Conduct geographic information system (GIS) program activities, utilizing GIS hardware and software to produce maps, spatial databases and thematic data (such as wetlands, road centerlines, cadastre, and historic sites) in addition to performing simple spatial analyses. Assist in the development of geographic information systems that create, maintain, or leverage geospatial base-map information. Create, adjust, correct, convert and distribute base maps and thematic data. Digitize and maintain spatial databases; document procedures, validate data for accuracy and completeness, complete approved metadata forms and produce maps of the resulting information. Evaluate information and data from outside sources to determine the quality of the data.  Act as a “consultant” to internal customers during their use, development and quality assessment of spatial databases.
