This is a work-in-progress adaptation of Digital Earth Australia (DEA) and Digital Earth Africa Coastlines products for the Pacific nations. Please refer to the following for a description of the algorithms on which we based this work:
Bishop-Taylor, R., Nanson, R., Sagar, S., Lymburner, L. (2021). Mapping Australia's dynamic coastline at mean sea level using three decades of Landsat imagery. Remote Sensing of Environment, 267, 112734. Available: https://doi.org/10.1016/j.rse.2021.112734
Bishop-Taylor, R., Sagar, S., Lymburner, L., Alam, I., Sixsmith, J. (2019). Sub-pixel waterline extraction: characterising accuracy and sensitivity to indices and spectra. Remote Sensing, 11 (24):2984. Available: https://doi.org/10.3390/rs11242984
We have adapted the algorithms where necessary to account for differences in the study area and the available input datasets, as well as for performance. A full writeup is in process.
The product is visible on the Digital Earth Pacific map interface.
