Video Globe Challenge 2020 dataset

############### DATASET OF THE VIDEO GLOBE CHALLENGE 2020 ############### ## Article ## "Quantifying and reducing the operator effect in LSPIV velocity and discharge measurements", 2023, Bodart G., Le Coz J., Jodeau M., Hauet A. ## Short presentation ## The Video Globe Challenge 2020 [Le Coz 2021] is a video gauging intercomparison carried out during the COVID-19 lockdown of spring 2020. It involved 22 to 26 participants using various image-based techniques to determine discharge on 8 videos. The videos are representative of the diversity of river gauging conditions and imaging viewpoints. Each video come with a discharge reference and associated uncertainty. ## Files ## - Video_Globe_Challenge_2020.xlsx -> All the results of the Video Globe Challenge, as processed -in French- by Le Coz et al.
