| 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. |

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
| 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. |
