Il database è stato preparato utilizzando i dati satellitari Landsat dell'anno 2000.
Più di 1000 scene Landsat ottenute dal USGS Earth Resources
Observation and Science Center (EROS) sono state classificate utilizzando tecniche
ibride di classificazione digitale delle immagini supervisionata e non supervisionata. Questo
database è la prima e più completa valutazione delle mangrovie del mondo
(Giri et al., 2011).
Il finanziamento parziale di questa ricerca è stato fornito dalla NASA.
Il database delle mangrovie viene utilizzato per identificare le aree prioritarie
per la conservazione delle mangrovie, studiare il ruolo delle foreste di mangrovie
nel salvare vite e proprietà da disastri naturali (ad es. tsunami),
nel calcolo delle emissioni di carbonio e nella conservazione della biodiversità. L'USGS EROS utilizza i dati per studiare l'impatto dell'innalzamento del livello del mare sugli ecosistemi di mangrovie. Il database funge da base di riferimento per il monitoraggio
delle mangrovie.
I set di dati Landsat sono dati creati a livello federale
e pertanto sono di dominio pubblico e possono essere utilizzati, trasferiti o riprodotti senza limitazioni di copyright.
Il riconoscimento o l'attribuzione dell'USGS come origine dati deve essere fornito
includendo una riga di citazione di testo come nell'esempio mostrato di seguito.
