LiDAR data”if collected, analyzed and disseminated to local residents and policy makers”can be invaluable in mapping landslide hazards. In turn, such mapping can greatly help mitigate the consequences of landslides. After the Oso disaster, interest in landslide hazards grew significantly in Washington as well as Oregon, California and other mountainous states.

Drones and New Applications for Precision Agriculture

Drones and New Applications for Precision Agriculture

Basic crop scouting from drones provides a major improvement over how field surveys previously were done, and it's the primary driver for drone-technology adoption. Crop scouts traditionally were employed to walk farm fields to monitor crop condition. This is hot, time-consuming work, and crop scouts have difficulty visiting even a small percentage of a whole field, easily missing problem areas.
