Round 1

Reviewer 1 Report

This paper was focused on the water quality assessment of four lakes of South China University of Technology, unmanned aerial vehicle (UAV) with multispectral camera and in-situ measurement of the comprehensive trophic level index (TLI) were all conducted. Three machine learning algorithms (XGB, RF, and ANN) are applied to construct the inversion model between multispectral data and observations to further provide a practical framework to estimate water quality. The result and discussion of this study was is of some novelty. A minor revision was suggested as feedback. The author still needs to improve the quality of this paper on these following aspects shown below.
The data and season of the field sampling
What is the reference for the quantification of Trophic State with the lack of ????? data in study?
The conclusion can be summarized more streamlinedly.

Reviewer 2 Report

The following are my comments:

- The Abstract section is too long. Please remove unnecessary text.

- The novelty of the work has to be better shown. In the current form, the focus is on just different methods used and already developed in the literature. In other words, what problem did you solve?

- Add some discussion on the shortcomings of your proposed methods and how to solve them.

- You may find the following papers useful to improve the quality of your manuscript:
