High resolution aerial imagery of barley over a growing season

This dataset consists of unprocessed images and orthomosaic imagery of a barley field in Bozeman, Montana, collected throughout the growing season from emergence to maturity. The orthomosaics were used to develop an open-source workflow for extracting quantitative values from individual plots for downstream analysis of plant traits. This field exemplifies a challenge for plot extraction, as plots were planted with no border rows or alleys. ,
UAV Imagery Collection: 

Data was collected using a Mavic 2 Pro drone with the integrated Hasselblad L1D-20C RGB camera at an altitude of 90 feet (27.4 m). Flights were conducted over a barley field located west of Bozeman Montana (45.676415, -111.149092). DJI GS Pro software was used on an iPad mini to create an automated flight path for imagery capture.  Images were collected while hovering to minimize blurring and captured with 70% overlap along the flight path and 70% overlap between flight passes. Weather permitting, flights were timed as close to 10:00 am or 2:00 pm as possible.

OpenDrone..., Imagery can be previewed using any default Windows or MacOS program. The stitched orthomosaic TIFF files can also be previewed in any file viewer but are best viewed through a GIS program. The open-source GIS software QGIS is recommended.
