Bridging the Gap between Land and Marine Environments

With climate change, rising sea levels pressing harder year on year and the need to manage our resources more carefully in this dynamic environment, the inability to integrate land and marine base information is an increasing problem in many countries. The absence of a seamless spatial data framework prevents the execution of standard practice of locating and referencing spatial data across the land-marine interface where so much pressure and development is taking place. There is a growing and urgent need to create a seamless SDI model that bridges the gap between the terrestrial and marine environments, creating a spatially enabled land-sea interface to more effectively meet sustainable development objectives. This article discusses drivers for integrating land and marine environments and proposes a seamless SDI model as an abstract level SDI and its associated components. This is followed by issues and challenges that must be overcome in developing an overarching architecture for a seamless SDI that allows access to and interoperability of data from marine, coastal and terrestrial environments.
