| description: | This feature class contains actual and "pseudo" drillholes used to create 3D geologic and geophysical models for the 2013 Portland NEHRP project. Drillhole points were digitized from maps or coordinates in drilling reports for geotechnical or other purposes (e.g. water wells, hydrocarbon exploration, etc). The drillhole feature class participates in two one-to-many relationship classes with tables of downhole geologic interpretations (PDX_NEHRP_interpretations) and shear-wave velocity measurements (PDX_NEHRP_Vs) using the key field "LOG_ID_concatenated". |
