GIS data layers case 1, case 2, and case 3 were delineated by scientists at the Cascade Volcano Observatory and depict various lahar innundation zones around the mountain. The lahar hazards were defined by field investigations and construction of cross sections. For examples and descriptions of field investigations and cross section construction, see Scott and Vallance (1995) and Scott and others, (1995). Two additional GIS layers were created that show post-lahar sedimentation and pyroclastic flow zones. These coverages are titled postlahar and pyroclastic.

Purpose: These volcanic hazard zones are intended for use by public and private agencies to view, overlay with other Geographic Information System (GIS) data sets, and make maps of volcanic hazards from potential future eruptions of Mount Rainier, Washington. It is critical to understand the nature of the boundaries of the volcanic hazard zones. Although arcs serve as boundaries of hazard zones, the degree of hazard does not change abruptly at these boundaries. Rather, a volcanic hazard decreases gradually with increased distance from the volcano and above the valley floor. These volcanic hazards also span a range of size and recurrence. The hazard zones delineated in this data set portray volcanic events believed most likely from future activity at Mount Rainier, Washington. Areas outside the hazard zones, especially those having low relief, should not be regarded as hazard-free. Too many uncertainties exist in source, size, and mobility of future events to locate boundaries of zero-hazard zones with confidence.

The vectors in this data set were compiled and checked for accuracy at a scale of 1:100,000 and thereby should only be used at 1:100,000 or smaller scales. The data set is inappropriate for use at scales larger than 1:100,000. Doing so will produce inaccurate and unreliable results.

Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Original linework were compiled on mylar greenlines of U.S. Geological Survey topographic quadrangles created according to National Map Accuracy Standards. Digitized linework were plotted, registered to original linework, and inspected visually for discrepency of greater than a linewidth (approximately 0.007 inches). For computer modelling, Digital Elevation Models having cell sizes of about 62 ground meters or about 2 millimeters on the map at 1:100,000 scale were derived from Digital Line Graph contour layers that were created according to National Map Accuracy Standards. All linework was plotted with DLG contour layers to check for positional accuracy as are reasonable according to geologic and hydrologic principles. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: 1:100,000 scale Digital Line Graph (DLG) contours have contour intervals of either 50 or 40 meters as well as Digital Elevation Models have vertical accuracies according to the National Map Accuracy Standards. All linework was plotted with DLG contour layers to check for positional accuracy as are reasonable according to geologic and hydrologic principles. Lineage: Process_Step: Process_Description: Linework was captured by hand digitizing. Digitizing procedures: Arcs were digitized in tablet inches from lines inked on 1:24,000 or 1:100,000 scale topographic mylar greenlines. Each quadrangle was registered to the digitizer and re-registered to ensure that tics could be relocated with an RMS equal to or less than 0.004. Lines were digitized using a NODESNAP CLOSEST .05 and a weed tolerance of 0. A second coverage was CREATEd from the first. In INFO, the tics were changed from inch coordinates to decimal degree coordinates and saved. The decimal degree coordinate coverage was converted to a UTM projection using: INPUT PROJECTION GEOGRAPHIC UNITS DD PARAMETERS OUTPUT PROJECTION UTM UNITS METERS ZONE 10 PARAMETERS END Each coverage in inches was TRANSFORMed to the empty UTM coverage ensuring the transformation RMS was equal or less than 0.004 inches. The individual coverages were edgematched and merged into a single coverage. Coverages were checked for digitizing accuracy both before and after merging by plotting linework at 1:24,000 or 1:100,000 scale as appropriate and overlain on original linework.

Distribution of the database files assumes that all components of the database will be used together. Use of any one ArcInfo coverage outside the context of the other coverages is considered inappropriate or misuse. Due to the uncertainty involved in the prediction of lahar-inundation limits, individual coverages do not delimit a well-defined range of hazard. The collective group of the ArcInfo coverages better convey the gradational nature of hazard zones.
