WebLogis, Map Gallery, and Loudoun Mapping Applications
Loudoun County has two online mapping services. WebLogis is an interactive mapping system that accesses the county’s Geographic Information System (GIS) directly. Data layers are updated on differing schedules, though addresses, parcels, and streets are updated daily. The mapped information on the site reflects the information on the GIS from the previous day. As of October 10, 2017, a Pictometry imagery tool is available on the site! For help in using WebLogis, visit the help page.

The Loudoun County map gallery contains all maps published by the county. Maps in the gallery are also available as large scale, printed maps. If you have any questions about the map gallery, please read the FAQs.

Loudoun Mapping Applications are stand-alone applications provided by Loudoun County to meet a variety of community inquiries. Whether you need to locate your local sheriff station or find the latest land development applications, this quick link provides easy access to several map related web sites created by Loudoun County.

The first phase of GeoHub is now available.  It offers applications focused on transportation, Envision Loudoun, and recreation.  Additional applications pertaining to community, public safety, and economic development will be added to GeoHub in the coming months.
