Position of the nadirs (centres of the shots) of the Ortho-littorale v3
Description
Since 2018, a new air flight campaign on a part of the French coast is engaged in order to establish a coverage of orthophotos on the entire Atlantic and Channel - North Sea coast in metropolitan France as well as on the entire linear of that of Guyana. The production of this orthophotography is carried out at the rhythm of the flight campaigns. These may be carried out only under very specific conditions: at low tide during high tide with a water height of less than 1.50 m under anticyclonic conditions (> 1013hPa) established for at least 48 hours.
This layer locates the location of the centre of the photographic photographs (nadirs) taken during this aerial campaign and for which ortho-littorals are available. Currently, it concerns the linear coastline of Guyana. It will be updated as the Ortho-littorale v3 project progresses.
