Garmin BlueChart

BlueChart® cartography is Garmin’s exclusive marine charting. It complements Garmin’s 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, including 1-foot HD fishing contours and enhanced Auto Guidance. These detailed electronic nautical charts look just like paper charts when displayed on your Garmin chartplotter.

Descriptive details for features typically found on nautical charts can easily be viewed with a simple key press. Cursor movements over the chart provide descriptions for contour depths, chart number, navaid name, and much more.

BlueChart® g2 HD

BlueChart g2 HD mapping features 1-foot HD fishing charts, smooth layering and seamless integration of map graphics for easy panning, scrolling and zooming.

With rich colours and shading for easy interpretation and clear visibility, this marine charting offers comprehensive IALA navaid symbols and marine services and 1-foot HD fishing contours. A choice of 3D ‘Mariner’s View’ map perspective, or the familiar 2D direct overhead view makes chart reading and orientation easier. BlueChart is styled to match the appearance of paper charts when displayed on a Garmin chartplotter or GPS mapping handheld device. Features include shading between depth contours, spot soundings, navaids, port plans, wrecks, obstructions, intertidal zones, 1-foot HD fishing charts, restricted areas and more. BlueChart cartography is object-oriented, which means you can pan to an object on the map and instantly view information about that point. Additionally, Fishing Charts contain detailed bathymetric data in a 1-foot interval to emphasise bottom contours and depth soundings. These charts also remove navigation information from the map to reduce clutter and give clearer definition to the sea floor, ideal for fishing.
