Using the scientific method, this project proposes bringing geospatial assessment tools to the agricultural field that serve to independently verify the flight path accuracy and stability aspects of any UAS sensor platform apart from sole reliance on ortho-stitching processing or sole reliance on on-board platform systems. In a field, a set pattern of elevation posts with global navigational satellite system (GNSS) obtained coordinates will be erected to be viewed from the Nadir orientation of any UAS. With any UAS autonomous platform equipped for optically tracking geospatial flight path metrics, the UAS flight path will follow the posted field pattern at various altitudes. The expected result will be a repeatable testing regimen that will be suitable in standardizing the assessment of any UAS sensor platform for flight path stability and accuracy where precision mapping and true global accuracy are needed such as in the management decisions for the geospatial input of treatments.(Download PDF) (Export to EndNotes)
