Committee and team approaches are frequently employed for coordinating participants and users in multi-participant GIS projects. The aim of creating such committees and teams is to ensure that the varied interests of participants are addressed, as participants bring many different interests, application needs, data needs, priorities, organizational issues, and political interests to a common project the GIS. Common models for coordinating participants recognize that participants have three levels of interest in the GIS: policy, technical development, and usage. Different bodies can be established focusing on these different levels of interest: a technical committee focusing on the design and development of the GIS, an management committee providing policy guidance and support and a user`s group.
