Benthic Habitat Mapping Data

Data Data Description
Original Imagery

Orthophoto Description:
Orthorectified aerial photo collected using a Leica ADS40 sensor.  The image was collected by the USACE, and is in GeoTIFF format (.tif). 

Bathymetry (LiDAR) Description:
Image describing the depth (bathymetry) of the seafloor collected using Light Detection and Ranging (LiDAR).  The image was collected by Tenix LADS, and is in GeoTIFF format (.tif). 

 Bathymetry, Backscatter & Morphometrics (SoNAR) Description:
Images describing the depth (bathymetry), physical properties (backscatter) and vertical complexity (morphometrics) of the seafloor collected using Sound Navigation and Ranging (SoNAR).  The images were collected and processed by USGS and NOAA, and are in GeoTIFF format (.tif).

 
Source Imagery

Water Column Corrected Orthophotos Description:
Orthorectified aerial photos radiometrically corrected for changing water column conditions. These images are in GeoTIFF format (.tif).  They were used to identify, delineate and classify shallow-water benthic habitats inside BIRNM.

Relative Reflectivity (LiDAR) Description:
Image denoting the relative reflectivity of the seafloor collected using LiDAR. This image is in GeoTIFF (.tif) format, and was used as an ancillary dataset to identify, delineate and classify shallow-water benthic habitats inside BIRNM.

Principal Component Surfaces (SoNAR) Description:
Images describing the vertical complexity of the seafloor derived from the morphometric surfaces. These images are in GeoTIFF (.tif) format, and were used to identify, delineate and classify shallow, moderate and deep-water benthic habitats inside BIRNM.

Benthic Habitat Maps

Benthic Habitat Maps Description:
ESRI shapefiles representing the shallow, moderate and deep-water benthic habitats mapped inside BIRNM.

Ground Validation (GV) Sites

GV Sites Description:
ESRI shapefiles denoting the location of underwater photos and videos collected to produce the BIRNM benthic habitat maps.

Accuracy Assessment (AA) Sites

AA Sites Description:
ESRI shapefiles denoting the location of underwater photos and videos collected to evaluate the thematic accuracy of the BIRNM shallow-water benthic habitat map.
