This layer contains the obscured contours for Campbell County, Virginia. Contours for the project meet accuracy specification for 2' contours and 4' contours based on the source 1\"=600' and 1'=1,200' photography, respectively. In areas of dense vegetation or shadow, it may be impossible for the stereo compilation technician to accurately see the ground. The operator places masspoints as best as possible, extending breaklines through shadowed areas or placing points on the ground as is visible through the vegetation. Since the ground is obscured, the contours cannot be guaranteed to meet accuracy specifications for the specified contour interval.<\/SPAN><\/SPAN><\/P>
