Geological Survey Online_Linkage: http://geopubs.wr.usgs.gov/i-map/i797/ Description: Abstract: Four film positives of topography [which was prepared in 1943 and subsequently used by Page and Nokleberg (1974) for a base map for the geology of the Stillwater Complex, Montana] were scanned, and the resulting TIFF images were then geoferenced, rectified, and spliced together to create i797base.tif. Purpose: This image was prepared for archival purposes and is not meant to be used or displayed at any scale larger than 1:12000 (for example. 1:2000). Time_Period_of_Content: Time_Period_Information: Single_Date/Time: Calendar_Date: 1943 Currentness_Reference: Date that topographic map was created.

Jeremy Larsen (Eastern Washington University) georeferenced and rectified the resulting TIFF images. Robert J. Miller then merged the four TIFF images into a single image, i797base.tif. Native_Data_Set_Environment: Microsoft Windows 2000 Version 5.0 (Build 2195) Service Pack 2; ESRI ArcCatalog 8.1.1.649 Data_Quality_Information: Logical_Consistency_Report: The topography in the scanned image matches fairly well with the topography in the scanned images of the Page and Nokleberg map (1974) and with the geology portrayed in i797.e00 (Page and others, 2002). Completeness_Report: The scanned image is an accurate representation of the original (1943) film positives. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The individual scanned images of parts of the basemap typically had an RMS error of approximately 3 meters. However, where parts of the georeferenced scans overlap, local shifts of up 15 meters were noted.

Process_Step: Process_Description: Low resolution scans (100 dpi) of portions of the basemap were georeferenced and converted to ArcInfo grids. The grids were clipped and merged into a single file then saved in a TIFF format. Process_Contact: Contact_Information: Contact_Person_Primary: Contact_Person: Robert J.
