Polygons were created from analysing the bathymetric product delivered by the contractor. This process was undertaken by Natural England (NE). NE 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. This field has not been completed by NE as this relates to MCA filing systems 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 NE contract under which this work was undertaken Contractor - The NE contractor which undertook the work Standard - The overall standard to which the survey data was gathered. This has not been completed by NE. 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 30N)
