The data are intended for use with GIS software. The ISGS uses ESRI ArcGIS software, however, ESRI formats can be imported into many different GIS software packages. It is expected that customers who obtain these data have the technical expertise to use GIS software. Th ISGS does not provide software support of any kind.
The ArcReader file (*.pmf) provides an interactive map that can be used to browse the data. It requires ArcReader 9.3, which can be downloaded free of charge from Esri here: http://www.esri.com/software/arcgis/arcreader.
