Augustine Island (volcano) in lower Cook Inlet, Alaska, has erupted repeatedly in late-Holocene and historical times. Eruptions typically beget high-energy volcanic processes. Most notable are bouldery debris avalanches containing immense angular clasts shed from summit domes. Coarse deposits of these avalanches form much of Augustine's lower flanks. This geologic map at 1:25,000 scale depicts these deposits, these processes. Purpose: This database was constructed in order to produce a geologic map of Augustine Volcano as a basis for understanding processes and volcano hazards involved in the eruptions of Augustine Volcano. Supplemental_Information: All the geologic map information used to publish U.S. Geological Survey Professional Paper 1762 is contained in this digital publication. The geologic map plates in Professional Paper 1762 show the distribution and relations of volcanic units at Augustine Volcano. This metadata document contains information for the entire set of ArcGIS feature classes included in this database. Where relevant information for individual feature classes differs from that of the others, each feature class is documented separately in sequence in the corresponding metadata section.

Although the digital form of the data removes the constraint imposed by the scale of a paper map, the detail and accuracy inherent in map scale are also present in the digital data. The fact that this database was edited for a scale of 1:25,000 means that higher resolution information is not present in the dataset. Plotting at scales larger than 1:25,000 will not yield greater detail, although it may reveal fine-scale irregularities below the intended resolution of the database. Similarly, where this database is used in combination with other data of higher resolution, the resolution of the combined output will be limited by the lower resolution of these data. Acknowledgement of the U.S. Geological Survey would be appreciated in products derived from these data.

Waitt (Waitt and Beget, 2009). David W. Ramsey and Evan Thoms converted the database from Arc/Info 7.2.1 coverage format to ArcGIS 9.3.1 geodatabase format for release. David W. Ramsey updated the geodatabase, created the metadata, and provided the GIS-expertise to bring the database and metadata to completion. Native_Data_Set_Environment: Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 3; ESRI ArcCatalog 9.3.1.3000 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: See Entity_Attribute_Information Logical_Consistency_Report: Polygon and arc (chain-node) topology present in appropriate ArcGIS feature classes. Other feature classes are point or line exclusively and do not require topologic relationships. Completeness_Report: The report is intended to describe completely the spatial extents of igneous and volcanic products and structural features of Augustine Island, Alaska. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The general positional accuracy of each line in the database is indicated qualitatively within the LTYPE field in the attribute tables of each feature class (see Attribute_Domain_Values). Points in the database are generally well located. The position of each data item is derived from USGS 1:25,000-scale topographic base maps, and therefore inaccuracies encountered are within National Map Accuracy Standards at the publication scale of each map plate. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: No vertical positional data recorded Process_Step: Process_Description: Geologic linework was compiled on USGS 1:25,000-scale topographic maps by Richard B. Waitt. The linework was then scanned at 400 dpi, georeferenced, converted to vector data using the Arc/Info command GRIDLINE , and edited on-screen to repair errors visible at map scale by Jacqueline McIntire and David W. Ramsey. Polygon topology was created and each arc and polygon tagged on-screen. Plotfiles were created in ArcPlot by Jacqueline McIntire and were updated in Adobe Illustrator by Christine G. Janda. The database was converted from ArcInfo 7.2.1 coverage format to ArcGIS 9.3.1 geodatabase format by David W. Ramsey and Evan Thoms with corresponding metadata creation by David W. Ramsey.
