Digital Geospatial Metadata Report Date: 13-Sep-1996 Data Set Name: 1989 Upper Mississippi River Land Cover/Use 1 Identification Information 1.1 Citation Information: 8.1 Orginator: State GIS Service Center 8.2 Publication Date: Unknown 8.4 Title: Public Land Survey 100K 1.2.1 Abstract: Land cover/use databases were developed from 1989 color infrared aerial photography for pools within the Upper Mississippi River System. Photos were interpreted, and line work was transferred to mylar overlays registered to USGS 7.5' quadrangle enlargements at a scale of 1:15,000 before being manually digitized. The Upper Mississippi River System includes the Mississippi River from Cairo, Illinois to Minneapolis, Minnesota and the Illinois River for a total of 1300 river miles. 1.2.2 Purpose: To produce a detailed map of terresterial and aquatic land cover and land use of the Upper Mississippi River floodplain for trend analysis. 1.2.3 Supplemental Information: Aerial photography was collected for the entire Upper Mississippi River in 1989 and several pools have been similarily mapped with a goal of creating a systemic database of land cover/use. 1.3 Time Period Information 9.1.1 Single Calendar Date: 19890915 1.3.1 Currentness Reference: Ground Condition 1.4.1 Progress: In Work 1.4.2 Maintenance and Update Frequency: As Needed 1.5.1.1 West Bounding Coordinate: -93.144 1.5.1.2 East Bounding Coordinate: -87.3112 1.5.1.3 North Bounding Coordinate: 45.061 1.5.1.4 South Bounding Coordinate: 36.858 1.6.1.1 Theme Keyword Thesaurus: None 1.6.1.2 Theme Keywords: Land cover 1.6.1.2 Theme Keywords: Land use 1.6.1.2 Theme Keywords: Vegetation 1.6.1.2 Theme Keywords: Wetlands 1.6.2.1 Place Keyword Thesaurus: None 1.6.2.2 Place Keywords: Minnesota 1.6.2.2 Place Keywords: Wisconsin 1.6.3.1 Stratum Keyword Thesaurus: None 1.6.4.1 Temporal Keyword Thesaurus: None 1.6.4.2 Temporal Keywords: late summer 1.7 Access Constraints: None 1.8 Use Constraints: None 1.9 Point of Contact Information: 10.1.1 Contact Person: Marc Thomas 10.1.2 Contact Organization: BLM, OR 10.1.2 Contact Organization Primary: BLM.

Some comparison may be done on-screen if areas on the test plot are unclear. The attributes are also checked against an all inclusive list of possible attributes for the data set. If needed the attributes are also verified to the photo interpretation for the data set. 2.2 Logical Consistency Report: All polygon features are checked for topology using the ARC/INFO software. Each polygon begins and ends at the same point with the node feature. All nodes are checked for error so that there are no dangling features. There are no duplicate lines or polygons. All nodes will snap together and close polygons based on a specified tolerance. If the node is not with the tolerance it is adjusted manually. The tests for logical consistency are performed in ARC/INFO using certain commands. 2.3 Completeness Report: All data that can be photo-interpreted is also digitized. This includes submergent classes, emergents, grasses, trees and also linear features such as streams and banks. 2.4.1.1 Horitzonal Positional Report: Horizontal positional accuracy is tested by visual comparison of the data with hard copy maps and on-screen with existing data sets that cover the same area. 2.5.1.1 Source Citation: 8.1 Orginator: Environmental Management Technical Center 8.2 Publication Date: 19950829 8.4 Title: 1989 Land Cover/Land Use on the Upper Mississippi River System 8.6 Geospatial Data Presentation Form: Map 8.8.1 Publication Place: Environmental Management Technical Center 8.8.2 Publisher: Environmental Management Technical Center (EMTC) 8.9 Other Citation Details: White, B.

Photo interpretation was performed with a Bausch and Lomb 240 zoom stereoscope at 6X magnification using 4x0 drafting pens on clear acetate overlays registered to photo transparencies. The minimum mapping unit was the smallest area that could be delineated (approximately 80 mē). Extensive ground truthing was performed along with the interpretation. Data were transferred from photo overlays to mylar overlays registered to USGS 7.5' quadrangle enlargements at a scale of 1:15,000, using a Bausch & Lomb zoom transfer scope. All data were transferred and were digitized into ARC/INFO on Altek digitizing tables (absolute accuracy 0.001 inch up to +/- 0.003 inch). No data reduction or generalization in transferring or digitizing took place. 2.5.2.6 Process Contact: 3 Spatial Data Organization Information 3.2 Direct Spatial Reference Method: Vector 3.3.1.1 SDTS Point & Vector Object Type: Label Point 4 Spatial Reference Information 4.1.2.2.1 Grid Coordinate System Name: Universal Transverse Mercator(UTM) 4.1.2.2.2.1 UTM Zone Number: 15 4.1.4.1 Horizontal Datum Name: North American Datum of 1927 4.1.4.2 Ellipsoid Name: Clarke 1866 5 Entity and Attribute Information 5.2.1 Entity/Attribute Overview: The database contains many different attributes. The different attributes represent the data in a generalized and specific manner. The most specific attributes describe the vegetation to the genus level of classification. The specific genus levels have also been categorized into 13 general vegetation classes. The attributes contain numerical codes and descriptors. Modifiers also exist representing percent of vegetation cover and tree height. The classification system used for attributing this data set is the LTRMP VEGETATION CLASSIFICATION. Contact Tom Owens at the Environmental Management Technical Center for more information on the classification system. 6 Distribution Information 6.1 Distributor: 10.1.1 Contact Person: Lisa Blackburn 10.1.2 Contact Organization: BLM OR/WA 10.3 Contact Position: Records Administrator 10.4.1 Address Type: Mailing Address 10.4.2 Address: P.O.
