Image data collection activities are typically limited to the use of normal aerial photography techniques. This approach is often expensive and requires extensive ground control. The imagery is limited in the ability to see the sides of features or underneath the tree canopy. The Image Data Acquisition System IDAS provides a low-cost alterative to traditional aerial photography. IDAS couples inexpensive video technology with Global Positioning Satellite GPS technology to provide referenced video imagery in real time with minimal requirements for ground control and rigid flight plans. Additional sensors digital compass, gyroscope, and altimeter provide camera geometry regardless of the platform path. IDAS is a portable system that can be easily deployed on multiple platforms aircraft, boats, or ground vehicles. The data processing system couples the imagery, position, and camera geometry data with a terrain database to provide approximate ground locations for features imaged.
