GIS Worlds: Creating Spatial Data Infrastructures, a new book from ESRI Press, provides an overview of the developments in spatial data infrastructures (SDIs) over the last 10 to 15 years. Author Ian Masser examines the development of SDIs for sharing geographic data in local, state, regional, national, and international agencies.
GIS Worlds is structured around four themes: SDI diffusion, evolution, implementation, and institution building within a hierarchy of SDIs. Within these themes, Masser discusses key issues in SDI development including government policy options and strategies for SDI implementation. The book also explores the contributions SDIs are making in countries throughout the world.
“The importance of SDI has grown as our capacity to handle large quantities of spatial information has increased exponentially over the last 20 years as a result of developments in GIS technology, at the same time, our power to access this information has been transformed by the development of the Internet and the World Wide Web.” said Masser.
He further says that SDIs have considerable potential for improving the delivery of basic services such as health care and utilities, facilitating public planning and management activities, and promoting sustainable development.
