Description:
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.

Attribute_Accuracy:
Attribute_Accuracy_Report:
The Local Drainage Basin Direction layer retains the feature types and information identified by the State of Connecticut, Department of Environmental Protection and obtained from the Major, Regional, Subregional, and Local Drainage Basin Databases.  All attributes have valid values.  Attribute values were either entered manually, and express only general information that doesn't need high accuracy, or were populated through a spatial join; and in that case only as accurate as the attribute data in the table it was joined to.
Logical_Consistency_Report:
Point features conform to the following topological rules. Points are single part. There are no duplicate points. Points do not overlap. Establishment of logical consistency was performed by the State of Connecticut, Department of Environmental Protection using ESRI ArcGIS software to manually create and control feature topology in geodatabase format. No automated procedures or tests were performed to guarantee desired topology other than visual inspection.
Completeness_Report:
The data is complete.  There is at least one Subregional Drainage Basin feature for each Subregional Drainage Basin.

Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The horizontal accuracy of these data meets the intended use.  These data are strictly cartographic.  Point feature locations are near and not exactly at the corresponding outlet locations.

Point Data
Process_Step:
Process_Description:
Feature digitizing and attribution (heads up digitizing method) - Using ESRI ArcGIS software, features appearing on the source map were manually digitized on the screen (heads-up digitizing) at a display scale of 1:80,000 using  Reference Data and Lidar 2000 contours displayed in the background for reference. Reference Data includes 1:24,000 scale roads, waterbodies, political boundaries, geographic names, and geographic place name  information used for background reference purposes. These were used mainly to avoid any conflicting features as these points will be included in maps that contain this information.  Individual features were digitized based on information from the Subregional Drainage Basin database. Features were assigned DIRECTION_ANGLE attribute values based on information from the local basin layer.

Detailed_Description:
Entity_Type:
Entity_Type_Label: Connecticut Subregional Drainage Basin Direction
Entity_Type_Definition:
Basin Outlet location and direction point features show general locations and flow directions of all Subregional Drainage Basins in the State of Connecticut. All points are strictly cartographic and locations of all points were chosen to not conflict with other base map features and your ability to read the map. These point features must be symbolized with arrow-like symbols that depict direction based on the numeric values stored in the field named DIRECTION_ANGLE.

Attribute_Definition:
Subregional Drainage Basin Number - Encodes the Subregional Basin Number for the Direction Point. The Subregional Drainage Basin Number is the first 4 digits of the 13-digit drainage basin identification number (BASIN_NO). The first digit corresponds to the Major basin number (MBAS_NO) and the first 2 digits represent the Regional basin number (RBAS_NO). All Subregional basins in the same Major and Regional basin have the same first and first 2 digits, respectively. A Subregional drainage basin number ending in "00" defines the main-stem basin for the corresponding Regional drainage basin. For example, Subregional basin 4300 is the main-stem basin for Regional basin 43. These main-stem Subregional basins are usually named after the corresponding Regional basin.

Regional Drainage Basin Number - Encodes the Regional Basin Number for the Direction Point.  The Regional Drainage Basin Number is the first 2 digits of the 13-digit drainage basin identification number (BASIN_NO). The first digit corresponds to the Major basin number (MBAS_NO). All Regional basins in the same Major basin have the same first digit. A Regional drainage basin number ending in "0" defines the greater main-stem basin for the corresponding Major drainage basin. For example, Regional basin 40 is the main-stem basin for Major basin 4. These main-stem Regional basins are usually named after the corresponding Major basin.
