摘要：The use of common standards and interoperable systems and techniques for digital geospatial data and information collection, archive, integration, and open sharing on a national scope is taking root in more and more nations. Pundits with a global perspective recognized that these same benefits can be realized across international and intercontinental boundaries as well. The Global Spatial Data Infrastructure (GSDI) took first form in 1995 with the small gathering of government organizations, industry, and academic luminaries in Bonn, Germany to exchange ideas on how to evolve and promote the ideas of SDI on a regional and a global basis. The Eighth GSDI meeting was just held in Cairo, Egypt in collaboration with the FIG Working Week. Between 900 and 1000 attendees represented 88 nations. The association currently has over 25 organizational members and roughly as many individual members. The goal of the organisation is to encourage and promote SDI awareness and capacity building globally. This is done primarily by working with partners to seek and distribute resources to assist fledgling SDI development primarily (but not exclusively) in emerging nations. The five major goals include: continue to develop awareness and exchanges; promote standards- based data access/discovery/use through the internet; encourage capacity building; conduct SDI development research; and engage partners to leverage resources for all of the above. One of the programs includes the development of three regional newsletters distributed electronically focusing on SDI and GIS conferences, workshops and training, and the URLs for organizations that are supporting SDI development. A "small grant" program was also instituted to help stimulate the building of SDI components within organizations in nations with emerging SDI programs. Major grants form ESRI and Intergraph are key to stimulating SDI development nationally. A portal has been made available for searching for data globally along with web services and roughly 288 clearinghouses are available and pinged hourly to determine which are operational or not and why. The GSDI also distributes the GSDI "Cookbook" providing instructions to policy level, management level and operational people responsible for building SDIs
