Sonar mapping system
A sonar mapping system that includes a sonar transducer assembly configured for mounting on a watercraft, and a display configured to show a topographical chart of a body of water. The sonar mapping system further includes a processor coupled to the sonar transducer assembly and display. The processor is configured to create the topographical chart in real time, and to update the topographical chart in real time, based on sonar data provided by the sonar transducer assembly. The processor is configured to render the created or updated topographical chart on the display. The sonar mapping system has memory accessible by the processor and configured to store the topographical chart rendered by the processor, and to store the sonar data provided by the sonar transducer assembly. The sonar data includes information indicative of vegetation present on a lakebed, seabed, or riverbed surface, the information being displayed on the topographical chart.
1. A sonar mapping system comprising:
a sonar transducer assembly configured for mounting on a watercraft;
a display configured to show a topographical chart of a body of water;
a processor coupled to the sonar transducer assembly and display, and configured to create the topographical chart in real time, or to update the topographical chart in real time, based on sonar data provided by the sonar transducer assembly, the processor being configured to render the created or updated topographical chart on the display; and
memory accessible by the processor and configured to store the topographical chart rendered by the processor, and to store the sonar data provided by the sonar transducer assembly;
wherein the sonar data includes information indicative of vegetation present on a lakebed, seabed, or riverbed surface, the information being displayed on the topographical chart.
2. The sonar mapping system of claim 1 , wherein the topographical chart includes one or more bathymetric tints indicative of the vegetation.
3. The sonar mapping system of claim 2 , wherein colors of the one or more bathymetric tints are selectable by a user.
4. The sonar mapping system of claim 1 , wherein the processor is configured to estimate topographical data to fill in missing portions of topographical data adjacent the topographical data gathered via the sonar transducer assembly.
5. The sonar mapping system of claim 1 , wherein the topographical chart includes one or more contour lines indicative of a water depth.
6. The sonar mapping system of claim 1 , wherein the topographical chart includes bathymetric tints indicative of a water depth.
7. The sonar mapping system of claim 6 , wherein colors of the bathymetric tints are selectable by a user.
8. The sonar mapping system of claim 1 , wherein the topographical chart includes bathymetric tints indicative of a hardness of the lakebed, riverbed, or seabed surface.
9. The sonar mapping system of claim 8 , wherein colors of the bathymetric tints are selectable by a user.
10. The sonar mapping system of claim 1 , wherein a chart for a body of water is stored in the memory; and
wherein the processor updates topographical or bathymetric data for the chart based on the sonar data provided by the sonar transducer assembly.
11. The sonar mapping system of claim 1 , wherein the processor is configured to generate a 3-D rendering, including the vegetation, based on sonar data collected by the sonar transducer assembly, and wherein the 3-D rendering is shown on the display.
12. The sonar mapping system of claim 11 , wherein a user can save the 3-D rendering in the memory.
13. The sonar mapping system of claim 11 , wherein different features of the 3-D rendering are shown in different colors.
14. The sonar mapping system of claim 13 , wherein colors for the 3-D rendering are selectable by a user of the sonar mapping system.
15. The sonar mapping system of claim 1 , further comprising a connection for a portable memory device, wherein the processor is configured to access portable memory device.
16. The sonar mapping system of claim 1 , wherein the microprocessor is configured to update the topographical chart in real time by overwriting stored topographical data with new topographical data acquired and converted from sonar data in real time.
17. The sonar mapping system of claim 1 , wherein the processor is integrated into the sonar transducer assembly.
18. A sonar mapping system comprising:
a sonar transducer assembly configured for mounting on a watercraft, and configured to provide sonar data for a 360-degree area surrounding the watercraft;
a display configured to show underwater images based on data from the sonar transducer assembly;
a processor coupled to the sonar transducer assembly and to the display, the processor configured to convert sonar data from the sonar transducer assembly into the underwater images rendered on the display, the underwater images including images of vegetation present on a lakebed, seabed, or riverbed surface, wherein the processor is also configured to overlay the underwater images, in real time, onto a previously-stored chart for a body of water, or to create a new chart, in real time, that includes the underwater images; and
memory accessible by the processor, wherein the processor is configured to store, in the memory, the new chart with underwater images or the previously-stored chart with overlaid underwater images.
19. The sonar mapping system of claim 18 , wherein the underwater images are shown on the display as bathymetric tints in which different features of the underwater images are represented by a plurality of colors.
20. The sonar mapping system of claim 19 , wherein the vegetation is represented by at least one of the plurality of colors, and wherein at least one of the plurality of colors is selectable by a user of the sonar mapping system.
