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: 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: Administration: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.A weekly maintenance process dissolves out groups of like data into individual features. Features created in this process include: Jurisdictions, Hamlet Area, Zip Codes, Inspector Areas, Census Blocks, Magisterial Districts, State House, State Senate, US House, US Senate, Voting Precincts, Planning Area Boundaries, Urbanized Area, Future Land Use, EMS ORI, EMS Response Areas, FDID, Fire Response Areas, Fire Stations, Police Beats, Police Districts, Police ORI, Station Mutual Aid, School Districts, MS4, and Enforcement Zones.
Description: Tax Blocks are a subset of the County’s Tax Map hierarchy. A new block is created when a large subdivision is plated. Within the ParcelID string the tax block is represented by the 7thand 8thpositions. Seen in this example in capital letters: xx.xx-XX-xx.xx-xxxx.
Description: The Parcels feature is the geographic representation of cadastre records within the County as recorded in deeds and plats. The current parcels set is based off of the 1979 double circle maps by Wingate Appraisal & Mapping and digitized in the early 1990s. The data is continuously updated, as new land records become available. New parcels are added in a “best fit” methodology giving preference to the most current source. This feature is co-managed in AutoCAD and ArcMap. In Arc this polygon feature is part of a Editing topology along with our Zoning feature and our Administration feature. This prevents self-intersection and gaps, while ensuring complete coverage amongst the participating features.
Description: Municipal or local government laws that dictate how real property can and cannot be used in certain areas. Zoning laws limit commercial use of land in order to prevent oil, manufacturing or other types of businesses from building in residential neighborhoods. However, these laws can be modified or suspended if construction of the property will serve to help the community advance economically.All areas of land in Roanoke County have a zoning use restriction. This zoning polygon feature was created separately from our Parcel feature because some parcels have more than one zoning designation. The outside boundary of our zoning features match the outside boundary of our Parcel feature. This feature designates one of the the zoning areas as "Primary" to assign a zoning feature to our Assess Pro Real Estate system.It should also be noted that there are some areas of land inside the boundaries of Roanoke County that are actually located and taxed in adjacent jurisdictions. These areas have a psuedo parcelid and are included in the zoning feature. This polygon feature is part of a Editing topology along with or parcel feature and our Administration feature. This prevents self-intersection and gaps, while ensuring complete coverage amongst the participating features.
Description: This feature keeps track of all known building structures in Roanoke County. It is currently being maintained by GIS Services for all new structures. It was created from aerial digital images.It is currently maintained by the GIS Services Staff
