    Description

    This dataset was created to support the Washington D.C. StreamStats project funded by the Washington D.C. Department of Energy and Environment (DOEE). The dataset contains digital elevation model (DEM), flow direction and catchment layers that were conditioned using Washingtons D.C.’s stormwater network layer. The data are hosted online as a component of the USGS StreamStats web application (https://streamstats.usgs.gov), where users can interact with a map of Washington D.C.’s stormwater pipe system and National Hydrography Dataset (NHD) “best resolution” blue lines to delineate drainage basins that account for pipe flow. This project utilized 1-meter (high resolution) terrain products, which improves upon existing 10 meter resolution data products traditionally used in StreamStats. Following work completed for Boston’s Mystic River Basin, Washington, D.C. is the second jurisdiction to incorporate storm-drain-network data into StreamStats. The pipe-network-informed hydro-geomorp ...

    Description

    Important Note: This item is in mature support as of June 2021 and is no longer updated.

    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.

    To add this map service into a desktop application directly, go to the entry for the USA Topo Maps map service.

    Tip: Here are some famous locations as they appear in this web map, accessed by including their location in the URL that launches the map:

    Grand Canyon, Arizona

    Golden Gate, California

    Mass Points (2008). The dataset contains DTM masspoints derived photogrammetrically to support 2’ contours. Masspoints and breaklines were compiled from Spring 2008 aerial photography using softcopy photogrammetric techniques. Masspoint elevations are in based on NAVD US feet. Masspoints and breaklines were compiled to support generation of a TIN and the subsequent processing of 2’ contours.

    Description

    A 1/3 arc-second Mean Lower Low Water bathymetric DEM of NOS hydrographic survey data in Chesapeake Bay.A map service showing the location and coverage of land and seafloor digital elevation models (DEMs) available from NOAA's National Centers for Environmental Information (NCEI). NCEI builds and distributes high-resolution, coastal digital elevation models (DEMs) that integrate ocean bathymetry and land topography to support NOAA's mission to understand and predict changes in Earth's environment, and conserve and manage coastal and marine resources to meet our Nation's economic, social, and environmental needs. They can be used for modeling of coastal processes (tsunami inundation, storm surge, sea-level rise, contaminant dispersal, etc.), ecosystems management and habitat research, coastal and marine spatial planning, and hazard mitigation and community preparedness. Layers available in the map service: Layers 1-4: DEMs by Category (includes various DEMs, both hosted at NCEI, and elsewhere on the web); Layers 6-11: NCEI DEM Projects (DEMs hosted at NCEI, color-coded by project); Layer 12: All NCEI Bathymetry DEMs (All bathymetry or bathy-topo DEMs hosted at NCEI).This is an ArcGIS image service showing color shaded relief visualizations of high-resolution digital elevation models (DEMs) of U.S. coastal regions. NOAA's National Geophysical Data Center (NGDC) builds and distributes high-resolution coastal digital elevation models (DEMs) that integrate ocean bathymetry and land topography to support NOAA's mission to understand and predict changes in Earth's environment, and conserve and manage coastal and marine resources to meet our Nation's economic, social, and environmental needs. They can be used for modeling of coastal processes (tsunami inundation, storm surge, sea-level rise, contaminant dispersal, etc.), ecosystems management and habitat research, coastal and marine spatial planning, and hazard mitigation and community preparedness. DEMs included in this visualization: High-resolution DEMs of select U.S. coastal communities and surrounding areas. Most are at a resolution of 1/3 to 1 arc-second (approx 10-30 m); U.S. Coastal Relief Model: A 3 arc-second (approx 90 m) comprehensive view of the conterminous U.S. coastal zone, Puerto Rico, and Hawaii; Southern Alaska Coastal Relief Model: A 24 arc-second (approx. 500 m) model of Southern Alaska, spanning the Bering Sea, Aleutian Islands, and Gulf of Alaska. This map service can be used as a basemap. It has a transparent background, so it can also be shown as a layer on top of a different basemap. Please see NGDC's corresponding DEM Footprints map service for polygon footprints and more information about the individual DEMs used to create this composite view.

    Description

    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).
