Ever wondered what
#lidar
point clouds reveal about forests? OpenForest4D’s new guide breaks down how elevation, return number, intensity, and classification describe forest structure.

Discover how
#lidar
reveals the size & location of individual Ponderosa Pines at Sunset Crater, AZ! Using advanced algorithms in lidR, we map tree height and crowns in stunning detail, informing forest ecology and management.

processing to map forest change at scale. Generate canopy height, cover & change products critical for monitoring
#wildfire
impacts and ecosystem dynamics. Code and example from

How many batteries does it take to do field work in the Jemez and the Hopi Buttes? 11+4+8+3+1. Funner than the rest of the doom and gloom

New paper! Rachel Adam did a great job leading this work. Thanks to PGE and ASU for support. Think about how we map potentially active faults.
