mlclass5 - Nahant to Gloucester, Maximum Likelihood Bottom Classification
Entry ID: CZM_moris_mlclass5_raster


Summary
Abstract: These data are high-resolution maximum likelihood classification of the seafloor offshore of Massachusetts, from Nahant to Gloucester. Approximately 127 km? of the inner shelf were mapped in the nearshore region between the 10m and 40-m isobath.

Purpose: The purpose of this data set is to calculate a generalized sea floor bottom type using multivariate statistics, and high resolution depth (bathymetry) and acoustic backscatter (sidescan sonar) data. These data were collected under a cooperative agreement with the Massachusetts Office of Coastal Zone Management (CZM) and the U.S. Geological Survey, Coastal and Marine Geology Program, Woods Hole ...

Quality LOGICAL CONSISTENCY REPORT: Bottom classification was calculated using the ISOCluster and Maximum likelihood tools combined in a custom modelbuilder model. Rigorous error analysis of the ISOCluster function has not been conducted. These data are intended for regional geologic framework investigations and should not be used for applications at fine scales without additional ground validation

Use Constraints USE CONSTRAINTS: Data are not intended for navigational use. These data should not be used at resolutions for which they are not intended. Additional ground validation should be conducted to use these data for applications other than regional geologic framework studies at spatial scales finer that 1:60,000. Public domain data from the U.S. Government are freely redistributable with proper metadata and source attribution.
