<DT><I>Abstract:</I></DT>
<PRE ID="original">The Virignia Institute of Marine Science published the first Tidal marsh Inventories for Northampton County in 1977.   Using high resolution color infra-red imagery from 2009 a new Tidal Marsh Inventory has been developed.  2011.  Marsh boundaries were generated using heads-up digitizing techniques at a scale of 1:1,000.  Each marsh polygon was classified by morphologic type: fringe, extensive, embayed, or marsh island.  Marshes were ground-truthed in the field where a community type index was assigned to each marsh based on plant community make-up.  Each marsh was also coded with a marsh number which corresponds to the original 1977 delineation.  This will provide an opportunity to review changes that have occurred in the marshes over time.</PRE>

<PRE ID="original">The 2011 TMI (Tidal Marsh Inventory) shapefile was created by visual photo interpretation and heads up digitizing of recent (2009) high resolution (6") infrared aerial photography at a scale of 1:1000.  This scale was picked as a compromise between taking full advantage of the resolution and time constraints.  Marsh information from previous shoreline surveys was used, particularly in identifying narrow fringe marshes.  The latest NWI was also used.  This delineation was completed prior to the fieldwork and then corrected as noted in the field.</PRE>
