Zoom in on a blue dot and click to see and download the map for free. When you and others record and upload sonar logs of boat trips in those gray-scale areas, you can replace the less-detailed gray-shaded contours with highly detailed blue-shaded C-MAP Genesis contours, and eventually create an entirely new, and amazingly accurate, map for the water body.Įach blue dot indicates a waterbody mapped with C-MAP Genesis. The gray-scaled contours on Social Map charts appear in areas where the C-MAP Insight basemap has not yet been improved by custom contour mapping with C-MAP Genesis. The blue-shaded areas are those that have been mapped with C-MAP Genesis, so those areas will appear in very high detail (usually with 2- to 5-foot contours, although shallower waterbodies can appear with 1-foot contours, and very deep waterbodies might display with 10-foot contours). On many waterbodies that are partially mapped, you will see both blue-shaded depth areas and gray-shaded depth areas. On the Social Map, online at waterbodies that are completely mapped feature charts with entirely blue-shaded depth areas - darker blue denotes deeper water lighter blue indicates shallower water. Some waterbodies have already been completely mapped by community-minded anglers, others are partially mapped, and some remain a blank slate, ready to be mapped.
