These data provide an inventory of predominantly historic landslide deposits and debris flow paths in North Carolina. These Landslide Footprints differ from Deposits in that their origins are distinctly from a landslide with clearly identifiable source area and features (headscarp, lateral scarps, and toe). Landslide Footprints have an associated Landslide Record (point feature class) that describe the slope movement feature and is placed at the approximate Head Scarp or zone of initiation of the landslide feature. The data is presented by the North Carolina Geological Survey. Mapping is ongoing. |

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Landslide Features show the approximate areal extents of relatively recent, individual slope movements where their initiation (source) areas are known. Landslide Features are mapped from field investigations, features visible in various vintages (1940–most current) of aerial photography and orthophotography, and a variety of derivatives from Light Detecting And Ranging (LiDAR) digital elevation models (DEM). </SPAN><SPAN>Head Scarp, lateral scarps, and the toe of a feature must be identifiable in remote and/or field mapping before a feature is designated as a Landslide Feature.</SPAN><SPAN><SPAN> </SPAN></SPAN><SPAN>All Landslide Features are paired with at least one Landslide Location (point) at the Head Scarp or Initiation Zone of the feature, for two reasons: 1) the Landslide Location contains details about the release surface and the type of material that has moved; 2) we can show a county or region-wide spatial distribution of landslides as Landslide Locations (point) on a smaller-scale map by setting the size of the points so they are legible on a large area map in such a way that would not be possible with Landslide Feature polygons.</SPAN></P></DIV></DIV></DIV> |
