 Data
This digital database was compiled with ArcInfo version 7.2.1 and consists of files containing geologic map and topographic base data in ArcInfo coverage and grid format. ArcInfo-compatible GIS software is, therefore, required to use the files of this database. The database is stored in a single zipped folder (bend.zip) in this release for ease of transfer. The scale of the source map limits the spatial resolution (scale) of the database to 1:100,000 or smaller. Available ArcInfo coverages and grids are described below:
ArcInfo
coverage or grid		 Description
  geo Contacts and rock units (lines, polygons)
  pt-features Volcanic vents, wells, and tephra samples (points)
  lin-features Fractured ground, crater rims, and flows (lines)
  faults Faults (lines)
  blue-iso Blue Lake crater tephra isopachs (lines)
  devils-iso Devils Hill chain tephra isopachs (lines)
  rock-iso Rock Mesa tephra isopachs (lines)
  map-boundary Boundary of map area (lines)
  topocult_base Topographic and cultural base (raster)
