Basic Forest Inventory with UAV Structure from Motion

In this post I show a simple way to use UAV-derived Structure from motion (SfM) point cloud data to segment and measure some trees.

UAV-derived estimates of forest structure to inform ponderosa pine forest restoration

Restoring forest ecosystems has become an increasingly high priority for land managers across the American West. Millions of hectares of forest are in need of drastic yet strategic reductions in density (e.g., basal area). Meeting the restoration and …

Estimating forest restoration treatment effects on forest structure: Multi-temporal UAV SfM model and multispectral image analysis

The ponderosa pine (Pinus ponderosa) forests across Arizona have undergone significant changes in their structure and composition since European-American settlement in the 1860's. At present, Southwestern ponderosa pine forests are dense with …
