Service Description:

Resolution: 0.25 Meter

Band: 3-band: G, R, NIR

EarthDataDelivered as 2010 tiles.Each tile is 1.7km x 1.7km, 6800x6800 pixels, and 135MB (TIF). SRS: NAD83 HARN Delaware State Plane metersScale: 1:2,400

This false color IR digital orthophotography, at a scale of 2,400, was produced for the State of Delaware for the purpose of statewide base mapping by EarthData International of Maryland, LLC.

Compliance with the accuracy standard was ensured by the placement of GPS ground control prior to the acquisition of aerial photography. The following checks were performed. 1. The ground control and airborne GPS data stream were validated through a fully analytical bundle aerotriangulation adjustment. The residuals of the adjustment met the required standards for accuracy which are 1 part in 10,000 of the flying height for the horizontal position (X and Y) and 1 part in 9,000 or better of the flying height in elevation (Z). 2. The DTM data was checked against the project control. The technician visited and confirmed the accuracy of the project mass points during initial compilation. 3. Digital orthophotography was validated through an inspection of edge matching and visual inspection for image quality

Aerial photography was acquired using a flight design that included a total of 1196 exposures in 20 North-South oriented flight line. Aerial photography was exposed on Kodak CIR film 1443, emulsion number 1133012. Aerial photography was supplemented with the simultaneous acquisition of airborne GPS data, which captured the ground coordinate for the nadir point of each photograph. Aerial photography was exposed at an altitude of 11,000' above mean terrain yielding an approximate scale of 1 / 21,600.
