Prof. Eka Djunarsjah’s work centres on maritime boundary delimitation and marine cadastre. He applies these to sea boundary determination, coastal and maritime spatial planning, and the management of marine resources. His recent research also covers satellite-derived bathymetry, tidal prediction, the IHO S-100 marine data standard, flood and coastal hazard modelling, and community-focused projects for fishers and coastal villages.
