Wheat video experiments 2000 data archive

Observations of wheat motion in wind were made through the later part of the growing season (June - August) for wheat on Cranfield Airfield in 2000. The data collected include stereo videogrammetric measurements of the motion of small targets attached to wheat plants along with simultaneous local wind velocity measurements. <div><br></div><div>This archive contains the main data files for each day of the experiments together with some documentation for the experiments. There should be enough information so that users can analyse the data for their own requirements. EACH DIRECTORY IS PROVIDED AS ONE ZIPPED FILE (E.G. docs.zip, validation.zip, 0602.zip, CREATED USING 7-ZIP, AN OPEN SOURCE PROGRAM AVAILABLE FROM WWW.7-ZIP.ORG). THE ZIPPED FILES SHOULD BE READABLE BY WINZIP, WINRAR, 7-ZIP AND SIMILAR PROGRAMS.<br><div><b><br></b></div><div><b>Experiment summary: </b>Experiments took place during the summer of 2000 on the dates in the following table.

Pre-processing has been carried out to synchronize the video and wind data, to obtain coherent trajectories for each target tracked, and to present the data in a common reference system. </div><div><b><br></b></div><div><b>Directory File Comments: </b></div><div><u>docs:</u></div><div>DVA data 2000 summary.xls - Summary of the anemometer data processing parameters and key results from the experiments </div><div>DVA data 2000.doc - Word document describing the digital vane anemometer (DVA) data processing sample video</div><div>DVA data.doc - Describes sample data for target trajectories and the wind data. </div><div>vidreport2.pdf - Technical report documenting the videogrammetry technique used to measure the target positions, calibrate the system, and form coherent trajectories. </div><div>Wheat video expts 2000.xls - Tabulates data to be used with...</div><div>Wheat video expts 2000.doc - Documents much of the data pre-processing to allow it to be repeated if necessary from the original video files.
