Data Acquisition and Processing

Data Acquisition Methods

DMS is a visible imaging system, capturing data throughout flight. Level-0 products for raw DMS include raw JPEG files. Most imagery was acquired in panchromatic mode, but all provided output is 3-banded imagery.

Sensor or Instrument Description

The DMS airborne digital camera acquires high-resolution natural color and panchromatic imagery from low and medium altitude research aircraft. The system configuration includes a 21 megapixel Canon EOS 5D Mark II digital camera, a computer-controlled intervalometer, and an Applanix POS/AV precision orientation system. In-flight operators maximize image quality with adjustments to exposure and intervalometer settings.
