Overview History of Remote Sensing with Fiji ForestryHistory of Remote Sensing with Fiji Forestry Demands in Remote SensingDemands in Remote Sensing

History GIS and Remote Sensing started in Forestry in 1993 With collaboration for the National Forest Inventory of In line with the assistance of GTZ- GOPA

Forest Type / Function Map

National Forest Inventory

Image Data Source Landsat 7 25m resolution -> 1:50,000 About 30 scenes 2000, 2001, bands available: blue, green, red, near IR, short wave IR Most scene pre-corrected to UTM

LandSat 7 Satellite Image
