Coastal remote sensing research at Northern Territory University (NTU) has been conducted since 1992. The Department and of Lands, Planning and Environment (DLPE) have also been utilising remote sensing technology in aiding management of the coastal region of the Northern Territory. In this time, expertise in the application of remote sensing has been developed with reference to the diverse tropical coastal environments of northern Australia. This is illustrated in the following natural resource management projects undertaken at the NTU and DLPE: 1. Natural resource management in Aboriginal communities using Landsat TM; 2. Mapping threatened marine Turtle feeding grounds, using Landsat TM; 3. Coral reef classification using Landsat TM; 4 .Mapping coastal wetland salt intrusion using AIRSAR and optical data; 5 .Identifying Trochus shell habitat, using Landsat TM; 6 .The Oil Spill Response Atlas (OSRA); and 7. Monitoring the Mary River Wetlands. These studies have identified strengths and limitations inutilising remote sensing technology in tropical coastal environments. Future directions in coastal remote sensing for northern Australia will be explored, particularly regarding the use ofhyperspectral, airborne high-resolution and polarimetric SAR data.
