geographic area |
A geographic location, generally having definite boundaries. Note that this differs from its immediate superclass Region in that a GeographicArea is a three-dimensional Region of the earth. Accordingly, all astronomical objects other than earth and all one-dimensional and two-dimensional Regions are not classed under GeographicArea.

anchorage | Anchorage is the subclass of WaterAreas where WaterVehicle may anchor with some shelter or safety. Anchorages may be inside a Harbor or offshore. |
| | body of water | A BodyOfWater is a connected body of water with established boundaries marked by either geographical features or conventional borders. |
| | fresh water area | A WaterArea whose Water is not saline, e.g. most rivers and lakes. |
| | harbor | Harbor is the subclass of WaterAreas that provide shelter and anchorage for WaterVehicle. |
| | hydropower water area | HydropowerWaterArea is the class of WaterAreas with waterflow strength adequate for the production of hydropower. |
| | inland water system | An instance of InlandWaterSystem comprises two or more lakes or rivers, canals, or other waterways that are interconnected. |
| | Nino region | NinoRegion is a class of predefined regions located in the tropical PacificOcean where their seaSurfaceTemperature are moniotred to track the onset at various phases of the ElNinoSouthernOscillation. The numbers of the Niño 1,2,3, and 4 regions correspond with the labels assigned to ship tracks that crossed these regions. Data from these tracks enabled the historic records of El Niño to be carried back in time to 1949. [US National Science Foundation, National Center For Atomspheric Research] |
| | river mouth | RiverMouth is the subclass of WaterAreas that are the outfalls of a river or stream into another body of water. |
| | river system | A RiverSystem comprises all the tributary streams and rivers (StreamWaterAreas) that drain along converging paths into the main river of the system, which discharges into a StaticWaterArea. |
| | salt water area | A WaterArea whose Water is saline, e.g. oceans and seas. |
| | ship berth | ShipBerth is the class of areas where a Ship may be moored, whether at an Anchorage or dock. |
| | static water area | A WaterArea in which water does not flow constantly or in the same direction, e.g. most lakes and ponds. |
| | stream water area | A relatively narrow WaterArea where the water flows constantly and in the same direction, e.g. a river, a stream, etc. |
| | stream water confluence | A StreamWaterConfluence is the place where a stream or other tributary joins a river. |
| | surf zone | The WaterArea off the Shoreline where waves break. |
| | water current | WaterCurrent is a subclass of FlowRegions consisting of moving water, especially those currents found within a well_identified area and having an established pattern of movement, such as an OceanCurrent, a RipTide, or a River. WaterCurrent is disjoint with StaticWaterArea. As a consequence, Lakes for example cannot be FlowRegions, however, currents may be present in a lake. |
| | waterway | Waterway is the class of navigable waters, including Oceans, SeaLanes, Rivers, Canals, Lakes, and inland bodies of water. |
