Welcome to GeoServer, a popular web service for publishing your geospatial data using industry standards for vector, raster and mapping. This presentation provides a gentle introduction to FOSS4G and we will do our best to say the quiet part out loud: - Demo: We have learned from experience, and will introduce GeoServer using a demo. - Usage: Concepts using both a demo, and diagrams to connect to your data and publish as a spatial service. - Checklist: Preflight check-lists capturing common oversights when deploying GeoServer for the first time. - Value: What role GeoServer plays in your organization and what value the application provides. - Community: How the project is managed, and a discussion of the upcoming activities.
