ALEXANDRIA, Va.—ERDC Topographic Engineering Center’s (TEC) Doug Caldwell and researchers from George Mason University completed the study, “Crowdsourcing Geospatial Data: A report on the emerging phenomena of crowdsourced and user-generated geospatial data,” which examines crowdsourcing and geospatial data quality.
The study is aimed at geospatial users who are considering using Crowdsourced Geospatial Data (CGD) or adopting CGD approaches for geospatial data collection.
The study introduces the concept of crowdsourcing, compares CGD production with traditional national mapping agency production, highlights significant crowdsourcing applications, examines data quality issues, and offers a series of approaches for evaluating crowdsourced geospatial data. The report is available from the Defense Technical Information Center at http://www.dtic.mil/dtic/tr/fulltext/u2/a576607.pdf.
