DESCRIZIONE
Various implementations directed to a depth display (400) using sonar data are provided. In one implementation, a marine electronics device may include a sonar signal processor and a memory having a plurality of program instructions which, when executed by the sonar signal processor, cause the processor to receive sonar data from a transducer array disposed on a vessel, where the sonar data corresponds to a marine environment proximate to the vessel. The memory may also have program instructions which, when executed by the sonar signal processor, cause the processor to generate point cloud data based on the received sonar data. The memory may further have program instructions which, when executed by the sonar signal processor, cause the processor to generate a depth display (400) based on the point cloud data, where the depth display includes a depth line (440) representing an underwater floor of the marine environment.
