Description
This information describes the data products used to create the Monitoring Mangrove Extent application. Analysis Ready Data (ARD) is contained wholly within Digital Earth Africa's (DE Africa) Sandbox environment. Data required to run the computation is contained within the Sandbox, there is no need to pull data from outside the Sandbox. Across all DE Africa's applications, ARD comes formatted as Cloud Optimised GeoTIFFs with Spatio Temporal Asset Catalog (STAC) metadata.
The Monitoring Mangrove Extent application uses Sentinel-2 ARD and the mangrove mask from the Global Mangrove Watch (GMW) dataset.
Sentinel-2
The Monitoring Mangrove Extent notebook draws upon Sentinel-2 data for a specified area in a time series. DE Africa uses a time-series of Sentinel-2 data from 2017 onwards which has a spatial resolution of up to 10 metres. Since early 2018, Sentinel-2 satellites have been acquiring images over most of the land surface every five days. Digital Earth Africa provides information on the Sentinel-2a and Sentinel-2b imagery dataset used in this analysis.
Global Mangrove Watch Dataset
The Global Mangrove Watch dataset consists of a global baseline map of mangroves for six periods which include 1996, 2007, 2008, 2009, 2015 and 2016. This dataset used ALOS PALSAR and Landsat (optical) data to form a baseline extent of mangroves and has been rasterised and indexed from the UN Environment Program into DE Africa's Open Data Cube. Digital Earth Africa provides information on the Global Mangrove Watch dataset used in this analysis.
This is a component for the application named Monitoring Mangrove Extent in Africa using Digital Earth Africa Data Cube.
