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. Survey areas are prioritised using a risk analysis methodology. The Civil Hydrography Programme does not cover waters within port authority limits. The data included in this file details hydrographic survey extents for contracts which were commissioned under the Civil Hydrography Programme by the MCA. Polygon areas represent actual extents of survey data gathered.

Version 2009 2 Dataset reprojected to WGS 1984 UTM Zone 30N Version 2009 1 The polygons represent the extents of areas where survey data was obtained by the hydrographic survey contractor which undertook the survey. Polygons were created from analysing the bathymetric product delivered by the contractor. This process was undertaken by the UKHO. MCA staff then created and populated an attribute table with the following attributes: HI Name: Hydrographic Instruction name. A Hydrographic Instruction (HI) is the MCA job-specific specification which is given to the contractor and which defines the area-specific requirements for a particular hydrographic survey. The HI supplements a more generic contract specification. HI Number: A unique HI reference number which is used internally by the MCA and UK Hydrographic Office (UKHO). HI numbers are assigned by the UKHO. Contract: The MCA contract under which this work was undertaken Contractor: The MCA contractor which undertook the work Standard: The overall standard to which the survey data was gathered Start Date: The day which the contractor started offshore operations on the polygon area. End Date: The day which the contractor completed offshore operations on the polygon area. FY Comissi: The financial year (April 1st to March 31st) in which the survey work was first comissioned. Status: Flag to indicate whether the survey has been completed (Surveyed) or is planned for the future (Planned) Area KmSq: The total area of the polygon (in WGS UTM -3 deg)
