Description:

Abstract:

A 1:62,500-scale black-and-white map identifying some 2,000 landslides of various types in Santa Cruz County, California, has been converted to a digital-map database that can be acquired from the U.S. Geological Survey over the Internet or on magnetic tape.

Purpose:

Knowledge of the distribution and type of landslides present in a region is one of the kinds of geologic information necessary for more effective land--use planning. This map provides such information. It is a preliminary map of known and suspected landslides prepared by stereoscopic analyses of high and intermediate level aerial photographs. Although prepared and published without the benefit of field checking for accuracy and completeness, this map is useful because it has quickly provided needed landslide information for immediate use in making land--use decisions.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Reliability of interpretations can be affected by the skill and experience of the aerial photo interpreters. Interpretations for this map were made by personnel with 5 to 10 years of aerial photo interpretation experience. The map, therefore, reflects the current state--of--the--art regarding interpretation of landforms of landslide origin from aerial photographs. Most of the landslide deposits shown on this map were interpreted from aerial photographs taken in 1963 and in 1970. This map is no more detailed than the aerial photographs and maps used. For this reason, small localized slides may be present which are not shown on the maps and some larger slides may not be shown because they are obscured by dense forest cover.

Logical_Consistency_Report:

The digital compilation was derived from linework inked directly by the authors on 17 USGS mylar greenline 7.5-minute (1:24,000-scale) quadrangle maps that cover Santa Cruz County.

Completeness_Report:

The mapped area only shows landslide deposits and doesn't show any bedrock geology.

Process_Step:

Process_Description:

The digital compilation was derived from linework inked directly by the authors on 17 USGS mylar greenline 7.5-minute (1:24,000-scale) quadrangle maps that cover Santa Cruz County. The inked linework for each source map was scanned (800 dots per inch), converted from raster to vector form, imported into ARC/INFO, and hand edited and combined into a single digital file. Small adjustments were made to fit lines across quadrangle boundaries, but larger misfits were retained. The base map for the landslide data includes topography, drainage, and culture at a scale of 1:125,000. These base layers were derived from USGS Bay Region Topographic Sheets (Aitken 1997).
