This dataset shows all the USGS 7.5' quads for the United States. This dataset was obtained from GIS Data Depot.

Set of all the USGS 24k Quadrangle maps that intersect Eaton County, Michigan.The quadrangles included are Aurelius, Bellevue, Charlotte, Chester, Dimondale, Duck Lake, Eagle, Eaton Rapids, Hoytville, Lansing North, Lansing South, Nashville, Needmore, Olivet, Onondaga, Portland South, Saubee Lake, Springport, Wacousta, and Woodbury. They are all the 2019 versions of the maps except Needmore, which is 2017. These maps were acquired by download from the National Map Viewer.https://www.usgs.gov/core-science-systems/ngp/tnm-delivery/ on 1/9/2020.

QUADRANGLES_24K_USGS_IN is a polygon shapefile defining the boundaries of the USGS 7.5-minute (1:24,000-scale) quadrangles which cover the state of Indiana. Dates of publication and photorevision of paper quadrangle maps published by the U.S. Geological Survey are also provided.

The USGS 24k Quad Boundaries dataset is an index that shows where the USGS 1:24,000-scale quadrangle maps are located in Mono County.

USGS 24K quads in Kansas

Reference map for the 250K, 100K, and 24K USGS quad maps. Names and codes labelled.The full Kansas geospatial catalog is administered by the Kansas Data Access & Support Center (DASC) and can be found at the following URL: https://hub.kansasgis.org/

The 1:24,000-scale (24K) U.S. Geological Survey (USGS) quadrangle boundary data set contains the following information. (1) The approximate boundaries of the various 24K USGS quadrangles. (2) The names and indexing codes associated with each 24K quadrangle. And (3) information on which 1:100,000- (100K) and 1:250,000-scale (250K) quadrangle each 24K is associated with.

USGS quadrangle basemaps to be displayed with the Surficial Geology (24k) data, published as a hosted cached tile service by MassGIS. The imagery displays at three zoom scales: 1:18,056, 1:9,028, and 1:4,514.MassGIS downloaded a set of georeferenced tiff images for each quadrangle from https://pubs.er.usgs.gov/publication/sim3402. These are the old-series (1944-1977 editions) topographic quadrangles (1:24,000 scale), most of which have the same contour base (10-ft contour interval) as the original geologic mapping. Paper quadrangle maps were scanned and georeferenced by the Office of the Massachusetts State Geologist for this project. Each of these images has an associated layer file which colormaps the image so that the white background becomes transparent; they should be used on top of the geologic data layers.

This index provides information and download links for the 968 digital raster quadrangle maps produced by NYS Department of Transportation. An outline for each 7.5-minute quadrangles is provided. The referenced digital maps were produced for use at 1:24,000 scale. Attributes are: REFCODE - NYS reference code associated with 7.5 minute quad; QUADNAME - Quad Name; DOTDATE - Date of NYS/DOT raster quad; CONDATE - Date of contours on NYS raster quad; CON_INTER - NYS raster quad contour interval; CON_UNITS - NYS raster quad contour units; SCANTYPE - Type of NYS raster quad product; ADDLAYERS - Additional NYS raster layers available; USGSCODE - USGS 7.5x7.5 minute quad code; ZONES - List of State Plane zones in quad; COUNTIES - Counties covered in part by quad The maps are in Zone 18 of the UTM grid/projection system. The information in the index represents the status as of 2004 when updates to the maps ended.Please contact NYS ITS Geospatial Services at nysgis@its.ny.gov if you have any questions.

This polygon layer provides an index grid based on latitude and longitude intervals corresponding to the USGS topographic quadrangle series at 1:24,000 scale. The latitude/longitude interval corresponding to this quadrangle index is 7.5 minutes latitude by 7.5 minutes longitude.

This data set uses a shapefile from the California Department of Water Resources which was digitized from the "Sacramento River, Sloughs, and Tributaries, California, 1991 Aerial Atlas, Collinsville to Shasta Dam" published by the US Army Corps of Engineers, Sacramento District. This atlas was used by biologists while they were surveying for bank swallows from 1992 to 2000. The May 1984 edition of this atlas was used for locating river mile points during surveys from 1986 to 1991. River mile points in both atlases vary from those shown on USGS 24k quad maps and are provided here to facilitate the locating of the bank swallow nesting colonies which are described by river mile.

The elevation points found in this layer were derived for the 1:24,000 scale United States Geologic Survey (USGS) map series for the region. The majority of the points came from the digital United States Forest Service (USFS) Cartographic Feature Files (CFFs). Areas in which digital source could not be found where derived by digitizing the features off the USGS 1,24,000 scale quads. This was done by digitizing the points off the USGS maps.
