Title: Essex County: Land Use and Bank Cover 2018

Geospatial_Data_Presentation_Form: vector digital data

Description:

Abstract:

Shoreline Situation Reports (SSR) were first generated by VIMS in the 1970's to report the condition and status of the shore lands. The SSR series were published in hardcopy on a county by county basis for each Tidewater Virginia localities. The reports were intended to assist planners, managers, and regulators in decisions pertaining to management of coastal areas and natural resources therein. This Shoreline Inventory report continues a process which updates and expands the earlier reports. Data collected reports conditions surveyed in the immediate riparian zone, the bank, and along the shoreline.

Purpose: To inventory Virginia's tidal shoreline conditions.

Supplemental_Information:

There are five shapefiles assocaited with Essex County inventory database: Essex_lubc_2018, Essex_astru_2018, Essex_sstru_2018, Essex_tm_2018, and Essex_beaches_2018. Essex_lubc_2018 (land use and bank cover for Essex County) is a linear shapefile containing data about land use, tree fringe, bank height, bank cover, bank stability and beach status along the shoreline. Essex_sstru_2018 (Essex County shoreline structures) is a linear shapefile 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). Essex_astru_2018 (Essex County access structures) is a point shapefile with locations of docks, dilapidated docks, boathouses, and private and public boat ramps. Essex_tm_2018 (Essex County tidal marshes) shows the location, size, species and type of tidal marshes in Essex County. Essex_beaches_2018 is a linear shapefile showing the presence of beaches on the shoreline of Essex County. The attributes of these five shapefiles are explained in the Entity and Attribute Information section below.

These data should not be used for jurisdictional permit determinations beyond providing general shoreline condition or status information. These data have not been surveyed to property boundaries.The Comprehensive Coastal Inventory Program (CCI) at VIMS performs a service by distributing data generated by either CCI or public agencies which offer data without restriction or charge. CCI assumes no responsibility for data accuracy or precision, metadata completeness or correctness for digital information. CCI assumes no liability for misuse of any data which may arise as a result of any alteration, conversion, or combination with other data sources. As well, the timeliness and scale of these products must be considered when evaluating appropriate use.

Lineage:

Process_Step:

Process_Description:

A shoreline for Essex County was created using the 2017 Virginia Base Mapping Program (VBMP) imagery at a scale of 1:1000 as a backdrop and using ArcGIS version 10.4. Using this as a baseline, the shoreline inventory was remotely generated using two sources: Google Earth imagery and high resolution imagery available through Bing Maps.

Process_Date: 20170831

Process_Step:

Process_Description:

All processing steps for the shoreline inventory were generated using ArcGIS - ArcMap v10.4 while viewing conditions observed in Bing high resolution oblique imagery and 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, created at a scale of 1:1000. Conditions were verified using Bing Birds Eye and VBMP 2009 and 2013 imagery. For the land use/bank cover shapefile, arcs were split and coded for land use, bank height, bank cover, tree fringe, and presence or absence of spit. For the beaches shapefile, arcs were coded for the presence or absence of a beach. For the access structure shapefile, arcs were coded for dock, dilapidated dock, boathouse, public ramp, and private ramp. For the shoreline structure shapefile, arcs were coded for bulkhead, delapidated bulkhead, riprap, unconventional, debris, wharf, breakwater, groinfield, jetty, marsh toe revetment, and marina >50 slips and <50 slips.

Process_Description:

The first and second step in the QAQC process involves complete checks of shoreline coding by a GIS Programmer/Analyst and a Marine Scientist.

Attribute_Domain_Values:

Enumerated_Domain:

Enumerated_Domain_Value: Agriculture

Enumerated_Domain_Value_Definition:

Land use defined as agricultural includes farm tracts that are cultivated and crop producing. This designation is not applicable for pastureland, which is coded as "grass".

Enumerated_Domain_Value_Definition_Source:

VIMS Shoreline & Tidal Marsh Inventory Glossary, Center for Coastal Resources Management

Enumerated_Domain:

Enumerated_Domain_Value: Bare

Enumerated_Domain_Value_Definition:

Land use defined as bare includes areas void of any vegetation or obvious land use. Bare areas include those that have been cleared for construction.

Enumerated_Domain_Value_Definition_Source:

VIMS Shoreline & Tidal Marsh Inventory Glossary, Center for Coastal Resources Management

Enumerated_Domain:

Enumerated_Domain_Value: Commercial

Enumerated_Domain_Value_Definition:

Commercial is a land use classification denoting small commercial operations such as shops, restaurants, as well as campgrounds. These operations are not necessarily water dependent businesses.

Enumerated_Domain_Value_Definition_Source:

VIMS Shoreline & Tidal Marsh Inventory Glossary, Center for Coastal Resources Management

Enumerated_Domain:

Enumerated_Domain_Value: Forested

Enumerated_Domain_Value_Definition:

Forest cover includes deciduous, evergreen, and mixed forest stands of trees. The land use is classified as "forested" if there is a dense cover of trees and no other land use category is apparent close to the shoreline, e.g. residential, commercial, industrial, agriculture, etc.

Enumerated_Domain_Value_Definition_Source:

VIMS Shoreline & Tidal Marsh Inventory Glossary, Center for Coastal Resources Management

Enumerated_Domain:

Enumerated_Domain_Value: Grass

Enumerated_Domain_Value_Definition:

Grasslands include large unmanaged fields, managed grasslands adjacent to large estates, agriculture tracts reserved for pasture, and grazing. While a general rule of thumb will classify a tract as “grass” if a home sits behind a large tract of grass, a designation of “residential” may be made if there are similar tracts adjacent to each other. This designation can be determined using best professional judgment.

Enumerated_Domain_Value_Definition_Source:

VIMS Shoreline & Tidal Marsh Inventory Glossary, Center for Coastal Resources Management

Enumerated_Domain:

Enumerated_Domain_Value: Industrial

Enumerated_Domain_Value_Definition:

Industrial operations are larger commercial businesses and can include areas where power plants, pulp mills, refineries, etc. are in operation along the coast.

Enumerated_Domain:

Enumerated_Domain_Value: Paved

Enumerated_Domain_Value_Definition:

Paved areas represent roads which run along the shore and generally are located at the top of the banks. Paved also includes parking areas such as parking at boat landing, or commercial facilities.

Attribute:

Attribute_Label: TREE_FRING

Attribute_Definition:

When the dominant riparian land use is not forested, but a line of trees is maintained along the bank edge, the land use is noted to include a tree fringe. When the tree fringe is between 100 and 500 feet, it is considered a wide tree fringe. When the tree fringe is greater than 500 feet, it would be labled "forested" in land use.

Attribute:

Attribute_Label: SPIT

Attribute_Definition:

A narrow coastal landform tied to the upland shoreline at one end resulting from the deposition of sand moved by tides and currents. Spit features are generally sandy and may be dominated by beach, dune, and/or marsh habitats. For inventory purposes, this definition does not include spit features that are developed or have developable upland.
