Abstract:

2007 IRL Seagrass coverage photointerpreted from July 10, 2007, July 13, 2007, August 4, 2007, and January 1, 2008 at a scale of 1:24,000 and August 8, 2007 at a scale of 1:10,000 natural color aerial photography from Ponce Inlet south to the Jupiter Inlet. Features were classified according to SFWMD/SJRWMD modified FLUCCS. The 2007 seagrass Photointerpretation for the project was accomplished on Avineon's ImageStation Stereo Display (ISSD).
Seagrass cover type boundaries were photogrammetrically digitized using CadMap/dgn software in conjunction with ISSD, running on Pentium workstations with Windows 2000. This software directly captures digital data into MicroStation (Bentley Microsystems, Inc.) for later importation to ARC/INFO.
Photointerpreters utilized previously collected field data along with other available collateral data to assist in their interpretation. Throughout the photointerpretation process, positional accuracy of seagrass boundaries was maintained according to the photographic signatures apparent on the photography. The minimum mapping unit for classification is 0.25 acres (=0.1 hectares). The horizontal accuracy of the data meets NMAS for 1:24,000 scale maps (+/- 40 feet). A thematic accuracy assessment was performed on this dataset.

Purpose:

A primary objective of the Indian River Lagoon (IRL) Surface Water Improvement and Management (SWIM) Plan is to protect and restore seagrasses. The IRL SWIM Plan directs the South Florida and St. Johns River Water Management Districts to map seagrasses in the Indian River Lagoon at two to three year intervals. Accordingly, Indian River Lagoon seagrass maps have been prepared for the following years: 1986, 1989, 1992, 1994, 1996, 1999, 2001, 2003 and 2005
These lagoon-wide maps, based on aerial photographs, provide an overall picture of the seagrass resources in the IRL. These maps serve as important management tools for obtaining a current inventory of this resource, identifying "healthy" areas that may deserve special protection efforts, and identifying potential "problem" areas that require further investigation. The maps can also document large-scale trends in the status of this resource.

Attribute_Accuracy:

Attribute_Accuracy_Report:

Attribute accuracy was tested by visual comparison of the aerial photographs with the seagrass data to ensure consistency with the classification system and photo signatures. Pre-interpretation groundtruthing was also performed to aid in delineation and classification of photo signatures. Additional checks for valid attributes, as defined by the SJRWMD/SFWMD modified FLUCCS, were performed. A classification accuracy assessment was conducted 0n 200 random generated points covering the entire lagoon system the resulting accuracy for this project were 89.0%.

Logical_Consistency_Report:

Polygon and chain-node topology present. NODEERRORS run with Dangle option. No dangles present. UNSPLIT used to remove superfluous pseudo-nodes. LABELERRORS run, with all polygons attributed. RELATE was employed to check for contiguous arcs. No arcs have the same attribute on both sides.

Completeness_Report:

Minimum mapping unit for seagrass, algae beds and unvegetated bottom polygons is 0.25 acres. The study area boundary for the project was defined by the SJRWMD. Features were captured and classified according to the minimum mapping unit guideline and the SJRWMD/SFWMD modified FLUCCS.

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Ground controlpoints were provided by the SJRWMD from the 1996, 1999, 2003 and 2005 mapping efforts. These points included both GPS survey points and control points collected from USGS 1m DOQQ's. Horizontal positional accuracy of the data meets NMAS for 1:24000 scale maps, approximately +/- 40 feet. Digital linework was reviewed over USGS DOQQ and the 2005 seagrass data. Well defined features on the images and 2005 data were inspected for comparison to 2007 linework collected representing those features. GPS points were also collected during 2007 seagrass field work at well defined features and compared against coordinates for the same features on the 2005 data.

Process_Step:

Process_Description:

Ground control points were taken from the 2005 mapping effort and 10 additional points were collected in the field during the 2007 mapping effort. The points were imported from 2005 IRL seagrass project. The 2005 ground control points provided the latitude and longitude coordinates for each point. These items were referenced to identify and transfer the points to the 2007 aerial photo layout. In 2007 Avineon had collected several new control points from USGS DOQQ's to densify the control network, filling in the gaps where necessary. The pixel coordinate values, which are embedded within the digital orthophotographic imagery, were collected for photoidentifiable features on the DOQQ image.
The values for the points provided from the 2005 project were expressed as geographic coordinates (latitude/longitude), NAD83, HARN Feet. The values for the points collected from DOQ were expressed in UTM coordinates, NA83, HARN Meters. All coordinates were transformed; using a conversion program called Corpscon, to Stateplane coordinates, NAD83, HARN Feet.
