OceanWise licence EK001 - 20140401

OceanWise's Raster Charts XL are derived from raster-based hydrographic charts obtained under licence from the UK, and other, Hydrographic Offices where land and other non-marine features have been removed. This provides familiarity for users who work with nautical charts and has the advantage of being able to combine it with any land mapping, or aerial imagery, of your choice.

Marine Themes Digital Elevation Model (DEM) of the Seabed generated from single beam echo sounder (SBES) and multi beam echo sounder (MBES), where available, and Electronic Navigational Chart (ENC) or GEBCO derived data where not. The 1 arc second resolution data set is divided and supplied as 0.5 degree x 0.5 degree tiles. The 6 arc second resolution data set is divided and supplied as 2.0 degree x 2.0 degree tiles. The coastline used in the DEM is based on the High Water Line extracted the largest scale Electronic Navigational Chart (ENC) available for a given area, edited to be contiguous and attributed by height extracted from the Vertical Offshore Reference Frame (VORF).

This layer shows the anchorages that have been designated and where a harbour / port authority  may request a vessel to anchor. A vessel may also anchor anywhere as directed by a harbour / port authority when within their jurisdiction.

For the main ports, Marine Scotland has confirmed the data with the relevant harbour / port authority. This dataset contains licenced data from OceanWise.

The Ministry of Defence uses Scotland's coasts and seas. The coasts are mainly used for training and locating bases. The seas, while also used for training, are important for test and evaluation activities as well as surveillance and monitoring of potential threats, and for combating these threats. This layer displays the areas of Scottish seas which are actively in use by the MOD. The dataset shows only those areas within Scottish waters and is derived from data licensed from OceanWise, corroborated by the UKHO PEXA web application.
