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 of the 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 is the first Shoreline Inventory Report for the City of Suffolk. Data collected describes conditions in the immediate riparian zone, the bank, and along the shore.
Purpose: To inventory the City of Suffolk tidal shoreline conditions.
Supplemental_Information:
There are four shapefiles that are part of the 2013 City of Suffolk Shoreline Inventory database: Suffolk_lubc, Suffolk_sstru, Suffolk_astru and Suffolk_tm. Suffolk_lubc (land use and bank cover for the City of Suffolk) is a linear shapefile containing data about land use, tree fringe, canopy overhang, bank height, bank cover, erosion and beach status along the shoreline. Suffolk_sstru (the City of Suffolk 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). Suffolk_astru ( the City of Suffolk access structures) is a point shapefile with locations of docks, dilapidated docks, boathouses, and private and public boat ramps. Suffolk_tm (the City of Suffolk tidal marshes) shows the location, size, species and type of tidal marshes

Attribute_Accuracy_Report:
Assumptions were made that all data used for producing this shapefile were accurate.
Completeness_Report:
This inventory targets 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.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Shoreline attributes recorded with a GPS unit as the boat moves along the shoreline has a horizontal accuracy of +/- 5 meters. Data was transferred from the GPS boat track to an existing digital shoreline coverage by projecting data to the shoreline at a 90 degree angle from the boat track. Rectified imagery were used as a background coverage to aid in data positioning. Land use features were placed along the shore so changes in land use were coincident with changes illustrated in the imagery. Positional accuracy for data that has been corrected with imagery which has a resolution of 2 meters or better. Accuracy limits of the field collected data, however, are set at 5 meters due to the short occupancy of GPS units. In many cases the image correction yields a final positional accuracy much closer to 2 meters or less, depending on image resolution.

Source_Contribution:
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.
Process_Step:
Process_Description:
Wherever possible, all field surveys are performed from a small shoal draft vessel navigating at slow speeds parallel to the shoreline. To the extent possible, surveys take place on a rising tide allowing the boat to be as close to the shore as possible. The field crew consists of a boat operator and one data surveyor. The boat operator navigates the boat to follow the shoreline geometry.
Process_Date: 2013
Process_Step:
Process_Description:
Remote sensing techniques are used in areas where navigation by boat is restricted due to water depth. For these cases, recent high resolution color infra-red and natural color imagery (2009 and 2011) with a resolution of 1 meter or better is used along with Bing oblique imagery to identify and code the shoreline for shoreline attributes. This coding takes place in the ArcMap environment using coding, heads-up digitizing, and photo-interpretation techniques.
Process_Date: 2013
Process_Step:
Process_Description:
For surveyed areas data are logged using a geo-referenced video camera. The Red Hen System provides hardware and software to collect geo-referenced video and photo data in the field. A standard video camera (sony ACC-HDV7) is interfaced with a GPS antennae via the Red Hen hardware device - VMS 300. VMS 300 converts GPS data into audio signals, which are sent to a video camera through its microphone input connector. As the video is recorded, GPS data are transmitted once per second to the video camera by VMS 300. Each GPS location is linked with a time code on the video. Therefore, the survey is a set of videos containing geographically referenced shoreline data.
