This feature is an inventory of existing cemeteries in the County of Roanoke. It was researched by Thomas Katka with the Roanoke Regional Preservation Office with the Commonwealthof Virginia Department of Historic Resources and published in 2000. Chris Patriarca with the County of Roanoke Planning Department created this point feature in 2010. The GIS Staff maintains this feature and will add new cemeteries as they are determined.
The County of partnered with Woolpert to create this GIS feature. It is a point feature that documents all known addresses. It is the primary access point in our E-911 databases. It is also used to access property records in our GIS Maps and Apps gallery.
This feature includes a number of attributes that help identify where the address is located as well as the Common Name for the site and a Site Use Type that helps identify the Building Use at the site.
It is currently in full maintenence by the GIS Services Staff.
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 to dispatch E-911 calls.
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.
Simple polyline feature that is derived from digitizing the ourtline of the pavement at Roanoke Regional Airport.
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.
There are currently (2014) approximately 46,000 parcels in the County of Roanoke that are maintained by GIS Services staff on a real time basis.
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.
The basic drawings (maps) of the land cadastre (ownership boundaries) for all public and private lands. Roanoke County's parcel maps are typically maintained at three scales which show the layout of the basic land cadastre. They are related to legal description documents, which typically constitute the record for describing boundary ownership for a given parcel (e.g., metes and bounds descriptions). Parcel maps of an area provide more than a representation of ownership. The maps serve a wide range of purposes if they are constructed with a known level of positional accuracy and integrated with other cultural and physical information. Such databases are frequently used as a multipurpose cadastre.
There are currently (2014) approximately 46,000 parcels in the County of Roanoke that are maintained by GIS Services staff on a real time basis. This polygon feature was created by digitizing our existing pen and ink manual tax maps in the early 1990s. By 1998 all annotation features had been created and real time updates was realized.
This polygon feature is part of a Editing topology along with our Zoning feature and our Administration feature.
This Administration feature is the single most valuable feature maintained by the GIS Services staff. It combines the maintenance of many individual polygon features in one main overall feature.
It is part of a ArcGIS Topology class maintained with our parcel and zoning features in the Editing Feature Data Set.
We use the shared editing capabilities of this topology class to leverage our maintenance procedures as simply as possible.
Weekly, the individual features maintained with our Administration feature are created with ArcGIS dissolve function. These include Jurisdiction boundaries, Public Safety Response areas, Voting Precincts, Schools Attendance Zones, Inspections, Library Service Zones, and more.
Generally, maintenance of this feature is controlled thru shared editing performed with our parcel/zoning edits with the use of the Topology features in ArcGIS. Changes to features maintained in the Administration feature are caused by a number of issues. Parcel edits, new Public Safety Stations, changes in Voting Precincts, Police Reporting districts and other changes occur often. Most changes can be facilitated by selecting one or more “Administrative” polygons and changing the appropriate attribute value. Use of the “Cut Polygon” task may be necessary in those cases where part of a polygon must be changed from a district to another. The appropriate attribute can be changed in the affected area as necessary.
