Title:
An Ecological Characterization of Salt River Bay National Historic Park and Ecological Preserve
Edition: 1
Geospatial_Data_Presentation_Form: document
Description:
Abstract:
Habitat maps were created as part of a larger ecological assessment conducted by NOAA's National Ocean Service (NOS), Biogeography Program, for Salt River Bay National Historic Park and Ecological Preserve (National Park Service). Aerial photographs were obtained for 1988 from the National Geodetic Survey, and were orthorectified by the Biogeography Program. A classification scheme was set up with 20 benthic habitat types, 19 land cover types, and 13 mangrove habitat types. For this map of seagrass and mangrove habitats during 1988 only the 3 seagrass, and 14 mangrove classification categories were used. These were mapped directly into a GIS system through visual interpretation of orthorectified aerial photographs.
Purpose:
These maps were created to support current and future monitoring and management efforts of the National Park Service (NPS) for this site, and support the programmatic objectives of the NPS service-wide Inventory and Monitoring Program. In particular, maps created from the time series of the photographs cover periods both before and after Hurricane Hugo (1989), providing insight to habitat changes that occurred following the disaster.

Attribute_Accuracy_Report:
Methods used to create this map were similar to those used to maps of the U.S. Virgin Islands and Puerto Rico by the same office ("Benthic Habitat Maps of Puerto Rico and the U.S. Virgin Islands", 2001). An accuracy assessment conducted for the original maps was designed to determine the accuracy of maps generated from on-screen digitizing using the ArcView Habitat Digitizer Extension. Benthic habitat maps exhibited an overall accuracy of 93.6 percent (Kappa 0.90-0.93) for on-screen digitizing.

In comparison, the map described here was created from higher resolution imagery (25 microns), finer minimum mapping unit (MMU) (100 square meters), and habitat delineation occurred at a smaller image scale (1:1500). A greater number of ground truth points over more habitat types were verified for the year 2000 mapping data, in a study site of much smaller area. Ground truth points could not be taken directly for the 1988 data, however, year 2000 points were referenced when appropriate. Mapping methods were otherwise the identical to those used previously. Attribute accuracy was therefore presumed to be equivalent to or better than that of the previous map, although an assessment was not conducted on the current map directly.

Logical_Consistency_Report:
Individual color aerial photographs from 1988 were georeferenced and mosaiced. Approximately 10-15 ground control points were used to orthorectify the mosaic. During the digitizing process, image stretches and manipulating image contrast, brightness and color balance were performed in the ArcView Image Analysis Extension to enhance features in the processed imagery. Additional, collateral information including previously completed habitat maps, NOS nautical charts, and other descriptive references dealing with benthic and coastal habitats of St. Croix were used to assist with image interpretation. Over 200 ground truth points were also checked with year 2000 imagery to verify photographic signature with habitat interpretation. Though 1988 habitats could not be directly verified in the same fashion, where appropriate, collateral information from the year 2000 points was considered during 1988 habitat deliniation.

GIS topologic quality was established by executing ArcView extension routines that check for: overlapping polygons, multipart polygons, sliver polygons and void polygons. Additionally, checks for adjacent polygons with the same habitat attributes were completed. All errors were identified and corrected. This file is believed to be logically consistent.

Completeness_Report:
Delineation of all habitat boundaries was conducted with the image scale at 1:1500. All polygons were digitized at this scale except when subtle habitat boundaries were not easily discernable at 1:1500 and zooming out to a more broad scale was required to place boundaries correctly. Digitizing at a uniform scale ensures that the level of detail produced by the photointerpreter is consistent throughout the project.

The Minimum Mapping Unit (MMU) for identifying habitats or features was 100 square meters for visual photointerpretation. The software utilized in this project was designed to alert the photointerpreter each time a polygon was drawn smaller than the MMU. When this occurred, the photointerpreter has the choice of weather to include the polygon in the dataset or not.

Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The Minimum Mapping Unit (MMU) restriction was set to 100 square meters and digitizing was conducted at 1:1500 scale. Polygons were digitized directly from georegistered orthophotos with spatial accuracy approximately 1.0 meter. These maps represent conditions at the time the aerial photographs were obtained. When considering horizontal map accuracy, it is important to keep in mind that the ocean floor is a dynamic environment. Physical factors such as currents, erosion, and hurricanes and biological factors such as seasonal growth and die-off, affect the distribution and stability of terrestrial, mangrove and benthic habitats in this environment.

This project is a cooperative effort between the National Ocean Service, National Centers for Coastal Ocean Science, Center for Coastal Monitoring and Assessment, the United States Geological Survey, the National Park Service, and the National Geophysical Data Center, to produce benthic habitat maps and georeferenced imagery for Puerto Rico and the U.S. Virgin Islands. This project was conducted in support of the U.S. Coral Reef Task Force.

Twenty-one distinct benthic habitat types within eight zones were mapped directly into a GIS system using visual interpretation of orthorectified aerial photographs. Benthic features were mapped that covered an area of 1600 km^2. In all, 49 km^2 of unconsolidated sediment, 721 km^2 of submerged vegetation, 73 km^2 of mangroves, and 756 km^2 of coral reef and colonized hardbottom were mapped.

Process_Step:
Process_Description:
Benthic habitat maps were digitized by delineating habitat boundaries from georeferenced imagery loaded into ArcView 3.2 GIS software with the Image Analysis extension and NOAA Coral Reef Habitat Digitizing extensions both activated. On-screen digitizing was conducted with the minimum mapping unit (MMU) set to 100 square meters and the image scale at 1:1500.

During the digitizing process, image stretches and manipulation of image contrast, brightness and color balance were performed in the ArcView Image Analysis Extension to enhance features in the processed imagery. Additional collateral information, including previously completed habitat maps, NOS nautical charts, and other descriptive references dealing with benthic and coastal habitats of Salt River National Historic Park and Ecological Preserve was used to assist with image interpretation.

A first draft map was completed and features in the imagery where uncertainties existed, due to confusing or difficult to interpret signatures, were identified for future ground validation effort. Since maps where based on historical imagery that didn't necessarily reflect current ground condition, similar signatures were identified in year 2000 aerial photographs. An ArcView GIS point theme was generated with points positioned on the features of uncertain habitat type or along transects through gradients between habitat types. The GIS points were converted to GPS waypoints, and were visited for on the ground habitat validation.

Benthic habitat characterization was conducted at each site by snorkeling, free diving, or via observations from the surface where water depth and clarity permitted. Mangrove habitat characterization was conducted by driving, kayaking or hiking to points and visually identifying mangrove type and cover. GPS data was collected at each location, and site ID, depth, habitat type, and the method used to make the assessment were recorded. The ground validation data was incorporated into the second draft of each map.
