MarshType MarshType String 50 0 0 Tidal marshes take on several different morphologies. They can be embayed features that are set into the landscape with upland areas along the marsh edges. They can also be large extensive features that extend into the open water and have water on two or three sides. Fringe marshes grow nearly parallel to the shoreline and can be wide or narrow. An isolated marsh surrounded on all sides by open water; interior portions of the marsh may contain trees scattered at highest elevations In all cases, wetland vegetation must be relatively well established, although not necessarily healthy.

Four shape files combine to complete the Shoreline Inventory. The complete set includes va_lubc, va_astru, va_sstru, and va_newTMI. The va_lubc (land use and bank cover) file is a linear shape file containing data about land use, tree fringe, bank height, bank cover, bank stability and beach status along the shoreline. Va_astru (access structure shape file) is a point shape file with locations of docks, dilapidated docks, boathouses, and private and public boat ramps. Va_sstru (shoreline structures) is a linear shape file delineating hard structures in place at the shoreline (bulkhead, dilapidated bulkhead, riprap, wharf, unconventional, debris, marina < 50 slips, marina > 50 slips, jetty, marsh toe revetment, groinfield and breakwaters). Va_newTMI (tidal marshes) shows the location, size, and community type of tidal marshes. These shape files will be modified yearly with the addition of updated locality inventories. The PubYear field denotes the publication year of the county inventory. The jurisdiction is listed in the County field. Digital shoreline inventories began in 1998. Over the years, the methodology for collecting the data, as well as what data is collected has changed.

Surveys extended as far upstream as depth and field conditions allowed. Some additional data collection was performed by land where marshes were easily accessible from public lands. During surveys, marsh boundaries were verified, and wetland plant species observed within each marsh polygon were recorded along with relative cover estimates to determine marsh community types. Processing Dates: summers 2009-2015 Corrections were made to the digital data back at the lab using ArcGis Version 10.0 or above. Processing Dates: 2009 - present Tidal marshes were delineated from 2009, 2011 and/or 2013 VBMP imagery using onscreen digitizing techniques at a scale of 1:1,000. Bing and Google Earth online imagery were used to provide additional interpretive information to improve the accuracy of marsh boundaries. Marsh polygons were coded by shape and physiographic setting based on a classification system applied in the first Tidal Marsh Inventories (in the 1970s). Quality assurance and control measures were performed prior to generation of maps for fieldwork. Processing Dates: 2009-2015 2015-03-01T00:00:00 VBMP imagery, with the marsh polygon layer overlay, was printed for use in field surveys of the marshes. Processing Dates: 2009-2015 2015-04-01T00:00:00 Current Tidal Marsh Inventories (2010 to present) were merged together. 2016-02-17T00:00:00 Tidal marshes observed in the field are the only polygons to be coded for marsh community type. Field collection of marsh data was performed primarily from a small shallow-draft vessel. Surveys extended as far upstream as depth and field conditions allowed. During surveys, marsh boundaries were verified, and wetland plant species observed within each marsh polygon were recorded along with relative cover estimates to determine marsh community types. Polygons do not self intersect. Topology has been validated. There are no overlapping polygons, however, there may be small gaps between polygons.
