Digital elevation models derived from UAV overflights of the fifteen NPP study sites at Jornada Basin LTER in 2019

This data package contains digital elevation models (DEMs) of each
of the 15 NPP study sites at the Jornada Basin LTER in southern New
Mexico, USA. The models were derived from raw images collected
during uncrewed aerial vehicle (UAV) overflight missions conducted
in late summer and early autumn of 2019 (1 overflight day per site).
For each site one or two missions were flown during an afternoon
using a DJI Phantom 4 UAV, and between 450 and 1300 12.4 megapixel
RGB images were captured. A subset of images captured at each site
were loaded into Agisoft Metashape software to derive digital
elevation models using a structure from motion method. These models
include elevations of vegetation and other aboveground features. The
raw images are not provided but can be made available via project
PIs. This data package includes one centimeter resolution DEMs of
all 15 sites as geotiff raster files. Other derived products from
these UAV missions, including orthomosaic photos, digital terrain
models, and sparse point clouds, are available in other EDI data
packages (knb-lter-jrn.210543001, knb-lter-jrn.210543003, and
knb-lter-jrn.210543004, respectively). This study is complete.
