    "description": "The MCA manages a multi-million pound budget to systematically survey the waters around the U.K. This programme is known as the Civil Hydrography Programme. \r\n \r\n Under the programme, commercial contracts are let regularly to ensure accurate hydrographic information is gathered for updating the nations nautical charts and publications. The Maritime and Coastguard Agency work in close cooperation with the United Kingdom Hydrographic Office who assist them in discharging the United Kingdoms national hydrographic obligations under the International Convention for Safety of Life at Sea.\r\n \r\n Survey areas are prioritised using a risk analysis methodology. The Civil Hydrography Programme does not cover waters within port authority limits.\r\n \r\n The data included in this file details hydrographic survey extents for contracts which were commissioned under the Civil Hydrography Programme by the MCA.\r\n \r\n Polygon areas represent actual extents of survey data gathered.",
