Distance to coastline—image processing. (1) From a mosaic of two LANDSAT images (15 meters spatial resolution) Guadalcanal main island is extracted; (2) A new image of the same spatial resolution is created with a rasterization of Guadalcanal’s surface area; (3) A filter is created to extract the contour of the island to be able to calculate the distance of each pixel of this image to the contour; (4) A multiplication of each pixel distance value by 0 for the sea pixels or by 1 for Guadalcanal island pixel to allow a better display of the distance to the coast for each pixel of the island
