- Abstract
- The two CD-ROM's in this product provide three basic sets of information to the user (1) map files, (2) hazard curve data, and (3) spectral response acceleration data. The hazard curve and spectral response acceleration data may be obtained in tabular or graphical form by specifying a site location by latitude-longitude or zip code. They also contain the map files for the four map sets described earlier. The data base used with these CD-ROM's are the same as that were used to prepare the maps. The parameters used to prepare each map were calculated on a grid for the areas to be mapped, the maps were then constructed by contouring the 'gridded data'. The grid spacing was 0.1 deg for the 48 conterminous states (except Region A, which was also calculated at a grid of 0.05 deg) and Alaska. Hawaii maps were constructed using calculations at a grid spacing of 0.02 deg.
