Abstract
Small farms and community gardens play a unique and important cultural, economic and local food supply role. This study brings precision agriculture practices to fine scale farms and community gardens, by exploring integrated geospatial techniques, including sUAS imagery acquisition and Structure from Motion (SfM) 3D modeling. From the created 3D models, plant heights are measured and compared to field measurements for validation of accuracy. Multiple crop growth forms and maturation stages are observed in order to understand how different factors, such as height, canopy, density and growth form, influence accuracy.
