Dynamic chart adjustment using marine data

A system for presenting marine data, the system comprising:

• at least one sonar transducer associated with a watercraft, wherein the at least one sonar transducer is configured to emit one or more sonar beams into an underwater environment of a body of water in a direction relative to the watercraft;
• a display;
• one or more processors;
• memory including computer program code configured to, when executed, cause the one or more processors to:
• cause, on the display, presentation of a chart including a representation of at least a portion of the body of water, wherein the chart is presented at a first zoom level;
• cause the one or more sonar transducers to emit the one or more sonar beams into the underwater environment;
• receive sonar return data corresponding to sonar returns received by the at least one sonar transducer;
• determine a distance of the one or more sonar beams, wherein the distance corresponds to a sonar range;
• generate a sonar image corresponding to the sonar return data, wherein the sonar image is presented based on a sonar image scale;
• cause, on the display, presentation of the sonar image on the chart relative to a representation of the watercraft on the chart;
• determine, based on the determined distance, a second zoom level of the chart that corresponds to the sonar image scale such that a length of the sonar image extending from the representation of the watercraft or a length of a representation of the distance extending from the representation of the watercraft covers at least 25% of a length of the chart;
• and
• adjust, based on the determination of the second zoom level, presentation of the chart to the second zoom level that corresponds to the sonar range, such that the sonar range covers at least 25% of the chart, wherein the second zoom level is different than the first zoom level.

• receive sonar return data corresponding to sonar returns received by the at least one sonar transducer;
• generate a sonar image corresponding to the sonar return data, wherein the sonar image comprise a sonar image scale;
• determine a distance corresponding to a maximum presented sonar range within the sonar image scale;
• cause on the display, presentation of the sonar image adjacent the chart;
• determine, based on the determined distance corresponding to the maximum presented sonar range, a second chart scale of the chart that corresponds to the sonar image scale such that a length of the sonar image would cover at least 25% of a length of the chart if overlayed on the chart to dimension;
• and
• adjust, in an instance in which the length of the sonar image, if overlayed on the chart, does not cover at least 25% of the length of the chart, presentation of the chart to the second chart scale, wherein the second chart scale is different than the first chart scale.

• cause, on the display, presentation of a heading line relative to a representation of the watercraft, wherein the heading line comprises scale lines corresponding to the first zoom level;

• and
• adjust, based on the determination of the second zoom level, presentation of the scale lines to the second zoom level such that the second zoom level corresponds to the sonar image scale.
