Beach, Dune
All processing steps for the shoreline inventory were generated using ArcGIS Pro 3.4.x while viewing conditions observed in the 2021 Imagery from the Virginia Basemap Program (VBMP) at a scale of 1:1000. Where available, imagery from VIMS Submerged Aquatic Vegetation (SAV) surveys (2022 - 2025) were consulted. Conditions were also verified using Google Earth Pro (2011-2025), Google Maps Street View, Bing Maps, and 2017 Imagery from the Virginia Basemap Program (VBMP). Beaches and dunes are delineated as polygons. The backside of the beach or dune is adjacent to the shoreline inventory upland shoreline and the water edge of the beach abuts the shoreline inventory water shoreline.

Beach/Dune inventories for 2024 and 2025 where appended and edge-matched to create one layer.

Polygons do not self intersect. Topology has been validated. There are no overlapping polygons, however, there may be small gaps between polygons.

BeachDune
Determines whether the shoreline is a beach or a dune.
Beaches are persistent sandy shores that are visible during high tides. These features can be wide or narrow. Beaches are coded as polygons with the water edge aligning with the water shoreline and the back edge aligning with the upland shoreline, tidal marsh edge, or the edge of the dune. Beach features coded along tidal marsh shorelines are persistent, sandy features located on the water side of tidal marsh vegetation. Sand washed into tidal marshes is not coded as a beach if the marsh vegetation &/or marsh edge is still clearly visible. This classification of beaches along tidal marsh shorelines can include professional judgment. Dunes are mounded accumulation of sandy soil at a higher elevation and grade than the beach. Dunes are generally located on the landward side of beaches and occasionally vegetated marshes. Dunes are vegetated with species such as beach grass, short dune grass, sea rocket, and Virginia pine (see Rivers & Coast Fall 2009 https://ccrm.vims.edu/publications/pubs/rivers&coast/Sp_Issue_rivers&coast10_09.pdf)

MapMyShore (MMS) is an application that allows the community to assist VIMS with collecting and ground-truthing shoreline inventory features critical to natural and cultural resources. Additions or updates to the inventory that come from MMS are noted in this field. Null values indicate the feature was not reported in MMS.

This layer defines where beaches and dunes are spatially located using polygon features. The attributes are explained in the Entity and Attribute Information section. 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. For detailed information on a particular county, please visit the Virginia Shoreline and Tidal Marsh Inventory web site at https://www.vims.edu/ccrm/research/inventory/virginia
