Boaties Sharing Mapping data via New App

The collective efforts of the boating public worldwide in contributing information to existing C-Map cartography will be available via mapping data called Genesis.

The collective crowd-sourcing mapping data will be available on the C-Map navigation app this month and across all Lowrance, Simrad and B&G apps powered by C-MAP charts.

The Genesis layer allows all users across the world the ability to see C-MAP’s extensive crowd-sourced database of marine mapping data that has been reviewed and quality controlled by C-MAP engineers before being published to the public as an option to view on the app’s charts.

“The addition of Genesis on the C-MAP App is just another enhancement that allows users to get the best possible mapping information so they can fish better and know more about what lies beneath the waters,” said Max Cecchini, Executive Vice President, C-MAP.

The Genesis layer adds more than 30,000 submissions to C-MAP charts. It can be beneficial for small, inland lakes where government cartography agencies have not reached or have not updated official data for decades. The U.S. and Nordic regions, in particular, have been very active in user-generated mapping data and uploads. However, sonar logs have been submitted from over 80 countries since its inception, providing a significant global footprint.

User uploads to Genesis have logged nearly one million total hours on the water over the past half-decade to supplement official charting data provided by government bathymetric agencies worldwide.

Also added this month to the C-MAP App is a promotional referral program that provides six months of free high-resolution bathymetry to any user worldwide that refers three new users to the C-MAP App or apps from Simrad®, Lowrance® or B&G® that sync with their onboard displays including chart plotters and fishfinders.

To refer friends, share your unique link from the dropdown in the main menu, and choose how you want to share (via Social Media, WhatsApp, text message, etc.). You'll automatically receive your six months of free HRB when three friends install the App.

Download the C-MAP app here for both iOS and Android. Download the Lowrance app here for iOS and Android. Download the Simrad app here for iOS and Android. Download the B&G app here for iOS and Android.
