Lineage
Process Step
Process Description
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
