This layer's FGDC category description is: Elevation and bathymetry

Data Set Description: Elevation contour lines at 25' intervals

Non-standard Attributes in table:

  • U_ID--provides the user with a unique number for each contour line in the layer
  • Dxf-layer--coded by the producers of the layer, this provides detailed info regarding each contour line, such as whether the line runs under a tree, or if it represents a bathymetric contour, etc. The code is as follows: 800 = normal index contour, 802 = hidden, 804 = dashed (under trees), 806 = other interval, 808 = bathymetric, 810 = depression, 812 = hidden depression (under bldg), 814 = dashed depression (under trees), 816 = other depression interval, 818 = bathymetric depression.
  • Dxf-elevation--this is the elevation of the contour line

Data Source History: The data set was supplied by Oakland's Public Works department in the form of 306 tiled Autocad files. Jake Schweitzer converted from DXF files to coverages via ArcInfo's DXFARC command and several batch scripts in the UNIX bourne shell language.
