The Frederick County GIS Team is pleased to provide several legacy online mapping applications for your use. 
Maps At A Glance - Browse information about Frederick County properties including real property information, plats, recycle data, crime statistics, zoning, water and sewer services, schools, libraries, police districts, and parks. Find an archive of historic imagery of the county ranging from 1952-2009, measuring tools, links to Google street view and Bing imagery, local weather forecasts and more.
Address and Street Search  -Search for streets and addresses, report errors.
Crime and Sexual Offenders - View selected offense reports taken by the Frederick County Sheriff's Office, the Brunswick Police Department, and the Thurmont Police Department. The application does not include any reports taken by the City of Frederick Police Department or the Maryland State Police. The information on the Registered Sexual Offenders has been provided to the Sheriff’s Office by the registrant and is based upon the last notification received.
Survey Control Network - View locations and information of survey control monuments in Frederick County. Use a variety of tools to measure and locate important information that can be printed and taken out into the field.
You can use your web browser to access maps that have been developed using ArcGIS Server with Adobe FLEX and ArcGIS Server with .NET technologies. Applications developed with Adobe FLEX require the user to install a free version of Adobe Flash 10 or later.
