Description Abstract This data set shows the sites of recent volcanic vents in the Mount Adams region (Scott and others, 1995). The points in this data set are not attributed. Nine registration marks are distributed over the data set. The coverage is in the universal transverse mercator projection.

ANY USE OF TRADE, FIRM, OR PRODUCT NAMES IS FOR DESCRIPTIVE PURPOSES ONLY AND DOES NOT IMPLY ENDORSEMENT BY THE U.S. GOVERNMENT.

Keywords: None.

Purpose This data set is intended for analysis, planning, and making maps of hazards. The vent sites do not mark an abrupt change between hazard and no-hazard areas, rather the degree of hazard decreases with increase of distance or elevation from the vent site.

Supplemental_Information Procedures_Used A stable base map with points was obtained from the authors. Latitude, longitude registration ticks were added to the base and used to orient the map on a digitizing tablet. Linework was collected in ArcEdit with digitizer inch units, a weed tolerance of 0, and a nodesnap set to closest 0.05 inches. A second coverage was created from the original. The decimal degree latitude and longitude values were substituted for the digitizer inch values in the second coverage. The second coverage was reprojected to a UTM projection with parameters of zone 10, units in meters, and a spheroid of Clarke 1866. The original coverage was transformed to the second projection to create a coverage in meters. RMS values were inspected after the transformation. The final coverage was plotted at the same scale as the base map, overlain on the basemap and checked for errors. The data set was renamed to admvent for Mount Adams vents.
