Bathymetric Survey Mosaic

Overview This service provides a mosaic dataset of bathymetric raster coverage delivered as an ArcGIS Server image service. It contains single-band floating point depth or elevation values in the AMD raster format, with Bilinear resampling and a geographic extent spanning the globe in WGS 84 (EPSG:4326). The data supports image display, metadata access, and catalog queries. The raster collection is organized with ByAttribute mosaic ordering and LockRaster access, allowing the imagery to be composited from up to 20 images at once. The service includes a large bathymetric value range, with values from about -5811.856 to 0.39. Band Characteristics The service contains 1 band named Band_1. Pixel type: 32-bit floating point Band values: minimum -5811.85595703125, maximum 0.38999998569488525, mean -3429.376005063713, standard deviation 2434.578404080428 Raster Properties Dataset format: AMD Pixel size: approximately 0.081538 Default resampling: Bilinear Compression: None Histograms: available across a range from -5811.85595703125 to 0.38999998569488525 Raster functions: ColorHillshadeBAG, ColorHillshadeBAG_lapaz, ColorHillshadeBAG_rainbow, and None for shaded-relief style visualization Download controls: up to 20 images per download with a 2048 MB size limit Access and analysis: copy, analysis, advanced queries, metadata, catalog access, and image export are supported Mosaic Properties This service is built from a mosaic dataset containing bathymetric raster items. The catalog includes metadata fields for item name, category, tag, group name, product name, center location, pixel size range, z order, survey identifier, and related geometry attributes. The category domain supports values such as Primary, Overview, Uploaded, and Custom. Catalog queries support statistics, ordering, pagination, distinct values, and standardized query expressions, with a maximum record count of 1000. Geographic Coverage The service has global coverage in geographic coordinates with an extent in WGS 84 (EPSG:4326). Use Cases This service supports bathymetric visualization, seafloor depth inspection, catalog review, and raster-based analysis workflows. Users can export images, query catalog records, inspect metadata, and apply shaded-relief rendering for interpretation.
