This classification of estimated depth represents the relative bathymetry of the U.S. Virgin Islands shallow waters based on Landsat imagery for NOAA's Coastal Centers for Monitoring and Assessment (CCMA). This data supports mapping and research activities of NOAA NOS. These data were created for the NOS Summit-to-Sea project. This project determines relationships between terrestrial and bethic change. The data were created using NOS developed algorithms. Bathymetry was derived from six Landsat images of different dates for the USVI. The final bathymetry layer was derived from a per pixel median analysis of th 6 bathymetric layers. The results were verified using field collected depth supplied by NOAA. Depths are only reported within the shallow environment as determined by maximum penetration of band 1 (blue) of Landsat TM.

No formal attribute accuracy report was implemented. However ground truthing data and NOAA nautical charts were used for verification. Post-Processing Steps: None Known Problems: None Spatial Filters: None
Total RMS for horizontal accuracy ranged from 12.6987 to 46.1257.
There was no terrain correction in the geo-referencing procedure.
Data are complete
Checked for zeros in background and made sure all georefrencing was correct.

Imported raw data AOI subsets into IMAGINE format from binary. Selected the best, least cloudy image sample for that path/row. We then ran a water reflectance formula (Bi-B4 or Bi-B5, where i= bands 1-3. This transform compensates for sun glint and water surface albedo) through IMAGINE. Once the water reflectance was available the log ratio method of bands 1 and 2 (m1*100*Log(B1-rdeepB1)/Log(B2-rdeepB2)-m0+0.5 where m1=slope and m0=shift) was applied by adjusting variables of slope and shift until the data reflected the field collected depths provided by NOS.
