  i. The importance of or motivation for the research.

  ii. The issue/argument of the research.

  iii. The methodology.

  iv. The result/findings.

  v. The implications of the result/findings.

2.       Explain the motivation pin points to make them understandable for readers. It is bit confusing. Rewrite the motivation point if possible.

3.       It is recommend to add a detailed system process flow of the proposed methodology.

4.        Verify all equations if they are added correctly.

5.       Figure of proposed model need refinement try to sketch neatly.

6.       Authors should add an algorithm to explain the proposed work and explain it in the proposed work section extensively.

7.       Is the proposed system secure enough and sustainable to apply in distributed environment? If yes, kindly approach with the below work and preferably include in the related work

Author Response

Dear reviewer,

We kindly appreciate all Your valuable comments and updates which were considered. The article was updated based on your suggestions.

In steps:

1.      The abstract is long and NOT satisfactory. It should contain the following parts:

• Abstract was rewritten and updated with all missing parts

2. Explain the motivation pin points to make them understandable for readers. It is bit confusing. Rewrite the motivation point if possible.

• The motivation was updated in the Abstract, and introduction and is also described in the aims of the proposed work

3. It is recommend to add a detailed system process flow of the proposed methodology

• Fig 3 describing process flow was updated (see line 208)

4.        Verify all equations if they are added correctly.

• The equation from (Maděra et al. 2019) is verified and correct

5.       Figure of proposed model need refinement try to sketch neatly.

• updated by Fig. 3 (see line 208)

6.       Authors should add an algorithm to explain the proposed work and explain it in the proposed work section extensively

• The abstract, introduction, and methodology were updated to extensively explain the proposed work.

7.       Is the proposed system secure enough and sustainable to apply in distributed environment? If yes, kindly approach with the below work and preferably include in the related work

• The distributed environment of servers in our department was partially used during the processing of aerial images to enhance the processing time of large-scale data. Deep learning methods of image classification were not tested and included in the data processing. Thanks to the crown shape specification of interested Dragon trees, outputs of used object-based classification provided satisfying outputs. For a further inventory of other Dracaena species, we believe that mentioned deep learning methods provide a valuable analytical solution. Also, Large-Scale Data Streaming, Processing, and Blockchain Security were not used in the proposed study.

Reviewer 2 Report

1.In the method section, it's better add a flowchart of the method, which will show all the main steps involved in this paper.

2.In Equation (1), the authors used the crown sizes to estimate the spatial age distribution of the Firmihin dragon tree forest. How about the accuracy?

3.In Line 215, the authors added a linear vector layer for each dead tree. How to realize this? Pls describe this step in detail.

4.In figure 5, how to set the grid size? In other words, how to set the image resolution.

Dear reviewer,

We kindly appreciate all Your valuable comments and updates which were considered. The article was updated based on your suggestions.

In steps:

"1.In the method section, it's better add a flowchart of the method, which will show all the main steps involved in this paper."

• A flowchart describing all steps of the methodology was added as Figure 3 (see line 209), all other figure numbers were updated

"2.In Equation (1), the authors used the crown sizes to estimate the spatial age distribution of the Firmihin dragon tree forest. How about the accuracy?"

• The accuracy of the age equation is based on methods published by (Maděra et al 2019, and Adolt et al. 2012) which we adopted. It was better described by updated methodology (see lines 203 - 207)

"3.In Line 215, the authors added a linear vector layer for each dead tree. How to realize this? Pls describe this step in detail."

• Each dead tree was vectorized manually from the root section to the crown section. Such a process is described in the methodology (see lines 215 - 219)

"4.In figure 5, how to set the grid size? In other words, how to set the image resolution."

• Grid size (spatial resolution) is 1 hectare. This is described in figure headings and in methodology (see line 238)
