The Geographic Objects Initiative defined platform-independent and implementation-neutral interface models of specific geographic services or component objects. The specific Geographic Object interfaces modeled relate to mapping processes (render or query, for example) or an input or output of those processes (a coordinate or a map, for example). Creating high-level interface models to given Geographic Objects in the Unified Modeling Language (UML) allows developers to take advantage of the valuable components on any development platform or distributed computing platform. GO-1 sponsors and supporters, including government organizations in the United States, seek these models because they allow straightforward reuse of existing capabilities for new projects, an important goal of software systems development.
