What is LOJIC ?
Louisville/Jefferson County Information Consortium
• Partnership...a cooperative effort to build
and maintain a comprehensive GIS for
Jefferson County, Kentucky.
• System...computer hardware, network,
spatial databases, applications, warehouse
of over 500 spatial databases.
• People...technical staff and near 1000 users
across local agencies and utilities.
Our Major Geospatial Databases
• Planimetric/Topographic Mapping - compiled at
1”=100’, 94 features, 2-3 year updates
• Property - 325,000 parcels, ownership, characteristics,
assessment, historical data, sales, daily updates
• Site Addresses / Street Address Ranges - daily updates,
basis for E911 and GIS geoprocessing applications
• Utilities - sanitary sewer, storm drainage, water, gas
• Planning - land use, form districts, zoning, preservation
districts, political/administrative/emergency districts
• Floodplain - FEMA Flood Insurance Rate Maps
• Aerial Photography / Digital Ortho-imagery
- 1-foot resolution color, 2-3 year update

Web-based GIS and public access
Our Challenge:
To use the web for public access to LOJIC GIS data to…
Where do I vote, who’s on the ballot?
How can I contact my local, state and federal elected officials?
What services and amenities are nearby?
Who owns this property?
Where are physical features and infrastructure?
How does stormwater drain across my property?
Where are recent crimes?
What’s the zoning and controls to my local land development?
What streets have been salted and plowed for snow?
How has our local landscape changed in recent years?
Where’s the closest survey control monument?
When is my garbage, yard waste, and junk pickup?
How can I review various maps without driving downtown?
