Item Identification

Title: 2014 Ketchikan, AK DMC 4-Band 8 Bit Imagery
Status: Completed
Publication Date: 2014-11-30
Abstract:

Digital orthographic imagery datasets contain georeferenced images of the Earth's surface, collected by a sensor in which object displacement has been removed for sensor distortions and orientation, and terrain relief. Digital orthoimages have the geometric characteristics of a map, and image qualities of a photograph. (Source: Circular A-16, p. 16)

Purpose:

Orthoimagery data are used during FIRM production, and have been kept separate from the other framework themes for future consistency with the NDOP registry.

ArcGIS 10.1; Microsoft Windows 7; Microsoft Office; Intergraph's suite of photogrammetric products including Z/I Inflight and GeoMedia OrthoPro

Data Quality

Horizontal Positional Accuracy:

Not tested

Completeness Report:

Orthoimagery has been collected and processed for all areas within the project study area

Quality Control Procedures Employed:

Orthoimagery flight lines have been examined to ensure that there was at least 60% along track overlap and 40% sidelap between frames. TIFFs were blended together to remove seams and corrected for any remaining radiometric differences between images.

Process Steps

Process Step 1

CC ID: 1312879
Description:

A flight crew acquired multispectral aerial photography with an Intergraph Z/I Imaging DMC (Digital Mapping Camera) from an Quantum Spatial, Inc twin engine, fixed-wing aircraft.

Airborne control and Inertial Measurement Unit (IMU) data was collected simultaneously with the photos. The DMC produces 4 band imagery with a radiometric resolution of 12 bit (4096 discrete possible values).

Image size is 7,680 x 13,824 pixels Spectral sensitivity is as follows: blue: 400-580 nm green: 500-650 nm red: 590-675 nm near infrared: 675-850 nm pan: approximately 360-1040 nm The forward motion compensator eliminates image blur.
