<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Shoreline for inventories published prior to 2015 were digitized along the land-water interface. Beginning in 2015, the inventory shoreline was digitized along the upland interface with water, marsh, or beach. To create a water interface shoreline for the post 2015 inventories, the upland shoreline was combined with the outlines of the Tidal Marsh Inventory polygons to produce a mapped shoreline that represents the boundary between the water and the upland, or the water and the marsh. This shoreline dataset is the result of combining the most recent digital water interface shoreline from inventories for Virginia. </SPAN></P></DIV></DIV></DIV>
The purpose of this product is to show the water interface shoreline that is developed for mapping tidal shoreline condition and tidal wetlands using recent imagery.

There are five shapefiles that are part of the Shoreline Inventory database: VA_lubc, VA_astru, VA_sstru, VA_tmi, and VA_beach. The VA_lubc (land use and bank cover) is a linear shapefile containing data about land use, bank height, erosion, bank cover, Phragmites australis, tree fringe, canopy overhang, marsh, and beach status along the shoreline. The VA_sstru (shoreline structures) is a linear shapefile delineating hard structures at the shoreline (bulkhead, breakwater, dilapidated bulkhead, debris, jetty, marina, marsh toe revetment, unconventional, riprap, groin fields). The VA_astru (access structures) is a point shapefile with locations of docks, ramps, dilapidated docks, outfalls, and boathouses. The VA_tmi (tidal marsh inventory) is a polygon shapefile that shows the location and community type of tidal marshes. The presence of beaches along the shoreline are shown in VA_beaches, a linear shapefile. The attributes of these five shapefiles are explained in the Entity and Attribute Information section below. Prior to 2012 the method of collecting data for the shoreline inventory was different. Data for marsh and Phragmites australis was recorded in the _lubc shapefile. Prior to 2016, beach was included in the lubc shapefile.

The inventories compiled here target tidal shoreline only. Access by boat is required for field surveys. Remote sensing techniques are used in areas where water depths are too shallow for access or where unmanaged, undeveloped shoreline persists along very long reaches. This would include headwaters of tidal creeks, and natural areas along park and conservation lands.
This dataset is updated annually with new or updated inventories. Not all Virginia localities with tidal shoreline have an inventory.
Imagery (2009, 2011, 2013, 2015, and/or 2017) serves as a background in the map portfolio. Used to accurately position land use and land cover data. Provided a new digital shoreline coverage that serves as the base shoreline for shoreline conditions. Used in the following counties: City of Virginia Beach, Northampton, Charles City, City of Suffolk, City of Poquoson, City of Newport News, Northumberland, City of Norfolk, James City County, City of Williamsburg, Gloucester, York, Stafford, Middlesex, Lancaster, City of Portsmouth, Prince George, Accomack, and City of Chesapeake. Added in 2017: Hanover, Surry, King George, City of Fredericksburg, Chesterfield, Isle of Wight, Spotsylvania, and Henrico. Added in 2018: Arlington, Caroline, Essex, New Kent, and Richmond Counties. Added in 2019: King and Queen, and King William.

Imagery (2007) serves as a background in the map portfolio. Imagery is used to update land use and structure data as well as to remotely code areas not previously surveyed in the field. The VBMP shoreline was also used and adjusted using the imagery where needed. This shoreline was used in the following counties: Mathews.

vector digital data
The shoreline for Northampton was extracted from the VGIN LiDar derived, hydro flattened DEM for the Eastern Shore using the ArcMap contour tool. Bank height was generated from the VBMP. The 0, 5, 10 and 30 foot contours were derived from the VBMP Eastern Shore hydrologically correct DEM based on the 2010 LiDar survey, using the raster surface contour tool. It was decided that the bank would be within 10 meters of the 0 contour except on some beaches where the bank was visually further away. 10 meter buffers were created for the 5, 10 and 30 foot contours. Each of these buffers was run with the 0 contour in the intersect tool to make files showing where the contours were within 10 meters of the 0. In no case did the 30 foot contour intersect 0. The 3 files for 0, 5, and 10 were run in the identity tool to make the final file showing bank height feature attributes of 0-5, 5-10, and 10-30. This was merged with the land use data and became an attribute in the shapefile.
2011-01-01T00:00:00
County inventories were merged together. Inventories completed during the year are appended to this dataset, either replacing older localities or filling in gaps. Annual updates are made at the end of the calendar year.
2016-02-25T00:00:00
All processing steps for the 2016 and 2017 shoreline inventories were generated using ArcGIS - ArcMap v10.2.2 while viewing conditions observed in 2015 Bing high resolution oblique imagery and 2013 imagery from the Virginia Base Mapping Program (VBMP). Using the latest VBMP 2013 imagery as a background, conditions visible on shore were used to code a digital shoreline created using VBMP 2013 imagery at a scale of 1:1000. Conditions were also verified using Bing Birds Eye, VBMP 2011, and VBMP 2009 imagery. For the land use/bank cover shapefile arcs were split and coded for land use, bank height, bank cover, and tree fringe. The following localities published in 2017 were added to this dataset: Chesterfield County, City of Colonial Heights, City of Fredericksburg, City of Petersburg, City of Richmond, Hanover County, Henrico County, Isle of Wight County, King George County, Spotsylvania County, and Surry County.
2017-12-20T00:00:00
All processing steps for the 2018 shoreline inventories were generated using ArcGIS - ArcMap v10.4 while viewing conditions observed in Bing high resolution oblique imagery, Google Earth, and 2017 imagery from the Virginia Base Mapping Program (VBMP). Using the latest VBMP 2017 imagery as a background, conditions visible on shore were used to code a digital shoreline at a scale of 1:1000. Conditions were also verified using Bing Birds Eye, VBMP 2011, VBMP 2013, and VBMP 2009 imagery. For the land use/bank cover shapefile arcs were split and coded for land use, bank height, bank cover, and tree fringe. The following localities published in 2018 were added to this dataset: Arlington County, Caroline County, Essex County, New Kent County, and Richmond County. King and Queen County and King William County were published and added in 2019.
2019-04-03T00:00:00
Topology has been validated. There are no overlapping or self-intersecting arcs. There will be dangles at some locality boundaries and along some waterways where digitizing stopped. Inventories prior to 2015 used shoreline drawn along the land/water interface. Inventories created since 2015 use shoreline drawn along the upland edge (upland/marsh interface or upland/water interface).

Five shape files combine to complete the Shoreline Inventory. The complete set includes va_lubc, va_astru, va_sstru, va_beach, and va_TMI. 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-beach is a linear shapefile showing the presence of beaches on the shoreline. Va_TMI (tidal marsh inventory) 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.
