Title: Oyster Habitats Sebastian River Florida 2006

Geospatial_Data_Presentation_Form: vector digital data

Description:

Abstract:

This polygon GIS data set represents the location and coverage area of most major oyster reefs within the Sebastian River. Each oyster reef was mapped using Real-Time Kinematic GPS (RTK GPS). Transect surveys were conducted at 1-m intervals across the face of the reef, perpendicular to the long-axis of the reef and extending from border to border. The latitude, longitude and height (elevation) data for each 1-m interval were collected using the RTK GPS rover unit. No data points were taken outside the perimeter of the reef. These data points were used to create a perimeter polygon for each reef to delineate its location and surface area.

Purpose:

Conduct updated mapping of the major oyster reefs and provide a quantitative summary of oyster reef distribution patterns in the Sebastian River as a baseline for comparison with future mapping efforts.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

To assure accurate oyster biological data (percent of live oysters, height of live and relic oysters, and number of live and relic oyster/m2) in the attribute table, two different data recorders proofed all records.

Logical_Consistency_Report: polygon values fall within an acceptable range

Completeness_Report: Information is complete for the study area

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Horizontal positional accuracy for the shapefile is tested by visual comparison of the source with on-screen existing data sets and aerial photos.

Process_Step:

Process_Description:

To increase the accuracy of our horizontal and vertical data, the RTK GPS base-station was used as a temporary benchmark for each day's survey. The base station was set to record its position every 10 seconds for a minimum of 2 hours. This temporary benchmark data was later submitted to the National Geodetic Survey's On-line Positioning User Service (OPUS) for post-processing. For all applications, the portable RTK GPS rover unit used to acquire geographic coordinates was set with a Position Dilution of Precision (PDOP) value of six or less to maximize the accuracy of our positional data, and the number of satellites used was set at a minimum of six to ensure that PDOP cap. Satellites below 15o above the horizon were not included, and the minimum signal-to-noise ratio was set at 6.0

Transect surveys were conducted at 1-m intervals across the face of the reef, perpendicular to the long-axis of the reef and extending from border to border. The latitude, longitude and height (elevation) data for each 1-m interval were collected using Real-Time Kinematic GPS (RTK GPS). No data points were taken outside the perimeter of the reef. From this data, polygons were created which represent the outside perimeter of the oyster reef.
