The set of Geographic Information Systems (GIS) Script Tools for Renewable Energy zoning enables stakeholders to customize the zoning analysis by changing parameters and input files to meet the specific needs of each stakeholder or to best represent the country context. It allows the calculation of zone attributes and the outputs can be used to update the zone ranking tool. It also allows the user to create a site suitability map, which is effectively a spatially-explicit way to estimate resource potential, using any exclusion and renewable resource inputs and can be used to create project opportunity areas.
