Site Files
The map.geojson file defines the latitude-longitude range over which the USGS computes
maps of seismic hazard from this model. The sites.geojson and sites.csv files
contain the test sites at which the USGS performs more detailed comparisons between model editions.
See the nshmp-haz user guide site specification section for more details on these files.
