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. The last Shoreline Report for Lancaster County was published in 2001.
Purpose: To inventory Virginia's tidal shoreline conditions.
Supplemental_Information:
There are four shapefiles that are part of the 2015 Lancaster County Shoreline Inventory database:Lancaster_lubc_2015, Lancaster_sstru_2015, Lancaster_astru_2015 and Lancaster_tm_2015. Lancaster_lubc_2015 (land use and bank cover for Lancaster County) is a linear shapefile containing data about land use, tree fringe, bank height, bank cover, bank stability and beach status along the shoreline. Lancaster_sstru_2015 (Lancaster Countyshoreline 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). Lancaster_astru_2015 ( Lancaster County access structures) is a point shapefile with locations of docks, dilapidated docks, boathouses, and private and public boat ramps. Lancaster County_tm_2015 (Lancaster County tidal marshes) shows the location, size, species and type of tidal marshes. The attributes of these four shapefiles are explained in the Entity and Attribute Information section below.

Use_Constraints:
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.

Logical_Consistency_Report: Arcs do not overlap.
Completeness_Report:
A new Lancaster County shoreline was generated using the 2013 VBMP imagery as a backdrop and using ArcGis version 10.1. This same imagery as well as Google Earth 2015 imagery was used to code land use attributes. Virginia Lidar was used for bank height coding. All data is subject to Processor interpretation and clarity of imagery used.

Process_Step:
Process_Description:
A shoreline for Lancaster County was created using the 2013 VBMP imagery as a backdrop and using ArcGis version 10.1. Using this as a baseline the shoreline inventory was remotely generated using two sources: Google Earth 2015 imagery , and 2013 high resolution imagery available through Bing Maps and 2013 high resolution imagery available from the Virginia Base Mapping Program (VBMP). The shoreline was coded for land use, bank height, bank condition, bank cover and the presence or absence of beach, access structures and hardened structures.
Process_Date: 20151001
Process_Step:
Process_Description:
All processing steps for the shoreline inventory 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, tree fringe and presence or absence of beach, for the access structure shapefile arcs were coded for dock, dilapidated dock, boathouse, and public and private ramps, 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 and <50 slips.
