We realize that the quality of a marine charts design affects its reader’s ability to extract information, learn from the map, and navigate in confidence. Cartography has been developed in an effort to portray the world accurately and effectively convey information to the map reader. A legend explains the pictorial language of the map known as its symbology. The title indicates the region the map portrays; the map image portrays the area and so on. Although every map element serves some purpose, convention only dictates inclusion of some elements while others are considered optional. A menu of map elements includes the neatline (border), compass rose or north arrow, overview map, scale bar, projection, and information about the map sources, accuracy and publication. Boaters Marine Supply offers Marine Charts from Delorme, Garmin, Lowrance, Magellan, Maptech, Navionics, and Raymarine and more. We have the latest and most up to date cartography and marine charts available anywhere at affordable prices. We have over 2100 Marine Charts for just about any area of the world you wish to navigate.
