Dave D. Greenlee has served NEON as a member of both the Technical Review Group and Land Use Analysis Package Tiger Team. He specialized in Geographic Information Systems (GIS) for over 35 years. Since 1974, he has worked at the USGS EROS Data Center, focusing on GIS applications and the integration of GIS with Remotely Sensed data. Greenlee has worked to web enable small- to medium-scale data (including elevation, orthoimagery, land cover data) from the USGS Geography Discipline in order to deliver geospatial datasets such as The National Map. More recently he has assisted partners-including NEON, OneMap, and post-Katrina GIS for the Gulf-in designing GIS databases and distributing geospatial data and map services.
