Abstract
A marine navigation device comprises a location determining element, a display, a memory element, and a processing element. The location determining element determines a current geolocation of a marine vessel on a first body of water. The memory element stores sonar data for a plurality of bodies of water. The processing element is in communication with the memory element and is configured to access the sonar data from the memory element corresponding to the first body of water, calculate bottom hardness shading data based on the sonar data, generate a map representation of at least a portion of the first body of water corresponding to the current geolocation, the map representation including shading derived from the calculated bottom hardness shading data, and control the display to visually present the map representation.
