This data is a tool for analytical dynamic segmentation of all state owned or maintained highways for placement of features along the linear network in ArcGIS. This data provides a detailed view of the state highway system based on the Linear Referencing System (LRS) used by Oregon Department of Transportation.
This statewide file includes all state owned or maintained highways, spurs, connections, frontage roads, temporary traveled routes (TTR) and located lines.

Linear Reference System highway identifier. This is a representation of elements contained in the TransInfo (TI) database used to identify a highway, spur, connection or frontage road. The first nine characters are the inventory route numbers and the last three characters are the sub-route numbers.

Linear Reference Method highway identifier. This is a representation of elements contained in the TransInfo (TI) database used to identify a highway, connection or frontage road. The first five characters are the inventory route numbers and the last three characters are the sub-route numbers.

A code that is used to identify each unique instance of duplicate milepoints.
Oregon Transportation Management System (OTMS) GIS Base Layer Development Project (GIS01)
The number assigned to a roadway where more than one roadbed exists for the highway.
Oregon Transportation Management System (OTMS) GIS Base Layer Development Project (GIS01)
A unique identifier assigned to the roadway designating a spur, frontage road, connection or regular roadway.

A unique identifier assigned to an Oregon State highway.
Oregon Transportation Management System (OTMS) GIS Base Layer Development Project (GIS01)
The main road or highway identifier is a three digit numeric code. Frontage roads and connections are identified by the three digits plus a two alpha-character suffix code.

This statewide file includes all state owned or maintained highways, spurs, connections, frontage roads, temporary traveled routes (TTR) and located lines.This data is a tool for analytical dynamic segmentation of all state owned or maintained highways for placement of features along the linear network in ArcGIS. This data provides a detailed view of the state highway system based on the Linear Referencing System (LRS) used by Oregon Department of Transportation.This data is intended for use at scales of 1:24,000 or smaller.publication dateNoneNoneCall, email, or write.Geographic Information Services Unit, Oregon Department of TransportationHWYNAME, ST_HWY_IDX, ST_HWY_SFX, RDWY_ID, MLGE_TYP, OVLAP_MLGE, BEG_MP_NO, END_MP_NO, LRS, LRM_KEY and HWY_SEG_ID were obtained from ODOT's current TransInfo (TI) database. SHAPE was generated from ArcGIS software. RDWY_TYP, EFFECTV_DT, GIS_PRC_DT and SEG_EFF_DT were determined by the Geographic Information Services Unit.This file is complete at the time of posting and is dependent upon receipt of completed contract/construction information at the time of posting.Horizontal positional accuracy has been determined to meet or exceed NSDI map accuracy standards for 1:24,000 scale maps. Accuracy was determined by the combined use of USGS digital ortho photo quads and the NGS benchmarks to apply an accuracy statement to the highway linework via verification of known and visible NGS benchmarks on the orthoquads.See the highway accuracy worksheet for 1:24k highway baselayer on \\sn-salemmill-1\GIS\DATA\shp\docs\highway_accuracy_worksheet.xlsNo vertical positional accuracy has been determinedThe highway feature class was exported as a shapefile using Geomedia Pro v6.0: Warehouse > Export to > Shapefile. The file was then imported into ArcGIS where segment length was calculated and it became a measured shapefile.The shapefile was brought into ArcGIS where the attribute table structure was reviewed and where process and effective dates were added.TransInfo (TI) measurements are based on features located to +/- 0.02 mile.TransInfo (TI) measurements are based on features located to +/- 0.02 mile.hwynet_2011 contains HWYNAME, LRS, LRM_KEY, ST_HWY_IDX, ST_HWY_SFX, RDWY_ID, RDWY_TYP, MLGE_TYP, OVLAP_MLGE, BEG_MP_NO, END_MP_NO, EFFECTV_DT, HWY_SEG_ID, SEG_EFF_DT, SHAPE, and GIS_PRC_DT.Call, email, or write.This product is for informational purposes and may not have been prepared for legal, engineering or surveying purposes.
