UAV-based Mobile Mapping: Potential, Challenges and Outlook 


Accurate representation and 3D reconstruction of the environment using both active and passive remote sensing systems has become essential for non-traditional mapping applications. Due to the excessive cost as well as the required level of technical expertise, the needs of these applications cannot be satisfied by traditional mapping, which is based on dedicated data acquisition systems designed for mapping purposes (e.g. manned airborne and terrestrial mobile mapping systems). Recent advances in hardware and software development have made it possible to conduct accurate 3D mapping without using costly and high-end data acquisition systems. Low-cost digital cameras, laser scanners and navigation systems can provide accurate mapping if they are properly integrated at the hardware and software levels.

In conjunction with recent developments in sensor technology, unmanned aerial vehicles (UAVs) are emerging as a mobile mapping platform that can provide additional economical and practical advantages.
