Enterprise GIS is the implementation of GIS infrastructure, processes and tools at scale within the context of an organization, shaped by the prevailing information technology patterns of the day. It can be framed as an infrastructure enabling a set of capabilities, and a process for establishing and maintaining that infrastructure. Enterprise GIS facilitates the storage, sharing and dissemination of geospatial information products (data, maps, apps) within an organization and beyond. Enterprise GIS is integrated into, and shaped by the business processes, culture and context of an organization. Enterprise GIS implementations require general-purpose IT knowledge in the areas of performance tuning, information security, maintenance, interoperability, and data governance. The specific enabling technologies of Enterprise GIS will change with time, but currently the prevailing pattern is a multi-tiered services-oriented architecture supporting delivery of GIS capabilities on the web, democratizing access to and use of geospatial information products.
While federal agencies establish national geospatial policies and produce foundational data, state and regional governments are the critical hubs where these national frameworks are adapted to meet regional needs and local priorities. State-level geospatial coordination is essential for aggregating data from local governments, providing a unified operational picture for statewide challenges, and ensuring that local data can integrate with national programs. The National States Geographic Information Council (NSGIC) provides a unified voice for states at the national level, while State Geographic Information Officers (GIOs) lead coordination efforts within their respective states. This entry examines the role of state and regional bodies in the U.S. geospatial ecosystem, their primary functions, common challenges, and their indispensable role in bridging national policies with local implementation. These state-level activities are conducted within the broader framework of national policies and programs, as detailed in the entry on National Organizations and Programs (DC-07-022).
