Publication_Date: 20000210 Title: Aztec (c36106a1) Enhanced Digital Raster Graphic Geospatial_Data_Presentation_Form: Map Publication_Information: Publication_Place: Red Lodge, MT Publisher: Beartooth Mapping, Inc. Description: Abstract: The Digital Raster Graphic (DRG) is a scanned image of a US Geological Survey (USGS) standard series topographic map that includes all collar information (e.g., legend, scale bar, index map, etc.) The DRGE is a non-proprietary product of a USGS DRG in which the map collar information has been removed. Purpose: The DRGE is useful as a source or background layer in a GIS, as a means to perform quality assurance on other digital products, and as a source for the collection and revision of DLG data. The DRGE can also be merged with other digital data, e.g. DEM's or DOQ's, to produce a hybrid digital file. The removal of the collar information allows the DRGE to be edge-matched and displayed simultaneously in a Geographic Information System.

Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: The DRGE is an 8-bit color image that employs a color palette to ensure uniform colors throughout a particular DRG series. All DRG's within a series must have the same RGB value. Logical_Consistency_Report: N/A Completeness_Report: According to the USGS, the DRG is a faithfully reproduced digital image of the original source map. Some differences may be detected between the source graphic used and the DRG due to the RGB values assigned that particular color. The intent is to recreate those colors as near as possible. Data completeness for DRG files reflect content of the source graphic. Features may have been eliminated or generalized on the source graphic due to scale and legibility constraints. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The datum of the published map is retained to be consistent with other USGS digital data.

USGS DRG production specifications are available on request from the National Mapping Division and Mid-Continent Mapping Center by contacting: Rolla-ESIC U.S.Geological Survey 1400 Independence Rd., MS231 Rolla, MO 65401-2602 Phone (573)308-3500 Facsimile (573)308-3615 E-mail to mcmcesic@usgs.gov World Wide Web: http://mcmcweb.er.usgs.gov/drg/ Process_Step: Process_Description: The DRG imagery was processed using the Spatial Analyst Extension to ArcView 3.1 (ESRI, Inc). The map collar was removed and portions of adjacent quadrangles were appended to the input image to produce a UTM rectangle output. DRGE images from the same map series (large, intermediate, and small scale) were processed by UTM zone to produce seamless output imagery within each Zone. Process_Date: 20000210 Process_Step: Process_Description: The output ArcView Grid was converted to a TIFF 6.0 / GeoTIFF 1.0 image using the GridIO API (ESRI, Inc.), LibTiff Library (Copyright 1988-1998 Sam Leffler, 1991-1998 Silicon Graphics, Inc) and LibGeoTiff Library.
