Data and codes used for the field study regarding the rod float trajectories conducted in the Satsunai River on June 20, 2023.

This repository contains the data and code used for the field study regarding the rod float trajectories conducted in the Satsunai River on June 20, 2023. The files and directories are described as follows: marker.exe: Win64-complied application software file for manually inputting the float location and converting the location in the physical coordinate system. marker.pdf: The manual of the above application software. 1_Cams.zip: Three folders in the zipped file. Each folder contains a movie and float trajectory data of the surface tracers dropped at 15 points. 2_Colab Notebooks.zip: A zipped file contains Python code processing the data from three cameras and provides the trajectory of the maximum likelihood location of each drop. The directory also includes used data files. 3_Post processes.zip: A zipped file contains all trajectories obtained above are summarised into one file for drawing plots with GIS.
