20120290200 | MARINE VESSEL NAVIGATION DEVICE, SYSTEM AND METHOD - A marine electronic device such as a chartplotter which includes a display; a location determining component; and a processing system for receiving location data from the location determining component and for causing information to be displayed by display. The processing system causes the display to display information which assists an operator in navigating and ascertaining characteristics of bodies of water, objects on nearby shores, and other vessels. | 11-15-2012 |
20130271301 | MARINE VESSEL DISPLAY SYSTEM - A marine vessel electronic display system includes a first display station that can include a mode selector for permitting selection of a first mode of operation and a processing system causing displays in the first display station to present information related to the selected first mode of operation. The marine vessel electronic display system may include a second display station that can include a mode selector for permitting a user to select a second mode of operation different from the first mode of operation and a processing system causing a display in the second display station to present information related to the selected second mode of operation. | 10-17-2013 |
20150039221 | 3D SONAR DISPLAY WITH SEMI-TRANSPARENT SHADING - 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. | 02-05-2015 |
20150039222 | MARINE NAVIGATION DEVICE WITH IMPROVED CONTOUR LINES - 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 display displays a map representation. The memory element stores digital elevation model data and sonar data for a plurality of bodies of water. The processing element is in communication with the memory element and is configured to select the digital elevation model data or the sonar data from the memory element corresponding to the first body of water, calculate contour line data, the contour line data determining a plurality of contour lines, update the contour line data by selectively removing at least a portion of the contour lines, and generate a map representation including contour lines derived from the updated contour line data, and control the display to visually present the map representation. | 02-05-2015 |
