Spatial Data Infrastructure

A Spatial Data Infrastructure (SDI) provides a framework of standards, policies, data, procedures and technology to support the effective coordination and dissemination of spatial information. The GPC Group has developed powerful methods for the planning, design and implementation of SDI in different cultural and disciplinary contexts.
 
Geographic Information Systems (GIS) have become an indispensable tool for managing and using spatial information at the local, regional, national and global levels. Many organizations need the same information, but in most countries there is no structure for the effective coordination and sharing of these data. A Spatial Data Infrastructure (SDI) provides a framework of standards, policies, data, procedures and technology to support the effective coordination and dissemination of spatial information. Extensive national SDI programs are now underway in North America, Europe, Australia and elsewhere, and a Global SDI Association (GSDI) has been active for several years. These existing programs have established important groundwork, but most countries with developing and emerging economies are not prepared to commit the level of investment required to follow these models at a similar rate of development, and many have special political, economic and legal contexts that require a unique approach. In addition, different disciplinary communities that have not traditionally been involved in collectively addressing spatial data issues are emerging in various scientific and other contexts. For most national or disciplinary purposes, SDI development is a step-by-step, incremental process that must acknowledge the special circumstances of each context. The GPC Group has developed methods for the planning, design and implementation of SDI in different cultural and disciplinary contexts.
