OpenCPN is a free software (GPLv2) project to create a concise chart plotter and navigation software, for use underway or as a planning tool. OpenCPN is developed by a team of active sailors using real world conditions for program testing and refinement. This plugin is designed to allow users to place objects/items on the OpenCPN interface and have these georeferenced. This allows the objects/items to move with the chart and have a definined Latitude and Longitude. There are two basic types of object/item that can be used: points and paths. Points are very similar to Waypoints and mark locations on the chart. Paths joint two or more points together and draw a line between them. Currently these Points exist: Boundary Point, Text Point, Electronic Brearing Line (EBL) Point, Dead Reckoning (DR) Point. These Points are used to construct special types of Paths: Boundary, Electronic Bearing Line (EBL) and Dead Reckoning (DR).
