Aerial Photography (Orthophoto) - 2015

2015 Orthophoto - 3 inch resolution imagery service. Data produced for the District of Columbia from 2015 digital aerial photography. It was flown in mid-April and, completed on April 24th, 2015.

Further details included in download XML file.

DUE TO THE LOW ALTITUDE FLOWN TO CAPTURE THE COMPLETE IMAGERY FOR THE 2015 SENSOR FLIGHT, THERE IS INCOMPLETE AERIAL PHOTOGRAPHY COVERAGE AROUND THE WHITE HOUSE AND CAPITOL.  FOR THESE AREAS, 2013 IMAGERY WAS MERGED IN USING STREET CENTERLINES TO DEFINE THE 2013 MERGE AREAS TO MINIMIZE DISTORTION OF FEATURES.  The project area covers the entire District of Columbia which is approximately 69 square miles. The digital imagery was used to create natural color digital orthophotography with 8cm pixel resolution. The final orthophotography deliverable products for this project consist of 328 ortho tiles at a scale of 1 to 2400. The tile dimensions are 800 meters by 800 meters. A corresponding MrSid image was created by mosaicking the 328 ortho tiles together and compressing the image using an 80 to 1 compression ration.

(LIDAR) Data - 1m resolution. The dataset contains locations and attributes of
bare earth elevations in meters.  Bare earth model is created by
identifying those returns that fall on the ground surface and interpolating a
surface between these points.  In this manner buildings and vegetation are
removed from Bare Earth Model.   This data set does not include bridges
and overpasses in the Bare Earth model as the delineation point for these
structures is not reliably discernable in the LiDAR data.</span></p>

DC Forest Action Plan

The 2008 Farm Bill amended the Cooperative Forestry Assistance Act (CFAA) to require states to complete a statewide assessment of forest resource conditions and a long-term statewide forest resource strategy. The DC State Forest Action Plan (SFAP) is a comprehensive roadmap for investing federal, District, and private resources into managing and maintaining the urban forest.

Common DC wildlife includes bald eagles, bats, coyotes, deer, ducks, eastern box turtles, eastern cottontails, foxes, owls, woodchucks and more. </div><div><br /></div><div>Washington DC straddles two ecoregions, the Piedmont and the Southeast Plains ecoregion. The dominant native vegetation on most of the well-drained loamy soil of the Piedmont is deciduous forest, and the native vegetation for the Southeast Plains in the District is mostly hardwoods with some softwoods.</div>

The degree of uncertainty for an estimate arising from sampling variability is represented through the use of a margin of error. The value shown here is the 90 percent margin of error. The margin of error can be interpreted as providing a 90 percent probability that the interval defined by the estimate minus the margin of error and the estimate plus the margin of error (the lower and upper confidence bounds) contains the true value.

The layer always contains the latest available ACS 5-year estimates. It is updated annually within days of the Census Bureau's release schedule. Boundaries come from the US Census TIGER geodatabases.
