Accuracy makes all the difference.

Lowrance HDS 12

According to one published report, the maps available in the “vast majority of electronic cartography” is based on historical data from governmental agencies – data often 50 years old or more!

To get “1-foot contours” for maps of such lakes, companies run a computer program to estimate depths between government-drawn contours lines and then just fill in the blanks. That’s why you often see structure on your sonar screen where your map shows nothing.

C-MAP Genesis allows you to record your own sonar data, upload that to our cloud-based database and start seeing detail that isn’t available anywhere else.

The world's best community-sourced maps.

Built on a base layer of existing contour data, Social Map is updated continuously, in near real-time, with sonar data contributed by the C-MAP Genesis community – giving users the most accurate charts available.

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. Anyone with an account can download FREE Social Map charts to an SD card for use on the water in a compatible chartplotter.
