display:none"> <I>Process description: </I>Digital NOS T-sheets are used for the "early date". This provides the state with a standardized early date used by other researchers and adopted by the USGS in their recent shoreline erosion studies. In addition, using the NOS T-sheets for the "early date" eliminates the problems introduced by the variable error in the early date in the COAST database as discussed in the supplementary report to the 1992 Methods Report (Benton et al. 1997). NOS T-sheets do not exist for approximately 30 miles of shoreline north of Oregon Inlet. For approximately 20 miles of this shoreline, the early date was established by rectification of the 1940 photoset using ERDAS Imagine OrthoBASE. This method of photorectification provides digitally rectified mosaiced images with continuous coverage over the project area. The accuracy of the rectified images is a function of the photo scale, the map scale and the number, distribution and quality of the ground control points used. The 1949 NOS T-sheets used north of Oregon Inlet terminated about eight miles north of the inlet in South Nags Head. North of this area to the Virginia border, T-sheets of this time period are not available. Therefore, one task of the project was to acquire and geo-rectify appropriate historical photography for this area. Historical photography was located at the Corps of Engineers, Wilmington District, and borrowed for use on this project. Suitable photography was defined as that originating in the 1940s, having a shore parallel flight line, having a minimum of 30 percent overlap, having less than 1:24,000 scale, providing coverage in the appropriate area and not being associated with a storm. Photos taken in October of 1940 fulfilled these requirements with the exception of coverage. The 1940 photos stop about 10 miles south of Virginia requiring that additional work would have to be done to fill in a shoreline in this area. Because of the lack of readily identifiable features suitable for use as control points on the 1940 photos or the area, an intermediate set of photographs was rectified. This enabled the technician to follow features through time to determine the best possible the ground control points. The 1962 post Ash Wednesday Storm photo coverage was used for this "step-back" procedure. Though not suitable for long-tem erosion analysis, this set is ideal for assisting in determining ground control points for use in rectifying the 1940 photos. The northernmost 10 miles of shoreline was not covered by either the NOS t-sheets or the 1940 photos. While the 1962 photos did extend through this area, an examination of the rectified images confirmed that the post-storm shoreline was not suitable for the long-term shoreline erosion rate update. Therefore, on consultation with DCM staff, the determination was made to use the COAST data for this small stretch.<BR /> <I>Process date: </I>2003 <BR /> <DIV CLASS="ph1" onmouseover="doHilite()" onmouseout="doHilite()" onclick="hideShowGroup(this)">Who did this process <DIV CLASS="pe2" STYLE="display:none"> Steve Benton<BR />NCDENR - Division of Coastal Management<BR /><I>mailing address:</I><BR /><DIV STYLE="margin-left:0.3in"> <DIV CLASS="lt"> <PRE ID="original">1638 Mail Service Center</PRE> <SCRIPT>fix(original)</SCRIPT> </DIV> <DIV> Raleigh, NC 27699-1638</DIV> <DIV>US</DIV></DIV> <BR /> 919.733.2293 (voice)<BR />919.733.1495 (fax)<BR />steve.benton@ncmail.net<BR /><BR /> <DIV><I>Hours of service:</I> 8:00 AM to 5:00 PM, EST (Monday - Friday)</DIV><BR /> </DIV> </DIV> <BR /></DIV> </DIV> <DIV CLASS="ph2" STYLE="margin-left:0.4in" onmouseover="doHilite()" onmouseout="doHilite()" onclick="hideShowGroup(this)">Process step 2 <DIV CLASS="pe2" STYLE="margin-left:0.2in; display:none"> <I>Process description: </I>Metadata imported.<BR /> <I>Source used: </I>C:\TEMP\xml6E.tmp<BR /> <BR /></DIV> </DIV> <DIV CLASS="ph2" STYLE="margin-left:0.4in" onmouseover="doHilite()" onmouseout="doHilite()" onclick="hideShowGroup(this)">Process step 3 <DIV CLASS="pe2" STYLE="margin-left:0.2in; display:none"> <I>Process description: </I>Dataset copied.<BR /> <I>Source used: </I>\\GISNT2\GIS\CAMA.mdb<BR /> <BR /></DIV> </DIV> <DIV CLASS="ph2" STYLE="margin-left:0.4in" onmouseover="doHilite()" onmouseout="doHilite()" onclick="hideShowGroup(this)">Process step 4 <DIV CLASS="pe2" STYLE="margin-left:0.2in; display:none"> <I>Process description: </I>Dataset copied.<BR /> <I>Source used: </I>\\GISNT2\GIS\CAMA.mdb<BR /> </DIV> </DIV> <DIV CLASS="pn" STYLE="margin-left:0.4in">Sources</DIV> <DIV CLASS="ph2" STYLE="margin-left:0.6in" onmouseover="doHilite()" onmouseout="doHilite()" onclick="hideShowGroup(this)">Source 1: North Carolina State University Department of Civil Engineering <DIV CLASS="pe2" STYLE="margin-left:0.2in; display:none"> <I>Media: </I>Digital NOS T-Sheets<BR /> <I>Scale denominator: </I>NOS T-Sheets From 1:10K to 1:20K / Early Photography 1:24000<BR /> <DIV CLASS="ph1" onmouseover="doHilite()" onmouseout="doHilite()" onclick="hideShowGroup(this)">Currentness of this source <DIV CLASS="pe2" STYLE="display:none"> <DIV><I>Date and time: </I> 2003</DIV> </DIV> </DIV> </DIV> </DIV> <BR /> <DIV STYLE="margin-left:0.2in" CLASS="pn">ESRI geoprocessing history</DIV> <DIV CLASS="ph2" STYLE="margin-left:0.4in" onmouseover="doHilite()" onmouseout="doHilite()" onclick="hideShowGroup(this)">1.

T-sheets were used to obtain "Historic Shorelines". This provided a standardized early shoreline date; which is used by other researchers and adopted by the USGS in other recent shoreline erosion studies. In addition, using the NOS T-sheets for the "early date" eliminates the problems introduced by the variable error in the early date in the COAST database as discussed in the supplementary report to the 1992 Methods Report (Benton et al. 1997). T-sheets do not exist for approximately 30 miles of shoreline north of Oregon Inlet. For approximately 20 miles of this shoreline, the early date was established by rectification of the 1940 photoset using ERDAS Imagine OrthoBASE. This method of photorectification provides digitally rectified mosaiced images with continuous coverage over the project area. The accuracy of the rectified images is a function of the photo scale, the map scale and the number, distribution and quality of the ground control points used.</PRE></SPAN> <SCRIPT>fix(original)</SCRIPT><BR /> </DIV> <BR /> </DIV> </DIV> <CENTER><FONT COLOR="#FFFFFF" SIZE="1">Copyright 2006 | NC Division of Coastal Management | 400 Commerce Ave. | Morehead City, NC 28557 | 1-888-4RCOAST</FONT></CENTER> </BODY> </HTML>
