The Natural Resource and Energy Explorer (NREX) is a Web GIS-based tool that supports pre-planning development considerations by enabling discovery, analysis and assessment of energy, environmental, cultural, socioeconomic and infrastructural assets for user-defined, project-scale areas of interest in the state.

The NREX application is designed to provide access to geographic data and information maintained by state and federal agencies. Its primary audience includes developers, conservationists, consultants, planners, policy makers, and resource managers with interests in assessing potential place-based resource allocations. A secondary audience includes educators and the general public seeking map-based sources of information for Wyoming's natural, cultural and energy resources.
