Digital earth applications in the twenty-first century

In these early years of the twenty-first century, we must look at how the truly cross-cutting information technology supports other innovations, and how it will fundamentally change the information positions of government, private sector and the scientific domain as well as the citizen. In those positions, location will be a prominent linking pin. The classical top-down system architectures of information exchange will be diluted by peer-to-peer and bottom-up channels, forcing us to rethink their designs. We should not only focus on better architectures, but need to attend to a different economy of information exchange, in which the ‘client’ is not only the information sink, but has become an important source as well. The laws of this rising ‘infoconomy’ have yet to be settled on. This special issue on ‘Digital Earth Applications: Technological design and organizational strategies’ brings together a number of papers that shed light on this future information ecosystem in which location-specific information will be exchanged between stakeholders. The introduction presents a framework that combines geoinformation streams and organisations brokering between government, science, private sector and citizens. This novel framework helps us improve the appreciation of those papers
