palettes for a chart handling at night. These palettes ensure a distinct navigation under the reduced light conditions.
