Description:

Abstract:

This project is a cooperative effort between the National Ocean Service, National Centers for Coastal Ocean Science, Center for Coastal Monitoring and Assessment, the state of Florida and Analytical Laboratories of Hawaii, LLC. The goal of the work is to use NOAA-developed mapping methods to produce benthic habitat maps of southern Florida. The maps are generated by photo interpreting georeferenced IKONOS satellite imagery. These underwater video and still images are collected to perform ground validation of seafloor habitat features during map preparation.

Purpose:

The National Ocean Service is conducting research to digitally map biotic resources and coordinate a long-term monitoring program that can detect and predict change in U.S. coral reefs, and their associated habitats and biological communities. The purpose of this survey was to investigate areas of imagery where uncertainties exist on the photo interpreter's behalf during the decision making process of benthic habitat type for southern Florida.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

The GPS points in this thematic data layer were acquired by GPS data using a Trimble GeoExplorer 3 with a customized data dictionary designed to reflect the NOAA Classification Scheme for Benthic Habitats of the southern Florida. All habitat determinations were made in the field, recorded in the GPS data logger and seamlessly transferred to ArcView GIS using Trimble Path Finder Office Software. Attributes are all expected to be correct.

Logical_Consistency_Report:

The sites for collecting underwater video and still imagery for ground validation were selected to specifically investigate habitat types and gradients of habitat spectral signatures and spatial extent. All areas where uncertainty existed on the part of the photo interpreter during habitat delineation were investigated in the field. Waypoints in these habitats areas were generated on the georeferenced imagery using a GIS. The waypoints were then loaded into a GPS and, using a boat, were navigated to. Underwater video or still imagery and exact GPS positioning were obtained. For GPS positioning, one hundred GPS positions were collected at one-second intervals. The 100 positions were averaged to obtain a single survey point. The data were post processed for differential correction. The general area was explored and, as needed, additional underwater or still imagery and GPS positions were collected to mark transitions between habitat types of areas mapped at the level of the minimum mapping unit (MMU). These data are believed to be consistent.

Completeness_Report:

Several hundred ground validation field positions were occupied and habitat characterization conducted for ground validation during this work. These data were included in the dataset as a GIS layer and the first draft map was edited based on this ground truth. All areas where uncertainty existed on the part of the photo interpreter during habitat delineation were investigated in the field. All data were collected and integrated into the mapped products as planned.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Point accuracy was determined by three tests producing circular RMS statistic. Point GPS data were acquired by repeated occupation of a fixed point yielding a 95% sigma RMS of 5 meters compared to the position mean. Replicate GPS positions were collected after navigating to a way point by boat yielding RMS value of 5 meters. Registered monuments were occupied and replicate positions collected yielding an RMS value of 3 meters. Thus, all point features in these ground validation data are at least 95% sigma of 5 meters.

Process_Step:

Process_Description:

The first draft of each benthic habitat map was generated by visual interpretation of the habitat boundaries from remote sensing imagery, and areas where habitat determination was uncertain were identified. Waypoints in these areas were generated on the geo-referenced imagery and over laid on the draft maps in the GIS. The areas were printed and water proofed in preparation for taking them into the field. The waypoints were navigated to and occupied using the appropriate size boats. The habitat was observed and GPS data collected. One hundred GPS positions were collected at one-second intervals for each survey site. The positions were averaged to obtain a single survey point. The data were post processed for differential correction to the nearest CORS. The general area was explored and, as needed, additional GPS positions were collected to mark transitions between habitat types of areas mapped at the level of the minimum mapping unit (MMU). The underwater video or still imagery ground validation data were overlaid on the imagery with the first draft habitat map in the GIS. The habitat polygons were edited to resolve uncertainties. These ground validation point data are provided in this thematic GIS shape file.
