ARC/INFO point coverage of river miles of the main channels of Upper Mississippi/Missouri River Citation_Information: Originator: Scientific Assessment and Strategy Team (SAST) Publication_Date: 19950501 Title: RIVER_MILE ARC/INFO Coverage Geospatial_Data_Presentation_Form: map Online_Linkage: http://edcwww.cr.usgs.gov/sast-home.html Description: The SAST ARC/INFO database is a comprehensive vector basemap of the Upper Mississippi/Missouri River Basin and contains attribute data suitable for performing a wide range of analyses and for generating thematic maps for counties and states throughout the flood area. Abstract: On January 10, 1994, the Scientific Assessment and Strategy Team (SAST) joined in the effort to provide scientific advice and assistance to officials responsible for making decisions with respect to the flood recovery in the Upper Mississippi River Basin. This data cover provides river-mile markers and estimates of water elevations for the 10, 50, 100, and 500 year flood events for the mainstreams of the Mississippi and Missouri Rivers. The cover also includes 1993 flood levels by river mile. This data set was created from a point coverage provided to the SAST from the Environmental Management Technical Center (EMTC) and ancillary data from the U.S. Army Corps of Engineers. The area includes the Upper Mississippi, Missouri, Illinois, Minnesota, and St. Croix Rivers. Generally, one point is displayed at one river mile, however, some points on the Missouri River has points every tenth of a mile. Several missing points were amended from data received by the US Army Corp of Engineers(Rock Island). When the data was compared to the 1:100,000 scale Digital Line Graph (DLG)hydrology layer many of the points were off the river Locations for about 700 points, mostly on the Missouri. These points were adjusted by the EROS Data Center to conform to the 1:100,000 DLG locations. Purpose: The objectives in SAST were to develop a database of readily available data to support map production, scientific analysis, and decision making; to produce maps showing base information and vulnerability to flooding; and to prepare reports documenting the products of SAST and the methodology and analysis used to produce them, and identifying the ongoing monitoring, research, modeling, data management and distribution requirements needed to support integrated river basin management. This data set has been plotted with various data layers to better identify locations along the respective rivers. River-mile locations have also been used to identify approximate locations for wildlife species and structures built along the river.

Data_Quality_Information:

During ARC/INFO coverage development several modifications were made to the source data in order to generate a database with a common scale, uniform level of resolution, consistent coding scheme, and comparable (standardized) measurement data. Attribute_Accuracy: Attribute_Accuracy_Report: When the river mile points were shifted the location was tagged with LAT_OLD and LONG_OLD. The relocated points are now attribute items LAT and LONG. Attribute_Accuracy_Explanation: River mile data was tagged with attributes related to pool and flood elevations. These data were derived from channel maps. The values were estimated from the maps to the nearest foot, typed into a file, and then joined with the coverage. Attribute accuracy is described, where present, with each attribute defined in the Entity and Attribute Section. Logical_Consistency_Report: River mile locations were compared against 1:100,000 Digital Line Graph linework with differences up to 2 miles. Approximately 700 points, mostly along the Missouri, were adjusted by EROS Data Center in order to get the river mile points to fall inside the 1:100,000 hydro channel. Completeness_Report: Data completeness reflects the content of the data received on the floppy from the US Army Corp of Engineers. Since there were gaps along the Missouri two other covers containing river mile data were incorporated to fill in these missing points. Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The accuracy of the database components, specifically the latitude and longitude, that originated from the US Army Corps of Engineers and the Environmental Management Technical Center will reflect on the accuracy of this data set. The accuracy of the relocated points by EROS is based on the accuracy of the 1:100,000 DLG and placement to the new locations within the channel. Lineage: Source_Information: This coverage was derived from a point coverage supplied by the Environmental Management Technical Center. Missing points were appended by data from US Army Corps of Engineers and relocation of inaccurate points performed by the EROS Data Center.

Source_Scale_Denominator: 100,000 Type_of_Source_Media: digital files Originator: U.S. Geological Survey Process_Step: Process_Description: The SAST acquired the river mile point data from the Environmental Management Technical Center. The point cover was received on floppy and downloaded to the SAST data base. The other files that were received from the Corps of Engineers contained river miles on the Missouri River with one point every tenth of a mile. These two covers from the COE were used to fill in gaps. This revised cover was used for the shifting of points along the Missouri River. Locations of approximately 700 points, mostly along the Missouri, were found to have discrepancies by comparing locations against the 1:100,000 Digital Line Graph linework (up to 2 miles differences). EROS shifted these points to fall at good locations inside the 1:100,000 hydro channel. In a separate effort, river elevation graphs were read, and tables of elevations were keyed in for each river-mile. The elevation estimates for the flood levels were derived from COE River Navigation Maps. Values were taken from the maps to the nearest foot, and typed into a file, which was ultimately joined with the coverage. The ARC command BUILD was used to recreate coverage topology. BUILD creates or updates a feature attribute table for a coverage. Point features and their attributes are created with the POINT option. Process_Date: In 1994 the river mile data were appended into an ARC/INFO coverage.
