Use the complete EM

spectrum

Objectives: ● Platform for dedicated and high-

quality experiments ● Calibration facilities and disseminating

processing procedures to the UAS user community

● Test use in a broad range of applications like habitat monitoring, precision agriculture and land degradation assessment

Outlook UARSF @ WUR

From mapping to monitoring ● Consistent signal in time (spatially and spectrally) ● Efficient processing chains -> real-time products ● Link UAS products with science fields and applications ● Integration with satellite and ground based sensors

● New UAS domains: forestry and thermal

● NL Regulations and towards Certification

● BNUC-S: Basic National UAS Certificate – Small Aircraft ● Operations Manual ● Theory Ground Course and Flight Examination ● ILT project exemption + TUG

Research <-> Commercial <-> End-users

● Exchange/flow of knowledge

● Sharing of protocols/best practices required

● Sharing and exchange of facilities

● regulatory frameworks
