Description: Address Points contain a single dot for each address or point of interest within the County. This feature is used as the primary despatch source in the County's E911 CAD System. The Street Address subtype includes addresses and "0" address placeholders, which represent parcels and addressed structures. If a structure is present the address point appears within the building footprint, otherwise the point is located at the geographic center of the parcel. Multiple non “0” addresses can be associated with a given parcels, where there are multiple structure and or Real Estate Cards. The Point of Interest subtype is reserved for named places and features that are not tied to a parcel. Some examples of a Point of Interest include: bridges, hazardous curves in a road, entrances to subdivisions, and mile markers. Either subtype can contain civic location, coordinate pairs in multiple projections, common name, and site type information.
Description: Point feature used to denotethe location of Elementary, Middle and High Schools in the County of Roanoke.Created as a subset of Community Facilities.Community Facilities contains a point for public locations within Roanoke County and the surrounding localities. These points fall into the following categories: Schools, Parks & Rec, Polling Places, Public Safety, Libraries, Administration, General Services, Post Offices, Hospitals, and Museums. Each location is attributed with hours of operation, contact info, and URL reference. Subset categories are extracted to create standalone features such as School Sites in the Schools Dataset

Description: The polyline feature is used to inventoy our Street Centerlines in Roanoke County. The individual polygon objects mirror our Adddress Block Ranges. Also includes attributes on lower and upper address ranges, functional classes, speed limits and others. Used as a secondary dispatch source for E911 calls.
Description: This simple polyline freature was digitized by GIS Services staff form our 2011 aerial photography and includes Roanoke County and all adjacent jurisdiction areas. This includes track owned by Norfok Southern and the CSX.

Description: Magisterial Districts are administrative county division by which the County Board of Supervisors are elected.Magisterial Districts are maintained within the Administration Feature and is dissolved out weekly.Administration is a polygon feature consisting of the smallest statistical areas bounded by visible features such as roads, streams, railroad tracks, and mountain ridges, as well as by nonvisible boundaries such as jurisdictional limits, school district, public safety boundaries, voting precincts, and census blocks. This methodology allows for single stream editing to move coincidental boundaries across many aggregate datasets simultaneously. Administration is maintained though an ArcGIS topology class in conjunction with County Parcels and Zoning. The topology prevents self-intersection and gaps, while ensuring complete coverage amongst the participating features.
