Road Centerline
Oakland County
Oakland County
vector digital data
This line feature class is a spatial representation of named road centerlines in Oakland County. This feature class was originally created through stereo compilation using Oakland County's 1997 orthophotography as reference. Key attributes include left and right address ranges and cartographic name.
This primary purpose of this data set is to support computer aided dispatch (CAD) for emergency response and other geocoding projects. It is also useful for cartographic output and spatial analysis.

For traveled ways that existed at the time of the orthophotography, the geometry was constructed during stereo compilation. For traveled ways that were constructed after the orthophotography, sources include more recent imagery, construction drawings, and surveys. The road names and address ranges were compiled initially from TIGER95 files. These values were then verified from independent sources and checked by city, village, and township representatives. The road segmentation was developed to optimize addressing, dispatching, and standardization of road names. The segmentation in this file will not correspond directly to TIGER segmentation. Address range values will correspond with the direction of the arc. "Low" address values will be assigned to the "From" nodes, "High" address values will be assigned to the "To" nodes. Road segments that do not have an address assigned to them may be populated with a "0" in the following fields: FromAddressLeft, ToAddressLeft, FromAddressRight, ToAddressRight. Naming and database design standards have been established for limited access thoroughfares such as interstates and state highways and their ramps. Numeric abbreviations (I75, I696, M24) will be the primary highway name identifier. Interstate and ramp identification conventions have been developed to consistently code on-ramps, off-ramps, connectors and collectors. Those ramps that connect two interstates and state highways are classified "connectors" (CONN). Service drives, which are local access roads that parallel interstates, are classified "collectors" (COLL). Those ramps that provide access to interstates from local roads, or vice versa, are classified "on-ramps or off-ramps" (ONRP, OFRP). These values are present in the StreetType field.
Road centerlines are digitized using road right-of-ways that are maintained in the parcel feature dataset and/or orthoimagery as a reference theme. The additions are prompted through parcel maintenance or notification from the local jurisdiction. Address range and other attributes are verified against the site address and other external sources.
In September, 2010, the new data model of the road centerline was released. There were changes to the RoadCenterline field names, along with the addition of a network dataset that can be used for routing purposes.
