The U.S. Geological Survey is conducting a market survey for potential contractors to provide GIS, modeling, and statistical analysis services. This is a sources sought notice to gauge interest and capability from eligible firms; it is not a formal solicitation. The work is intended to support federal, state, and local partners. The associated NAICS code is 513210 with a $47 million small business size standard. Participation is voluntary and any costs for responding are the contractor's responsibility.
