<br/><br/> Extensive research has been conducted using satellite and aerial imagery to observe vegetation status. Nonetheless. these platforms have limitations, particularly with regard to cost, limited spatial and temporal resolution. Remotely piloted vehicles (RPV) are effective, low cost alternatives to satellites and manned aircraft for acquiring high-resolution images.
