The methodology being used for the Forewind contract has been developed by HiDef Aerial Surveying Ltd and is based on aerial surveys using digital imaging equipment. The methodology for video survey of waterbirds was developed by HiDef in conjunction with JNCC. Field trials of this system have demonstrated its ability to meet or exceed the performance requirements specified within the BTO report with current method and protocol directives endorsed by all relevant stake holders including JNCC, SNH, CCW, Natural England, Defra, MFA and The Crown Estate. HiDef was contracted to fly surveys focusing on the following areas within Dogger Bank. Zone - April 2010 to Dec 2010 Tranche A - Jan 2011 to Dec 2011 Tranche B - July 2011 to Jun 2012 For each survey month flown the following are produced. - Report (PDF) - Observations (ESRI shapefile and Excel spreadsheet) - Tracks (ESRI shapefile) There will be no limitations when published on the Marine Data Exchange otherRestrictions Data Must be used in accordance to the Marine Data Exchange's Terms of Use: https://www.marinedataexchange.co.uk/content/info/terms-of-use otherRestrictions The Crown Estate +44 020 7851 5000 enquiries@thecrownestate.co.uk custodian HiDef Aerial Surveying Limited +44 (0)1946 814463 enquiries@hidefsurveying.co.uk originator The Crown Estate +44 020 7851 5000 enquiries@thecrownestate.co.uk distributor SSE Renewables renewablesdps@sse.com owner continual Delimited Documents Geographic Information System https://www.marinedataexchange.co.uk/details/TCE-2468/summary A link to the web service or dataset. https://www.marinedataexchange.co.uk A link to the general host site.

High definition video images are taken of the survey area, which is over-flown in a pre-planned series of transects, using GPS to ensure accuracy; transects are selected to provide the degree of area coverage required by the client. The recorded images are stored on heavy duty disk drives. Following the survey, the disk drives are couriered back to the HiDef premises for review and analysis. The survey images are viewed by trained reviewers using high definition viewing screens and a software image management package that allows the reviewer to adjust and control the appearance of the images and so determine which are birds, mammals etc. Reviewers are not required to identify objects, but simply mark the image as requiring further analysis. Images that have been marked as requiring further analysis are passed to specialist ornithologists who have received training in the analysis of high definition video imagery. Images can be managed using software to enhance their appearance and assist the ornithologist in identifying the object down to species level.
