  Unmanned Aerial Vehicles (UAVs) equipped with LiDAR, electro-optical and
infrared cameras, SAR and atmospheric sensors have transformed the way we
acquire high spatio-temporal resolution data. For example, UAVs equipped with
these sensors have been able to obtain topography at resolutions of less than
one meter, revolutionizing earth sciences. Surface processes act at spatial
scales on the order of a meter to produce intricate landforms and UAVs equipped
with these sensors are able to measure the three dimensional spatio-temporal
geometry of the earths surface and overlying anthropogenic features and
vegetation at resolutions appropriate to document these processes. In addition,
surface changes due to erosion, transport and sedimentation, as well as
earthquakes, landslides, volcanoes can be quantified with this data.
