BlueChart cartography is Garmin's exclusive marine cartography. It complements Garmin's new line of handheld mapping products and marine chartplotters.

This line of cartography products is designed to provide interactive viewing of detailed nautical chart data, thereby providing navigators with innovative object-oriented cartography. These detailed electronic nautical charts look just like paper charts when displayed on your Garmin® chartplotter. Features include shading between depth contours, spot soundings, navaids, port plans, wrecks, obstructions, inter-tidal zones, and more. BlueChart offers much larger coverage areas for half the price, meaning a great value for mariners.
