Our experiences with acquiring and processing sub-decimeter resolution imagery from UAVs demonstrate that this approach is feasible and effective for rangeland mapping and monitoring. The UAV imagery offers opportunities to map vegetation species and quantify soil and vegetation patterns in ways not possible with aerial or satellite platforms. Very high resolution DEMs can also be derived. The small size, relative ease of use and quick deployment of UAVs has advantages over manned aircraft. Perhaps most importantly from a land manager’s perspective, UAVs can be deployed rapidly for near-instantaneous assessments of remote areas that are difficult or expensive to access on the ground. Such cost-effective image acquisition is required to plan and monitor restoration projects following fire and other events in a realistic timeframe (Herrick et al., 2006b)
