Abstract:
The U.S. Environmental Protection Agency's (EPA) Reach Files are a series of hydrographic databases of the surface waters of the continental United States and Hawaii. A key characteristic of the Reach files are their attributes that define the connected stream network. These attributes provide connectivity regardless of the presence or absence of topologic continuity in the digital linework. Flow direction is inherent in the connectivity attributes. This attribute-level connectivity enables the Reach Files to provide hydrologic ordering of stream locations using reach codes (what is upstream and downstream of a given point in the stream network) as well as network navigation proceeding in either the upstream or downstream direction.

RF3-Alpha data is un-validated and given the nature of the shortcomings that have been identified in the RF3-Alpha data and the re-design work that is being incorporated into RF3 validation to support GIS applications, it is recommended that a conservative approach be taken when processing and applying these data. The final, validated RF3 ("The National Hydrography Dataset") will provide a much improved data product. In the mean time, access to the provisional Alpha data, accompanying documentation, and technical support is provided through the Office of Water's (OW) STORET User Assistance Group. STORET, EPA's national water quality data system, is currently undergoing a major re-design to address evolving user requirements and technology advancements including GIS. Both STORET and RF3 will play integral roles in EPA's future water quality data collection, analysis, and reporting activities.

For further assistance on RF3 Alpha, please contact STORET User Assistance at 800-424-9067.

Purpose:
The structure and content of the Reach File databases were created expressly to establish hydrologic ordering, to perform hydrologic navigation for modeling applications, and to provide a unique identifier for each surface water feature, i.e., reach codes.
Supplemental_Information:
Procedures_Used: RF3a files were initially produced as ArcInfo export files (.e00 file) on a U.S. EPA mainframe computer in the STORET environment. RF3a vector files were requested by hydrological unit code (HUC) within an entire state. Upon completion of mainframe processing, the RF3a files were downloaded using file transfer protocol (FTP).

The initial processing step involved importing the .e00 file into ArcInfo and projecting it to Albers meters. The projected coverage then had a Length_m (meters) item added with its value calculated to hold the length of the arc in meters after projecting to decimal degrees. The coverage was then projected from Albers-meters to decimal degrees-NAD83. A route feature was then built on the rf3rchid item.

The processed ArcInfo export files were compressed and copied to a PC hard disk for storage in one nationwide directory. Upon completion of processing all of the HUCs, a list was generated of all of the processed files. This list was then compared to a list of HUCs created from the United States Geological Survey's (USGS) 1:250,000 Hydrologic units maps of the Conterminous United States to verify the presence of RF3a files for each HUC.

RF3a files were distributed on for inclusion with the BASINS application on CD-ROM as a series of ArcInfo coverages that included the spatial extent of each of the nine U.S. EPA Regions (including the HUCs that crossed Region boundaries). The nine regional coverages therefore overlapped at Regional boundaries. The coverages were distributed in ArcIno coverage format.

Revisions: With the release of Basins version 2, the RF3 Arcinfo coverages were convertted into Arcview shapefiles.

Reviews_Applied_to_Data: Each HUC coverage was reviewed for quality through an ArcInfo AML. The QA/QC AML performed a variety of checks to validate the processing of the RF3a files. Included in these checks were the following steps:

- Does the rf3a.ds3 info table exist? - Does the rf3a.ds3 info table contain records? - Is the projection set to GEOGRAPHIC? - Are units in decimal degrees? - Is the datum NAD83? - Does the RF3a route feature exist? - Does the RF3a.AAT exist?

Once the QA/QC AML was run on each RF3a coverage, each EPA Region was examined in ArcView. The examination consisted of adding each RF3a line coverage as a theme, looking for spikes in the data, and looking for holes in the data.

Quantitative_Attribute_Accuracy_Assessment:
Attribute_Accuracy_Explanation:
Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modelling purposes. Please be sure you are using the best available data. 1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries.

1:100000 scale datasets are recommended for projects that are at the multi-county or regional level. 1:125000 scale datasets are recommended for projects that are at the regional or state level or larger.

Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analysis. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation. These data are based on interpretation of available information and should not be construed as legally binding.

Logical_Consistency_Report:
Certain node/geometry and topology (GT)-polygon/chain relationships are collected or generated to satisfy topological requirements. Some of these requirements include: chains must begin and end at nodes, chains must connect to each other at nodes, chains do not extend through nodes, left and right GT-polygons are defined for each chain element and are consistent throughout the transfer, and the chains representing the limits of the file (neatline) are free of gaps. The neatline is generated by connecting the four corners of the digital file, as established during initialization of the digital file. All data outside the enclosed region are ignored and all data crossing these geographically straight lines are clipped at the neatline. (Exception: During the QA/QC process all data is examined and if errors are found and corrections are possible, then data is corrected accordingly. This process is documented in the Process_Step.) Data within a specified tolerance of the neatline are snapped to the neatline. Neatline straightening aligns the digitized edges of the digital data with the generated neatline, that is, with the longitude/latitude lines in geographic coordinates. All internal polygons are tested for closure. Certain attributes and/or entities, e.g. closure line, convey data quality information. When information to be encoded in the subfield is known to be not applicable (undefined, not relevant), then the subfield is valued by a string of "9s"; and when the information to be encoded is relevant but unknown (or missing), then the subfield is valued by a string of "9s."
