What is WEBLOGIS?
WebLOGIS is Loudoun County’s Geographic Information System (GIS)-based mapping tool for the Internet. It was developed in 2001 to provide easy access the county’s mapped information resources. WebLOGIS provides tools to navigate the map of the county, identify features, and search for a parcel or address. It interfaces with the assessment database, and is updated nightly with the most current parcel and address information.
