Monitoring of deforestation and fragmentation in Sarawak, Malaysia between 1990 and 2009 using Landsat and SPOT images

Sarawak is the largest state in Malaysia that covers 37.5% of the total land area. Multitemporal satellite images of Landsat and SPOT were used to examine deforestation and forest fragmentation in Sarawak between 1990 and 2009. Supervised classification with maximum likelihood classifier was used to...
