Land Productivity Dynamics Product of Small Island Developing States (30 meters Resolution)

The production is based on Landsat-8 and MODIS series remote sensing image data, combined with gap-filling and SG filtering algorithm, and spatio-temporal filtering optimization algorithm to obtain high-quality annual 30m NDVI dataset from 2000 to 2023. Based on the NDVI dataset, the 30-meter land productivity dynamics product of Small Island Developing States was produced by using the FAO-WOCAT land productivity dynamics calculation method.This product is the land productivity dynamics product for Small Island Developing States in three phases: 2000-2015, 2004-2019, and 2008-2023. It covers Small Island Developing States with a spatial resolution of 30 meters. Pixel values 1 to 5 respectively represent the declining, early signs of decline, stable but stressed, stable and not stressed, and increasing land productivity dynamics.
