A characterization of the data, including its intended use and limitations.
Abstract: Subregional Drainage Basin Direction is point data used to create directional arrow symbology that depicts the general direction of surface water flow within individual subregional drainage basins. Particular emphasis is given to directional arrows near the location of subregional drainage basin outlets. These aid in the visualizing the network of subregional drainage basins in Connecticut. Point features include an attribute that defines arrow direction. Data is compiled at 1:80,000 scale. Data is intended to be used from 1:200,000 to 1:80,000 scale and should only be used for cartographic purposes on maps that also depict Subregional Drainage Basin Boundaries.
Purpose: Subregional Drainage Basin Direction is a cartographic data product. These point feature must be used with Subregional Drainage Basin polygon and line feature data. They must not be depicted on maps as simple point symbols without symbolizing them with arrows that take on the appropriate direction. Use the DIRECTION_ANGLE attribute to orient the features on the map. It is meaningless to use these data without also including local basin boundaries on a map.
These data do not represent the exact location of basin outlets or stream confluences. Their position is largely based on the need to locate an arrow symbol near each local basin outlet such that it does not interfere or conflict with the placement of other information typically included on a basin map such as highways, local roads, bridges, waterbodies, political boundaries and geographic names. For this reason, some features may be farther away from the basin outlet than others. This information is not intended to accurately represent the hydrologic connectivity of surface water and were not automatically derived from or based on a hydrologic network such as the U.S. Geological Survey National Hydrography Dataset.
Supplemental information: Refer to the metadata for Local Drainage Basin polygon and line feature classes for additional information on the delineation and use of local drainage basin boundaries.
