Space-time integration has long been the topic of study and speculation
in geography. However, in recent years an entirely new form of space-time
integration has become possible in GIS and GIScience: real-time
space-time integration and interaction. While real-time
spatiotemporal data is now being generated almost ubiquitously, and its
applications in research and commerce are widespread and rapidly accelerating,
the ability to continuously create and interact with fused space-time data in
geography and GIScience is a recent phenomenon, made possible by the invention
and development of real-time interactive (RTI) GPS/GIS technology and
functionality in the late 1980s and early 1990s. This innovation has since
functioned as a core change agent in geography, cartography, GIScience and many
related fields, profoundly realigning traditional relationships and structures,
expanding research horizons, and transforming the ways geographic data is now
collected, mapped, modeled, and used, both in geography and in science and
society more broadly. Real-time space-time interactive functionality remains
today the underlying process generating the current explosion of fused
spatiotemporal data, new geographic research initiatives, and myriad geospatial
applications in governments, businesses, and society. This essay addresses
briefly the development of these real-time space-time functions and
capabilities; their impact on geography, cartography, and GIScience; and some
implications for how discovery and change can occur in geography and GIScience,
and how we might foster continued innovation in these fields.
