Airborne and spaceborne imagery for mapping

Airborne and spaceborne imagery is becoming widely used for manymapping purposes. The diverse information that can be acquired from airborneand spaceborne sensors solve many of the demands for the global study of theEarth. The paper concentrates on mapping from non-classical photogrammetriccameras. A survey of a few sensors and existing imagery considered by theauthor the most relevant is also presented. The characteristics of these sensorsand the resulting imagery and resolution are also summarized. Its suitability formapping at local, regional and global scales is examined.
