- Abstract:
-
Bathymetric data derived from a multispectral World View-2 satellite
image mosaiced to provide near complete coverage of nearshore
terrain around the islands. Bathymetry values shallower than ~20 m were
derived by gauging the relative attenuation of coastal, blue, green and yellow
spectral radiance as a function of depth. A multiple linear regression analysis
of coastal, blue, green and yellow band spectral values against depth determined
the variables of y-intercept, coastal,blue, green and yellow slope values.
Variables then used in multivariate slope intercept formula to derive
depth. Variables were adjusted to improve the statistical accuracy and
spatial coverage of the final derived bathymetry product. Digital image
processing to derive depths conducted with the ENVI 4.8 software program
while data editing and integration was performed using ArcGIS 10. This
data set is for the shelf environment of Agrihan Island, Mariana.
- Purpose:
-
The data were derived in support of NOAA Coral Reef Conservation
Program goals. Goal 1 is to map all U.S. Coral Reef Ecosystems.
This data set specifically addresses Objective 1 and 4: to develop
high-resolution benthic maps and to characterize priority deep
water reefs and associated habitats. This derived bathymetry provides a
GIS layer with expanded spatial coverage that may be used for benthic and
essential fish habitat characterization, and for the study of geologic features.
By combining the dataset with other bathymetry, backscatter, derivatives,
and in situ data, they collectively compose benthic habitat maps
designed to be used to understand and predict shallow depth (0m to 150m)
benthic habitats for organisms that inhabit coral reef ecosystems.

Multiple tools in ENVI 4.8 were used to complete the following
processing steps: Data conversion from digital number to radiance,
correction for atmosphere and water surface reflection, masking of
non-applicable values, and bathymetric derivation using variables
from multiple linear regression analysis. Multiple tools in
ArcGIS 9.3 were used for dataset integration and to extract values
for the multiple linear regression analysis and subsequent error
analyses. The Microsoft program Excel was used for the multiple
linear regression analysis to provide original variables for depth
derivation. The multivariate slope intercept formula used to
derive depth was Depth=Yint+(Mcoastal)(Xcoastal)+(Mblue)(Xblue)+
(Mgreen)(Xgreen)+(Myellow)(XYellow).Two products were derived,
from the original images 11DEC24012757-M2AS-053850193010_01_P005
and 12MAY03010521-M2AS-053850193010_01_P007.The MLR variables for
image 11DEC24012757-M2AS-053850193010_01_P005 were Yint=48.6730490,
Mcoastal=-1.278749828, Mblue=-0.443251739, Mgreen=2.078005407,
Myellow=-0.391474601 which was used for the West Shore, for image
12MAY03010521-M2AS-053850193010_01_P007 were Yint=-1.991017711,
coastal=-0.471700952, Mblue=-0.383778197, Mgreen=1.591490893,
Myellow=-0.220491633 which was used for East, North and South Shore.
The derived bathymetry from each image were in turn mosaiced
giving the data from 11DEC24012757-M2AS-053850193010_01_P005 priority
over 12MAY03010521-M2AS-053850193010_01_P007 in overlapping areas due to
its statistically higher accuracy.
A detailed description of all processing steps and an error analysis of
each derived bathymetry grid used is available upon request.
