Unmanned aircraft typically have complementary sensors that can provide aircraft location along with imagery information and that support mission planning and route following [8, 15, 17]. Both multi-spectral and hyperspectral cameras are now available for small UAV. The aircraft are used to collect relevant sensor information and transmit the information to the ground control station for further processing. For example, advanced sensors are contributing to precision agriculture which uses the technology to determine crop nutrient levels, water stress, impacts from pests and other factors that affect yield. Advances in platform design, production, standardization of image georeferencing and mosaiking and information extraction work flow are required to provide reliable end products [64].
