Montana State Library 20020130 Helena, Montana Montana State Library https://ftpgeoinfo.msl.mt.gov/Data/Spatial/NonMSDI/Shapefiles/GreaterYellowstoneDLG_2002.zip These layers cover an area around Yellowstone and Grand Teton National Parks in Montana, Wyoming, and Idaho. Data for the national parks themselves are not included. The data were digitized by the US Geological Survey and provided to the public as Digital Line Graph files. The dates of the source maps ranged from 1948 through 1998. The data were provided as separate files for each 7.5-minute quadrangle by the USGS. The State Library joined the individual themes into two groups of layers - one for Montana and another for Wyoming and Idaho. The USGS major and minor attribute codes have been replaced with the codes shown in this metadata record. A few of the DLG files had coordinates in the NAD83 datum, while most were in NAD27. Because of the diffrence between the position of the quadrangle boundaries between NAD83 and NAD27, there are gaps in the data, generally about 200 meters wide, between adjacent quadrangles that have different datums. These data have been removed from the State Library web site because they are obsolete and better recent data may be available. These data are still available on request from the State Library data archive. The following feature classes are available in the archive: . quad_dates - Data index polygon features . dlghd1a - Hydrography line features, Montana . dlghd3a - Hydrography line features, Wyoming and Idaho . dlghd2 - Hydrography polygon features, Montana . dlghd4 - Hydrography polygon features, Wyoming and Idaho . dlghd1b - Hydrography node features, Montana . dlghd3b - Hydrography node features, Wyoming and Idaho . dlghd1c - Hydrography point features, Montana . dlghd3c - Hydrography point features, Wyoming and Idaho . dlgrd1 - Road line features, Montana . dlgrd2 - Road line features, Wyoming and Idaho . dlgrd1b - Road node features, Montana . dlgrd2b - Road node features, Wyoming and Idaho . dlgrr1b - Railroad node features, Montana . dlgrr2b - Railroad node features, Wyoming and Idaho . dlgrr1 - Railroad line features, Montana . dlgrr2 - Railroad line features, Wyoming and Idaho . dlgmt1a - Miscellaneous Transportation line features, Montana . dlgmt1b - Miscellaneous transportation node features, Wyoming and Idaho . dlgmt1c - Miscellaneous transportation point features, Montana . dlgmt2a - Miscellaneous Transportation line features, Montana . dlgmt2b - Miscellaneous transportation node features, Wyoming and Idaho 1948 1998 Publication Date -111.875 -109.375 46.375 44.125 ISO 19115 Topic Category inlandWaters transportation utilitiesCommunication Hydrography Streams Rivers Lakes Marshes Wetlands Swamps Canals Ditches Roads Highways Trails Streets Railroads Airports Pipelines Transmission lines Power lines Powerlines Ski lifts Montana None The Montana State Library provides this product/service for informational purposes only.

Helena MT 59620-1800 406-444-5354 Montana Relay 711 406-444-0266 geoinfo@mt.gov http://docs.msl.mt.gov/geoinfo/Images/Metadata/dlgcf1.gif Attributes were interpreted from the original DLG files by a computer program. The accuracy of this interpretation has not been extensively checked. Attribute accuracy of the original Digital Line Graph data is estimated by the USGS at 98.5 percent, and was tested by them as follows: - manual comparison of the source with hard copy plots. - symbolized display of the digital line graph on an interactive compter graphic system. - Selected attributes that could not be visually verified on plots or on screen, were interactively queried and verified on screen. In addition, U.S. Geological Survey (USGS) Production System (PROSYS) software tested the attributes against a master set of valid attributes for the category; it also checked for selected valid attribute combinations, and for valid attributes relative to topology and dimensionality. All attribute data conform to the attribute codes current as of the date of digitizing. The coverage only contains point and node attributes for the 13 quadrangles that were imported in 1997. For DLG data, Digital Revision Status = Not revised: Data completeness reflects the content of the source quadrangle. Features may have been eliminated or generalized on the source graphic, due to scale and legibility constraints. For DLG data, Digital Revision Status = Limited Update: This file has undergone limited update digital revision. The file contains only (1) those features that are photoidentifiable on monoscopic source, supplemented with limited ancillary source, and (2) those features, present on the original source quadrangle, that can not be reliably photoidentified but that are not considered particularly prone to change. For DLG data, Digital Revision Status = Standard Update: This file has undergone standard update digital revision. The data completeness of this file meets National Mapping Division standards for feature content. Approximate accuracy is 12 meters, assuming the source maps meet National Map Accuracy Standards (NMAS). NMAS horizontal accuracy requires that at least 90 percent of points tested are within 0.02 inches of the true position. The digital data are estimated to contain a horizontal positional error of less than or equal to 0.003 inches standard error in the two component directions relative to the source quadrangle. Comparison to the graphic source is used as control to assess digital positional accuracy. Cartographic offsets may be present on the graphic source, due to scale and legibility constraints. Digital map elements require edge alignment between data sets. Data along each quadrangle edge are tested against the data set for the adjacent quadrangle using PROSYS; tests check for positional accuracy between data sets within a 0.02 inches tolerance. Features with like dimensionality, and with or without like attribution, that are within the tolerance are adjusted by moving the feature equally in both data sets. Features outside the tolerance are not moved.
