The HPD Limits and Boundaries Module offers the world-renowned CARIS LOTS Limits and Boundaries tools within the HPD Source Editor. This functionality is enabled via an optional license setup. It supports law of the sea related work such as the maintenance of the territorial sea baseline model and the geodetic calculation of maritime limits and boundaries within a Database environment. These tools benefit from and are complemented by the latest CARIS technology available in the HPD suite. Because it is part of a seamless database application, this add-in removes file-based data duplications and facilitates the maintenance of law of the sea data.
