90-0005 NCEER Strong-Motion Data Base: A User Manual for the Geobase Release (Version 1.0 for the SUN3) P.Friberg, K.Jacob 1990 Lamont-Doherty Geological Observatory 70 PB90-258062 10 The purpose of this report is to describe the initial implementation of a strong-motion data base developed by Lamont-Doherty Geological Observatory (Lamont) under the auspices of the National Center for Earthquake Engineering Research (NCEER). The report details how to install Lamont's data base access tool, GeoBase, and how to obtain strong-motion data. NCEER's strong-motion data base combines features never before available for a single strong-motion data base. These are: (1) both parametric and time-series data are accessible over a computer network; (2) the parametric data are maintained in a relational format; (3) the time-series data are stored on-line; and (4) the time-series are stored in a consistent format (Lamont's binary AH, Ad Hoc).
