Citation_Information Originator: Institute for a Sustainable Environment - University of Oregon (ISE) Publication_Date: March 1999 Title: 1850 dwelling unit population Edition: 1 Geospatial_Data_Presentation_Format: Spatial dataset Publication_Information Publication_Place: Eugene Publisher: ISE Online_Linkage: PNWERCDescription Abstract This is a point coverage of 1850 dwelling unit locations for the Willamette Valley. It was digitized and attributed using Dr. William Bowen's 1978 publication: The Willamette Valley--Migration and Settlement on the Oregon Frontier. Dr. Bowen combined Donation Land Claim certificates, township plats, and the cadastral surveys fo the U.S. General Land Office (GLO) with data from the 1850 federal census to complete his research. Purpose This coverage is intended as a thematic data layer showing the dwelling unit locations for 1850. This map is displayed in the Willamette River Basin Planning Atlas (PNW-ERC, 1998). Supplemental_Information Procedures_Used 1850 Census tabular data were entered into a spreadsheet to create the database file census1850.dbf. The 1850 dwelling unit analog map was scanned then geo-referenced with the Arc REGISTER command. An additional coverage showing the 1850 county boundaries was created using images from Dr. Bowens publication and a present county boundary coverage. The new 1850 county coverage was used to help register the scanned image. Each point on the image was screen digitized and identified uniquely by county and house number. The NCNTY_HSE field was added to the census1850.dbf database file and the DU1850 attribute table allowing for link opportunities in ArcView. Revisions Reviews_Applied_to_Data Reviews by in-house staff, two map product reviews by outside experts, and EPA peer review of the Willamette River Basin Planning Atlas. Related_Spatial_and_Tabular_Data_Sets census1850.dbf is the tabular dataset of the 1850 Population census schedule.

Completeness_Report See Procedures Used Positional_Accuracy Horizontal_Positional_Accuracy Horizontal_Positional_Accuracy_Report: Bowen reports that 78% of 1850 dwellings were located to within USGS map accuracy standards for 1:62,500 scale, and 15% were located to within 1.5 miles. Locational accuracy information for the remaining 7% is not reported. Digitization from a 6ft. milar scan of a paper manuscript compiled by Dr. Bowen altered the accuracy of point locations to an unknown degree.
