The map and database was produced at 1:24,000 scale (coordinate system NAD 1983, UTM zone 11N) using traditional field methods, interpretation of remote sensing images, and previous mapping. Field methods include description of landforms, deposit characteristics, and soil morphology. Stereoscopic analysis was conducted using 1:24,000 and 1:30,000 scale aerial photographs. Remote sensing images were used to evaluate topography and landforms. Process of deposition, geomorphic position, surface roughness, desert pavement maturity, soil morphology, and inset relations were used to classify Quaternary surficial deposits. All line work was compiled in ESRI's ArcMap® using referenced digital orthoquarter quadrangles (DOQQs) and topographic maps. The digitizing scale was approximately 1:3000. The database includes information on geologic deposits, samples, and geochronology.
Note: This metadata report provides an overview of the data content of this geodatabase. In addition, each feature class has a corresponding metadata report that should be referred to for additional Spatial Data Organization, Data Quality and Entity Attribute information.
Feature classes included in the geodatabase of the Surficial Geologic Map of a Calico Mountains Piedmont and Part of Coyote Lake, Mojave Desert, San Bernardino County, California are: geologic units (clco_poly), geologic contacts and faults (clco_arc) and samples for ostracode analysis or geochronology (clco_samples).
