contours, 10 ft interval, non-watershed area

Data format: Shapefile

File or table name: cont_02_400

Theme keywords: elevation, Contours, Contour line, Hypsography, Landform, Topography

Abstract: Elevation Contours of Napa County for non-watershed Area, 10 foot interval. These are the 10 ft contours produced during the 2002/2003 Orthophotography Project. The area covered by this data is referred to as the Non-watershed Area because it lies outside the Napa River Watershed. The contours were mapped at a scale of 1"=400ft and meet National Map Accuracy standards at this scale. The vertical datum for the contours is NAVD88.

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.

Data Quality Information:


Logical consistency report:
Unknown

Completeness report:
Contour mapping was derived by algorithmic interpolation of the DTM, using TerraModel v.9.6 software.  Some line smoothing and manual displacement of contours was performed to enhance the cartographic expression of the representative data. This layer is 10 foot contours of the Napa Non- Watershed. area which is  roughly the eastern half of the county. For contours of the western half of the county see the "Contours 5 ft interval Watershed area" layer.
