ELEVATION, LAT, LONGTD, HRZ_COL_M, CRD_RF_DTM, Shape, GIS_PRC_DT and EFFECTV_DT were determined by the Geographic Information Services (GIS) Unit. The file is complete at the time of posting. File was based on the accuracy of the TransInfo (TI) database and the existing road network. No vertical positional accuracy has been determined mileposts_2011 was created using a comma delimited text file (.txt) containing fields for HWYNAME, HWYNUMB, ST_HWY_SFX, RDWY_ID, MLGE_TYP, OVLP_CD, MP, MP_DESC, MP_DISP, LRS_KEY and LRM_KEY. Data was imported into an Access database and then dynamic segmentation was performed using Geomedia Pro 6.0. The resultant shapefile was exported and then manipulated using ArcGIS 10.0 to create ELEVATION, LAT, LONGTD, HRZ_COL_M, CRD_RF_DTM, Shape, GIS_PRC_DT and EFFECTV_DT 20120810 Road Inventory and Classification Services (RICS) Unit, Oregon Department of Transportation (ODOT).
