The Evolution of Imagery and Enabling Technologies
Imagery has come a long way from early efforts with primitive cameras in primitive aeroplanes. Large format cameras, stabilization and forward motion compensation made for imagery that could be used in a wide variety of mapping applications. GPS was a huge enabler in advancing the quality and efficiency of aerial photo acquisition. Satellite imagery and its evolution provided more choice and economy of scale enabled applications previously thought too expensive. Affordable high resolution digital imagery coupled with modern affordable sensors such as GPS and Inertial has enabled new terrestrial, airborne and satellite sourced applications using multiple image sensors. This presentation will explore the evolution of imagery from the early days to present and what we have to look forward to in the future.
