When plotting WSE along the length of the channel, the data points appear to be clustered around the reach outlet. This doesn't appear to be correct and I believe this is because we're using the incorrect KaRin variable for the x-axis. Currently SWOT Viz is using node_dist, which is the "Mean distance between the observed node locations and the node locations in the PRD." Instead we should be using p_dist_out on the x-axis: "Along-stream distance from the reach center to the outlet, from the PRD."
When doing so, our plots transform from this:
to this:
Moreover, this can be converted into length along the channel by making the x-axis relative to channel length instead of distance to outlet:
