World Marine Regions Boundaries

Overview This Feature Service provides detailed polygons representing the major physical marine regions across the globe, including oceans, seas, bays, and other large water bodies. These spatial boundaries offer a comprehensive view of marine regions as defined and attributed by an international team of volunteers, primarily derived from Patterson's Physical Map of the World. Feature Layer World Marine Regions: This layer includes polygons that delineate different marine geographic regions. The data is attributed with fields such as the region's name, scalerank indicating importance or scale, and labels for mapping purposes. These regions are intended to represent physical boundaries at a scale roughly accurate to 50 million scale but detailed to 10 million scale, useful for thematic mapping and marine spatial analysis. Geographic Coverage This dataset provides a global overview, covering all major oceanic and sea regions worldwide, providing context and structure for oceanographic, environmental, and geographic studies. Use Cases Mapping and analysis of marine regions for educational and research purposes. Supporting marine spatial planning and conservation efforts. Providing a base layer for oceanographic and environmental GIS analyses. Source and Licensing The data originates from Natural Earth and is public domain. It can be used freely for personal, educational, and commercial purposes without permission. While boundaries are roughly accurate, users are encouraged to perform map algebra operations with consideration of the scale and the nature of the source data.
