vertical benchmarks

Data format: SDE Feature Class

File or table name: benchmark_vertical

Theme keywords: elevation, survey, benchmark, monument

Abstract: The location of vertical benchmarks throughout Napa County. Each is attributed with an elevation in NAVD 88 and NGVD 29. This data only contains Active Benchmarks, in the sloughs some Benchmarks have sank due to surface issues.

FGDC and ESRI Metadata:

Metadata elements shown with blue text are defined in the Federal Geographic Data Committee's (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM). Elements shown with green text are defined in the ESRI Profile of the CSDGM. Elements shown with a green asterisk (*) will be automatically updated by ArcCatalog. ArcCatalog adds hints indicating which FGDC elements are mandatory; these are shown with gray text.
