Description:
Abstract:
This composite shaded relief image dataset depicts generalized bathymetry and topography of the Caribbean region.
Purpose:
The dataset was created as a means to display shaded relief information in the cartographic products for U.S. Geological Survey Open-File Report 97-470-K, Map Showing Geology, Oil and Gas Fields, and Geologic Provinces of the Caribbean Region. The image is a composite of two individual datasets: 30 arc-second topographic grid data (GTOPO30) and 1- minute bathymetric grid data (GEBCO). The image was considered suitable for this type of display at a scale of 1:2,670,000. It is provided for others who may wish to compile a mapping project in the region.
Supplemental_Information:
The image was created for aesthetic purposes only and should not be used for analysis or navigation. Check the data quality portion of this document before using the image in other projects. Exports between ArcGIS and graphics programs may have degraded original data quality, while georeferencing can affect original horizontal accuracy of data. A smooth gradient technique was used on data to emphasize color and variability of surfaces. Also note that every keyword place name may or may not be noted.

Attribute_Accuracy:
Attribute_Accuracy_Report:
Attributes only convey RGB values of individual cells. No other attributes were added.
Logical_Consistency_Report:
Dataset is a compilation of two published datasets which are also compilations from various sources. Accuracy depends upon the stated accuracies of original data in addition to introduced error from merging processes.
Completeness_Report: Complete
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
No horizontal positional accuracy quantified. Accuracy largely based on original source data. A brief description is provided below.

Original 30 arc-second global topographic (GTOPO30) data accuracy varies by location because sources are chosen on the best available for the area, and use a total of eight sources worldwide. Sources could be raster or vector, with more accuracy claimed from the raster sources. The exact source(s) of the data for the extent shown in the Caribbean region were not determined. Horizontal accuracy is considered to be no greater than the spatial resolution of 1000 meters.

The second dataset is a compilation of bathymetric data provided by the British Oceanographic Data Centre in their General Bathymetric Chart of the Oceans (GEBCO) product. A wide variety of sources and scales were used by the data provider to digitize contours for use in the 1-minute grid product. Horizontal accuracy is considered to be no greater than the spatial resolution of 2000 meters. The graphical merging process, where GEBCO 1-minute data were combined with GTOPO30 topographic data, introduced additional error through exporting to a compressed JPEG image format. The JPEG format uses a lossy compression technique to reduce file size at the sacrifice of image quality.
