Round 1
Reviewer 1 Report
I wish to submit review for article entitled Coastal dynamics analysis based on orbital remote sensing big data and multivariate statistical models for consideration to Remote Sensing.
1. there is a stop point at the end of title. Please remove it.
2. there is error in the first author names and related affiliation.
3. The abstract is general and organized non-academically. Please rewrite it academically. Please Consider an abstract a 5-part structure consisting of 1) introduction, 2) problem/objective, 3) “Here we show”, 4) main results & conclusions, and 5) implications. One or two sentences providing a basic introduction to the field, comprehensible to a scientist in any discipline. Two to three sentences of more detailed background, comprehensible to scientists in related disciplines. study. One sentence summarizing the main result (with the words “here we show” or their equivalent).
4. The introduction needs to have some sentences about filling the knowledge gap, problem statement, and hypotheses for solving the problems, and also the main objectives of the study must be defined. It problem statement is very simple; which dataset should be adopted to fulfill proper and adequate outputs? Please provide motivation and justification as to why they are doing the investigation? The whole idea of writing this section is to cover two important questions—“What are the gaps present in the current literature?” and “Why is the current study important?”
5. Two first paragraphs of the introduction need to be updated to recent publication in the field.
6. I observed whole of introduction needs to be updated to recent publications (2020-2023) in the field.
7. Please replace the figure 1 with colorful and high resolution version.
8. Line 114, vegetated has different format and size. Please edit it.
9. Please provide a flowchart of the methodology outline all stages applied in this research. A flowchart of the methodology is required to show an overview of your study to the readership.
10. Line 190 and 198, formula and link has different format and size. Please edit it.

Reviewer 2 Report
This study analyzed the São Paulo coastline using satellite imagery over a 36-year period (1985-2021). Findings revealed an average erosion rate of -0.17 m, predominantly in a southeastward direction. The southernmost section experienced moderate and positive shoreline change, while erosion worsened from C2 to C6. The orientation of the beach face did not show a significant association with shoreline change rates, but dissipative beach faces had a relationship with moderately and highly aggregated transects. The configuration of the coastline, with a southwest-northeast orientation, makes southeast-facing beach areas more susceptible to erosion from storm waves originating in the southern quadrant.
The questions are
1. What is the novel scientific result of this manuscript
2. Where dataset could be found to reproduce research?
3. Why do you use satellite images instead of aerial photographs that can have a much better resolution?
Wrong usage of present and past sentences of the verbs.

Reviewer 2 Report
After the revision, the manuscript has a significant problem - data transparency.
The authors said, "This is accomplished through free, open-access computational platforms (e.g., Google Earth Engine - GEE)."
Sure, I agree, but the authors must publish the data sets they derive from GEE in open access. Nobody has time to dig GEE, the authors did it, please provide this data on zenodo.
