Fact Sheet 2011–3103

Volunteer Map Data Collection at the USGS

By Eric B. Wolf, Barbara S. Poore, Holly K. Caro, and Greg D. Matthews

Abstract

Since 1994, citizen volunteers have helped the U.S. Geological Survey improve its topographic maps. Through the Earth Science Corps program, citizens were able to "adopt a quad" and collect new information and update existing map features. Until its conclusion in 2001, as many as 30 volunteers annotated paper maps which were incorporated in to the USGS topographic-map revision process.
