Lost Creek Crest Characteristics 1999Field work to obtain data needed to develop this layer was carried out by Shoreland Solutions during late August-early September of 1996 and late August-early September of 1998. Specifically, the location and elevation of reference features including the vegetation line, toe of the foredune, crest of the foredune, toe of the bluff, and crest of the bluff were established at ~150 to 300 foot increments along the study area shoreline. V8-video images of the shoreline morphology was also collected at each of these locations. All elevations are referenced to the National Geodetic Vertical Datum (NGVD) of 1929. Categories within the attribute field Toe Character are defined as follows: talus (talus); no talus (not); open sand (os); hydrophillic vegetation (hveg); beach grass (grass); vegetated dune (vdune); driftwood (dw); cobble beach (cobble); shore protection structure (sps); seawall (SW); and riprap revetment (RR). Categories within the attribute field Vegetation Cover are defined as follows: less than 25% (25-); between 25 and 50 % (25+); between 50 and 75% (50+); and greater than 75% (75+).2_crest.met

Holiday Beach Shoretype 1999Based on a review of maps and field reconnaissance shoreline segments were classified as dune, bluff, slide, stream or inlet. Dunes are segments of shoreline backed by a sandy beach and dune. In this setting the extent of short-term shoreline change attributable to episodic wave attack events is the primary factor affecting shoreline stability. Bluffs are segments of shoreline backed by a sandy beach and bluff. In this setting the extent of short-term shoreline change attributable to episodic small-scale mass wasting events is the primary factor affecting shoreline stability. Slides are segments of shoreline where slide scarps, hummocky topography, and other morphologic features commonly associated with landslides back a sandy beach. In this setting the extent of short-term shoreline change attributable to episodic large-scale mass wasting events is the primary factor affecting shoreline stability. Inlets are segments of shoreline adjacent to and influenced by unaltered tidal inlets and their associated shoals. In this setting the extent of shoreline change attributable to inlet migration is the primary factor affecting shoreline stability3_shrtyp.met

Holiday Beach Orthophoto 1998A digital aerial photograph supplied by Spencer Gross Inc. in a TIFF (raster) image format. Reported to be a rectified orthophoto. it was photographed at a scale of 1:1200, resolution of ~1.33 feet per pixel. Each TIFF image has an accompanying 'world file' (.tifw or .tfw) which gives the affine coordinate transformation coefficients for the specific image. The original TIFF images were processed in ArcInfo. Image processing referencing the TIFF image to the 1983 State Plane Coordinate System, North Zone. It also involved clipping the original images to a desired size using the RECTIFY command with a defined BOX. A new 'world file' was produced for each clipped image.hbr.met

Aircraft Laser/GPS Mapping of Coastal Topography.Laser beach mapping uses a pulsed laser ranging system mounted onboard an aircraft to measure ground elevation and coastal topography. The laser emits laser beams at high frequency and is directed downward at the earth's surface through a port opening in the bottom of the aircraft's fuselage. The laser system records the time difference between emission of the laser beam and the reception of the reflected laser signal in the aircraft. The aircraft travels over the beach at approximately 60 meters per second while surveying from the low water line to the landward base of the sand dunes.lidar97.met
