Abstract

The Canada Centre for Remote Sensing (CCRS) is developing a processing system for airborne electrooptical line imager data. The demand for airborne line imager data for precision work such as mapping has been limited in the past. There have been two fundamental reasons for this; the pixel resolution has typically been very coarse, and the spatial distortions due to uncompensated aircraft motion and attitude have degraded the imagery. Improvements in technology have made it possible to think in terms of overcoming these drawbacks to line imager data. At the same time, changes in the approach to mapping are occurring, which makes a direct digital input of data more attractive than has been the case in the past. Also, the need to register remote sensing data for multitemporal studies or for data base merging requires accurate pixel positioning.
