Funding agencies, research programs, and organizations involved in the implementation of research need to know the potential worldwide impact and applicability of their efforts and investments. The extrapolation domain analysis method (EDA) was developed to produce information about the location, areas, and population potentially influenced by research outputs. This working paper presents detailed steps how to implement an EDA. For a particular research project, it starts with establishing a baseline assessment of the project, and proceeds through data collection, preparation, and similarity modeling concluding with reporting and validation. The guide is designed for users with intermediate knowledge of GIS and Bayesian statistics for a smooth and easy implementation of the method. It also requires the participation of the members of the research project for proper identification of key variables to be used in the process.
