World - Ocean Polygons (Natural Earth 10m)

Global land polygon layer at 1:10 million scale from Natural Earth, representing all land areas including major islands. Used as a base map land mask for cartographic production, spatial analysis, and overlay with other global datasets. Use this layer for land/sea masking, continental mapping, and as a reference base for thematic global maps. No additional information provided.

Global coastline boundaries at 1:10 million scale from Natural Earth, representing the boundary between land and sea. Derived from a combination of vector and raster sources and hand-edited for cartographic accuracy. Use this layer as a base map reference for continental and global-scale maps, coastal analysis, maritime boundary studies, and environmental assessments worldwide. No additional information provided.

Global lakes and reservoir polygons at 1:10 million scale from Natural Earth, including major inland water bodies worldwide. Includes the Great Lakes, Lake Victoria, Lake Tanganyika, and all other significant lakes. Use this layer for inland water mapping, hydrological analysis, environmental assessments, and cartographic base mapping globally. No additional information provided.

Global glaciated areas and permanent ice sheets at 1:10 million scale from Natural Earth. Includes major glaciers, ice fields, and permanent snow cover worldwide. Use this layer for climate change monitoring, cryosphere studies, freshwater resource assessments, and cartographic base mapping at global and continental scales. No additional information provided.

Global coral reefs and atolls at 1:10 million scale from Natural Earth. Includes major reef systems and atoll formations worldwide. Africa's coastal reefs along the Indian Ocean and Red Sea are included. Use this layer for marine conservation planning, coastal zone management, fisheries management, and biodiversity assessments in reef ecosystems. No additional information provided.

Global urban area polygons at 1:10 million scale from Natural Earth, representing the extent of built-up areas in cities and towns worldwide. Includes urban extent polygons with population and scale rank attributes. Use this layer for urban growth analysis, population distribution mapping, infrastructure planning, land use analysis, and cartographic base mapping at global and continental scales. No additional information provided.
