What each record holds, as the publisher describes it: 24 fields.
| Field | Description |
|---|---|
NLFID | Primary key field that is the basis for identifying unique roadway segments in ODOT's graphic roadway network. The attribute is made up of seven components that describe administrative and other characteristics related to a route segment; Positions (1) - Jurisdiction, (2 thru 4) - County Code, (5 thru 6) - Route Type, (7 thru 11) - Route Number, (12) - Extension Code, (13) - Description Code, (14) - Direction Code; For further definitions of codes, please refer to the Roadway Information Manual |
CTL_BEGIN_NBR | County logpoint number along the route on which the boring is located |
ODOT_DISTRICT | ODOT District of the borehole location |
COUNTY | County of the borehole location |
COUNTY_CD | The 3-letter code of the county within Ohio (88 counties total) |
ROUTE_TYPE | Two letter code indicating the basic transportation grouping or system that the route belongs to - third component of the NLFID |
ROUTE_NBR | Route number associated with the section of the route |
ROUTE_SUFFIX | Single letter used with the route number in local and municipal systems to guarantee uniqueness; For further definitions of codes, please refer to the Roadway Information Manual |
PERP_DATE | Calendar year in which a RI event occurs (like new constructions, abandoning of roads, annexations, increase in speed limit, and so on) on a roadway and is recorded in ODOT’s RI database. |
