This dataset contains locations and attributes of 2-ft interval topography data in 2008. Created as part of the DC Geographic Information System (DC GIS) for the D.C. Office of the Chief Technology Officer (OCTO) and participating D.C. government agencies. In addition to the 2-ft contour data ancillary datasets containing an ESRI geodatabase of masspoints and breaklines.

0.6 meter contours. This dataset contains locations and attributes of 0.6 meter interval topography data, created using bare earth points from the lidar point cloud data. Some areas have limited data. The lidar dataset redaction was conducted under the guidance of the United States Secret Service. All data returns were removed from the dataset within the United States Secret Service redaction boundary except for classified ground points and classified water points.

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.

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 ...

Topographic map on a scale of 1: 10,000 in the 1992 layout is a graphical map (in colour). It shows the shape and cover of the land (including water, vegetation, settlements, roads and a number of other objects). Topographical maps are the primary source of information about the geographical environment. Topographic map on a scale of 1: 10,000 in the 1992 layout is a graphical map (in colour).

The topographic maps referred to as the Issue State (AS) were primarily intended for military use and were classified as Confidential Classified. On a scale of 1: 25,000 there were 2 output variants: TK=topographic maps and TSP=topographic city maps.

This dataset contains locations and attributes of 0.6 meter interval topography data, created using bare earth points from the lidar point cloud data.Voids exist in the data due to data redaction conducted under the guidance of the United States Secret Service. All lidar data returns and collected data were removed from the dataset based on the redaction footprint shapefile generated in 2017.

The topographical maps, referred to as the issuing State (AS), were primarily for military purposes and carried the classification level of Confidential classified information. In scale 1: There were 25,000 output variants: TK=topographic maps and TSP=topographic city maps.

The District of Columbia jurisdiction and administrative boundary. The boundary was identified from public land records and digitized using a combination of sources including the 1995 orthophotographs, planimetric data for roads features, U.S. Geological Survey Digital Raster Graphic quad sheets, and the 1999 planimetrics boundary for the Potomac River.This DC boundary is used for the administration, planning, and management of Washington, D.C. by local DC government agencies, commissions and boards. Other administrative legal boundaries such as DC Wards, Advisory Neighborhood Commissions, and Single Member Districts are nested within the DC Administrative boundary.Orthophotography - a computer-generated image of an aerial photograph in which displacements (distortions) caused by terrain relief and camera tilts have been removed. It combines the image characteristics of a photograph with the geometric qualities of a map. Unlike an aerial photograph, an orthoimage has a uniform scale, so it can be used as a base map onto which other map information is overlaid and created. These images, known as orthophotos or orthoimages, provide a consistent scale that enables accurate representation of the District of Columbia's surface. Source: USGS.govPlanimetrics Data - information that represents the horizontal position of features on the Earth's surface, such as roads, buildings, and bodies of water, without including elevation or relief information. This data is often used in mapping and geographic analysis. Source: wikipedia.orgDigital Raster Graphic (DRG) - a scanned image of a U.S. Geological Survey (USGS) topographic map. The scanned image includes all map collar information. The image inside the map neatline is georeferenced to the surface of the Earth. The DRG can be used to collect, review, and revise other digital data. Source: USGS.gov
