The stream DEM's were extracted by AMEC from a countywide subset of the USGS National Elevation Dataset (NED). This download package was compiled by the WVGISTC.</abstract><purpose>This data package may be useful to surveyors and/or engineers seeking to create local base flood elevations (BFE). BFEs so created may be a valuable contribution to Letters of Map Change (LOMC), including Letters of Map Amendment (LOMA) and Letters of Map Revision (LOMR). Some advanced knowledge, expertise and specialized software applications are required in order to use the included data.</purpose></descript><timeperd><timeinfo><rngdates><begdate>20100416</begdate><enddate>20130208</enddate></rngdates></timeinfo><current>Publication date</current></timeperd><status><progress>Complete</progress><update>As needed</update></status><spdom><bounding><westbc>-82.703386</westbc><eastbc>-77.657685</eastbc><northbc>40.63987</northbc><southbc>37.160858</southbc></bounding></spdom><keywords><theme><themekt>ISO 19115 Topic Category</themekt><themekey>elevation</themekey><themekey>environment</themekey><themekey>inlandWaters</themekey></theme><theme><themekt>None</themekt><themekey>floodplain model</themekey><themekey>digital floodplain</themekey><themekey>flood depth model</themekey><themekey>flood water surface elevation</themekey><themekey>advisory flood height</themekey></theme><place><placekt>None</placekt><placekey>West Virginia</placekey></place></keywords><accconst>Public, No Restrictions</accconst><useconst>No Restrictions</useconst><ptcontac><cntinfo><cntorgp><cntorg>West Virginia GIS Technical Center</cntorg><cntper>Eric Hopkins</cntper></cntorgp><cntpos>GIS Specialist</cntpos><cntaddr><addrtype>mailing and physical address</addrtype><address>West Virginia University</address><address>Department of Geology and Geography</address><address>PO Box 6300</address><address>Brooks Hall Rm. 330</address><address>98 Beechurst ave.</address><city>Morgantown</city><state>WV</state><postal>26501</postal></cntaddr><cntvoice>(304) 293-0557</cntvoice><cntemail>
