CEFAS24-138 RFQ for satellite data imagery for Blue Belt island nations

Tender description

Request for quotation for satellite data imagery for Blue Belt island nations (Anguilla & Diego Garcia) The Blue Belt programme is the UK Government’s international marine conservation programme. It works closely with UK Overseas Territories to assist them in creating and maintaining healthy and productive marine ecosystems. As part of this programme, the Cefas coastal processes team have been working on two projects in Anguilla and Diego Garcia, to help monitor erosion of the coastline. A large part of this work is helping to improve the understanding of the natural processes that are occurring on the islands through modelling and mapping the historic movement of the coastline. This is with an aim to create a database of historic and present coastal data, which can be used to determine an environmental baseline to advise coastal management decisions in the future. Due to the remote location of these islands and small populations, background environmental data is sparse. Therefore, Cefas require satellite imagery of the islands over a range of dates for each island, in which the shoreline can be extracted to map its historic movement. Requirement: For both islands, Anguilla and Diego Garcia, two sets of high-resolution WorldView Satellite Data are required. Please see the shapefiles (included within the Bidder Pack) for the two islands of the coverage required. The resolution should be less than 1m at a minimum. The satellite imagery must have numerous bands of imagery, ideally 8, but at a minimum include o Red o Green o Blue o Near Infrared o Shortwave Infrared Although not required for shoreline extraction, Cefas will give preference if the supplier is able to provide an option to include a coastal band in addition, as this will open up scope for more in-depth analysis of shallow water should Cefas wish to carry this out. It is Cefas’ preference that all images are pan-sharpened. If this is not possible, please state within your tender submission. Please note that the panchromatic band must be provided alongside those specified above for Cefas to do this work if the supplier cannot. The dates for the satellite data required are the following: Anguilla 7th February 2014 A mosaic of 5th January 2021 and 31st December 2020 Diego Garcia 3rd June 2024 29th January 2011 Reduction of any image overlap between data sets within the Orthomosaic, if possible, would be preferable. If the supplier believes there are alternate dates for the years shown above with better resolution (i.e. less cloud cover, or for other reasons); then these would also be considered. Cefas would request that the supplier communicates this and creates a jpg. image of the alternative date, with reasoning as to why the change of date has occurred. The imagery licence must be a group licence, or allow multiple owners (ie. Cefas and one other body for each country respectively), as a copy of the data will be given to the administrations for which Cefas are working on their behalf. Any recommendations from the supplier on the image settings (such as on pixel values or atmospheric correction) that may help the purpose of this data (shoreline extraction and analysis year on year) will be welcomed. Deliverables: 1. Two Anguilla orthomosaic datasets with full coverage for the following dates: a) 7th February 2014 b) A mosaic of 5th January 2021 and 31st December 2020 To be delivered within 3 weeks of the contract 2. Two Diego Garcia orthomsoaic datasets with full coverage for the following dates: a) 3rd June 2024 b) 29th January 2011 To be delivered within 3 weeks of the contract. Datasets are to be delivered in a suitable file structure (to be discussed at kick off meeting) with a readme file provided and an inventory of the image file names. Datasets would be expected to be sent via a Sharepoint which Cefas will set up. Location for services to be undertaken: At the Supplier’s premises, to be sent to Cefas on a Sharepoint.
