Purpose: These data are intended for science researchers, students, policy makers, and the general public. The data can be used with geographic information systems (GIS) software to display geologic and oceanographic information.

Although this Federal Geographic Data Committee-compliant metadata file is intended to document the data set in nonproprietary form, as well as in ArcInfo format, this metadata file may include some ArcInfo-specific terminology.

Logical_Consistency_Report: Chain-node topology present. Completeness_Report: Arcs are 'land' include everything that is not 'sea', so lakes are not separately identified.

Consequently, the shoreline of the quad with the > later date, the Mare Island quad, was held and the shoreline of the Cuttings > Wharf quad was manually adjusted to fit. > > Not all of the quadrangles were current, since we could not afford new mylar > sets.

This shoreline will be updated on an ongoing basis. > > The marine terminal facility known as Pacific Wharf situated on the east side > of San Pablo Bay alongside the main channel of the bay and west of the Unocal's > Wharf at Oleum (Mare Island Quad), was positioned from registered and rectified > air photos.
