This map presents land cover and detailed topographic maps for the United States. It uses the USA Topographic Map service. The map includes the National Park Service (NPS) Natural Earth physical map at 1.24km per pixel for the world at small scales, i-cubed eTOPO 1:250,000-scale maps for the contiguous United States at medium scales, and National Geographic TOPO! 1:100,000 and 1:24,000-scale maps (1:250,000 and 1:63,000 in Alaska) for the United States at large scales. The TOPO! maps are seamless, scanned images of United States Geological Survey (USGS) paper topographic maps.
The maps provide a very useful basemap for a variety of applications, particularly in rural areas where the topographic maps provide unique detail and features from other basemaps.

This digital terrain model represents historical elevations along the valley of the North Fork Toutle River upstream of its confluence with the Green River in Cowlitz and Skamania Counties, Washington. Most elevations were derived from U.S. Geological Survey 1:62,500 scale topographic quadrangle maps published from 1953 to 1958 that were derived from aerial photographs taken in 1951 and 1952. Elevations representing the bed of Spirit Lake, at the head of the valley, were derived from a bathymetric map based on survey data from 1974. Elevations are in units of meters and have been adjusted to the North American Vertical Datum of 1988.
Topographic map of Greenland, 1:250 000, 80 V.1 Washington Land. 400 dpi. Coloured maps at 1:250 000 with contour interval 100 m. A set of 53 digital maps covers North and North-East Greenland from lnglefield Land in the west to Scoresby Sund in the east. One additional sheet provides an index map and a legend. The maps show the usual range of physiographic features, viz. coasts, rivers, lakes and ice. They are coloured with a 100 m contour interval over both land and ice, and with selected spot heights in metres. They have been drawn at the Survey from air photographs using Kort & Matrikelstyrelsen (KMS) ground control points and aerotriangulation. Map projection is Universal Transverse Mercator, zone 24. The maps are a sequel to a set of geological sheets at the same scale but with four extra sheets covering lnglefield Land and Humboldt Gletscher.

Ecology created the GIS statewide river mile point layer in March 2007 by digitizing the river mile points depicted on the USGS 7½ minute (24k) topographic quadrangle maps. Some of the rivers have gaps in the river mile progression because several of the quadrangle maps do not have any river mile points, while a few were missing a point or two.In November 2014 Ecology added river mile points for the missing areas using Washington Department of Fish and Wildlife's (WDFW) 1975 Stream Catalog, which only covers WRIA's 1 through 24. The Stream Catalog shows river miles for nearly every stream; however, only those water courses that have river miles from the USGS quadrangle maps were added.The field SOURCE denotes the source of the data point, USGS or WDFW. Discrepancies between the USGS and WDFW are documented in the Supplemental Information section.

Digital elevation models (DEMs) of the lower Elwha River, Washington, were created by synthesizing lidar and PlaneCam Structure-from-Motion (SfM) data. Lidar and still digital photographs were collected by airplane during surveys from 2012 to 2016. The digital photographs were used to create a SfM digital surface model. Each DEM represents the ending conditions for that water year (for example, the 2013 DEM represents conditions at approximately September 30, 2013). The final DEMs, presented here, were created from the most recent lidar before September 30 of a given year, supplemented with an error-corrected SfM model from a low-flow summer Elwha PlaneCam flight as close to 30 September as possible. This synthetic data product was created because the aerial lidar data had gaps near the river, which the SfM data were able to close. The georeferenced DEMs were used to assess the river's responses to the removal of the Elwha and the Glines Canyon dams upstream from the study area.

These are military topographic maps (scale 1:25,000) from the years 1944, series GSGS 4427 and GSGS 4414 (GSGS = Geographical Section General Staff). During the Second World War, maps of strategically located areas in the occupied territories were produced on the initiative of the American Army Map Service (AMS) in Washington DC and the British War Office in London. The work of the military services includes maps of cities and map series of France, Belgium and the Netherlands, among others. This includes the map series "Holland, 1:25.000" which was known to the Americans under the code AMS M831 and to the British under the code GSGS 4427. The 215 sheets in series GSGS 4427 contain most of the Netherlands, and were published in 1943. , 1944 or 1945 printed. From series GSGS 4414 there are 263 maps of the eastern part of the Netherlands and a large part of Germany. Older sheets available in Washington DC and London were used to make the maps. Sometimes it was even necessary to refer to information printed by the Dutch Topographical Service from the end of the nineteenth century. If the Allies had more recent magazines, they were of course used. In most cases, information was taken from map sheets from the 1920s and 1930s. In addition, information was also taken from, for example, Michelin maps and map sheets of the Koninklijke Nederlandsche Automobiel Club (KNAC).
The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. Spatial data from observation points and quantitative plots were used to edit the formation-level maps of George Washington Birthplace National Monument to better reflect homogeneous vegetation classes. Using Arcview 3.3, polygon boundaries were revised onscreen over leaf-off photography. Units used to label polygons on the map (i.e. map classes) are equivalent to one or more vegetation classes from the regional vegetation classification, or to a land-use class from the Anderson Level II classification system. Each polygon on the George Washington Birthplace National Monument map was assigned to one of 19 map classes based on plot data, field observations, aerial photography signatures, and topographic maps.

This map features a detailed basemap for Washington, DC, including buildings and landmarks in the District. The basemap includes coverage down to about 1:1,000 for the full District of Columbia.The map is based on data from the DC Geographic Information Systems Program (DC GIS). The mission of the DC GIS is to improve the quality and lower the cost of services provided by the DC government, through the District's collective investment and effective application of geospatial data and systems.The map is authored using the World Topographic Map Template for Large Scales. Washington, DC is one of the featured areas of the World Topographic Map. The World Topographic Map includes detailed maps for several cities and areas around the United States.
