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).

These data were created as part of the National Oceanic and Atmospheric Administration Office for Coastal Management's efforts to create an online mapping viewer called the Sea Level Rise and Coastal Flooding Impacts Viewer. It depicts potential sea level rise and its associated impacts on the nation's coastal areas. The purpose of the mapping viewer is to provide coastal managers and scientists with a preliminary look at sea level rise (slr) and coastal flooding impacts. The viewer is a screening-level tool that uses nationally consistent data sets and analyses. Data and maps provided can be used at several scales to help gauge trends and prioritize actions for different scenarios. The Sea Level Rise and Coastal Flooding Impacts Viewer may be accessed at: http://www.coast.noaa.gov/slr This metadata record describes the digital elevation model (DEM), which is a part of a series of DEMs produced for the National Oceanic and Atmospheric Administration Office for Coastal Management's Sea Level Rise and Coastal Flooding Impacts Viewer described above.

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-geomorphologically correct urban hydrography layers were developed by incorporating 1-meter resolution lidar-derived elevation data and D.C.’s stormwater pipe data to approximate topography and stormwater flow. Users may access the “Washington, D.C. Stormwater” fixture on the StreamStats application to delineate drainage basins that approximate effective basin area in storm drain serviced areas. The contents of this data release include the following GeoTiffs: •demaoi.tif: 1-meter LiDAR derived digital elevation model for Washington D.C. and its tributaries (6 HUC-12 watersheds: NW Branch Anacostia, Lower Rock Creek, Nichols Run Potomac River, Lower Anacostia River, Pimmit Run- Potomac River, and Fourmile Run- Potomac River.) •Fdr.tif: 1-meter pipe-network-informed flow direction raster for Washington D.C. and its tributaries (excluding the Potomac River mainstem). Flow direction was informed by D.C.’s stormwater pipe network, and stormwater inlets are represented as sinks. •Cat.tif: 1-meter flow accumulation layer for Washington D.C. and its tributaries (excluding the Potomac river mainstem). This layer was created using pipe-network-informed flow direction layer. The catchment raster represents subcatchments within the study area draining to either sinks (stormwater inlets) or surface drainage lines (overland connectors or streams). The processing steps implemented to produce the raster layers contained in this dataset follow methods previously described by Spaetzel and others, 2022, are described in the associated metadata. Please note that the stormwater network coverage used to produce this data is protected and will not be made publicly available.

This data set includes ice motion and topography measurements that were taken by measuring movement and altitude of poles set in the West Antarctic Ice Shelf. The data was acquired by Global Positioning System (GPS) measurements of poles. The position of the poles was measured twice; once in 2000, and again in 2002. Movement of the poles in that time show the ice motion velocity and direction. GPS pole positions are given in latitude and longitude, and elevations are given in meters above the WGS1984 ellipsoid. The data are presented as tables in ASCII text files. Three maps of the area are included with the data tables.
