Abstract: Various implementations described herein are directed to a device configured to use motion sensing for controlling a display. The device may include a motion sensing module configured to track orientation of a user on a watercraft and determine a direction of a cast executed by the user based on the tracked orientation of the user. The device may include a display module configured to display one or more sonar images based on the determined direction of the cast executed by the user.

Abstract: A method of processing geo-statistical data includes piloting a watercraft with a monitoring system on a water body, taking measurements of a depth of the water body and the position of the watercraft using the monitoring system, and aligning the depth measurements with the position measurements. The method also includes creating a contour map from the depth and position measurements, creating a polygon on the contour map, and analyzing at least one of the depth and position measurements within the polygon.

Abstract: An apparatus for synchronizing cursor events may include a processor. The processor may be configured to receive an indication of a cursor event of a cursor presented within and associated with a sourcing window of a user interface that also includes a sourced window, wherein the cursor of the sourcing window indicates a geographical location within the geographical area presented by the sourcing window. Additionally, the processor may be configured to communicate information reflecting the cursor event to the sourced window. The processor may further be configured to subject the cursor of the sourced window to the cursor event reflected by the information to thereby synchronize a cursor event of the cursor of the sourced window with the cursor event of the cursor of the sourcing window, wherein the cursor of the sourced window indicates the geographical location indicated by the cursor of the sourcing window.
