Summary

Unmanned aerial systems (UAS) were used to acquire high-resolution imagery of the Liberty Island Conservation Bank Wildlands restoration site in the Sacramento–San Joaquin Delta in California, with the goal of using structure-from-motion (SfM) photogrammetric techniques to derive a digital surface model, orthomosaic imagery, and a topographic point cloud. The survey was conducted using two Department of Interior-owned 3DR Solo quadcopters fitted with Ricoh GR II digital cameras featuring global shutters. The UAS were flown on pre-programmed autonomous flight lines at an approximate altitude of 120 meters above ground level. The flight lines were oriented roughly east-west and were spaced to provide approximately 66 percent overlap [...]

Purpose

These data were collected in support of ongoing field experiments and numerical modeling by the USGS and others, with funding from the U.S. Bureau of Reclamation, to improve our understanding of habitat quality, the influence on various landscape features on ecosystem function, and the effects of restoration actions in the Sacramento–San Joaquin Delta. These data are intended for science researchers, students, policy makers, and the general public.
