Social Map is a free, global, online collection of inland and coastal C-MAP Genesis charts generated by the Lowrance, Simrad Yachting and B&G communities of fishing, cruising, and sailing enthusiasts. Anyone with an account can download free Social Map charts to an SD card for use on the water in a compatible chartplotter.
To make the best maps, only (non-private) trips that meet the high standards of the GIS professionals on our Quality Control team are included in Social Map.
Blue water drops represent locations where sonar data has been voluntarily contributed by C-MAP Genesis users. Sonar data marked “private” is not aggregated in Social Map. Users with an Edge account can also see bottom hardness of the voluntarily contributed data. Click on the "Composition" icon found in the upper right corner in the Social Map page. Gray-shaded contours in Social Map represent legacy base-map data.
