## Introduction

In this article, we will compare different Python tutorials on how to calculate the polygon area on Earth’s surface. This is an important task in both GIS and remote sensing, especially for measuring land use and land cover changes over time. We will analyze the differences and similarities between each tutorial and provide our opinion on which Python tutorial is the best for calculating the polygon area on Earth’s surface.

## The Tutorials

### Tutorial 1: How to Calculate Polygon Area on Earth’s Surface with Python

The first tutorial we will analyze is from RealPython.com. This tutorial covers the basics of using Python to calculate the polygon area on Earth’s surface. It shows how to use the shapely and pyproj libraries to accomplish this task. This tutorial also provides a good introduction to coordinate reference systems (CRS).

### Tutorial 2: Calculate Polygon Area on Earth with Geopandas and Python

The second tutorial we will analyze is from Towards Data Science. In this tutorial, the authors show how to use Geopandas and Python to calculate the polygon area on Earth’s surface. This tutorial is more advanced than the first one, as it requires a basic understanding of GIS data formats and operations. It utilizes the Fiona library to read and write GIS data and the Geopandas library to perform the actual calculations.

### Tutorial 3: Calculate Area and Perimeter of Polygon with Python and Geopy

The third tutorial we will analyze is from the GeeksforGeeks website. In this tutorial, the authors show how to use Python and the Geopy library to calculate the area and perimeter of a polygon on Earth’s surface. They also explain the Haversine Formula, which is used to calculate distances on a spherical surface. This tutorial is a good introduction to using Python for spatial analysis.

## The Comparison

### Libraries Used

Tutorial 1 uses the shapely and pyproj libraries, tutorial 2 uses the Geopandas and Fiona libraries, and tutorial 3 uses the Geopy library. All three libraries are commonly used in GIS and remote sensing applications. However, Geopandas is a more advanced library that provides a lot of powerful tools for working with GIS data, while shapely and Geopy are more specialized libraries for specific tasks.

### Difficulty Level

Tutorial 1 is the easiest tutorial to follow, as it provides a step-by-step walkthrough of the process with lots of explanations. Tutorial 2 is a bit more complicated, as it requires some basic knowledge of GIS data formats and operations. Tutorial 3 is the most challenging, as it involves using a formula to calculate distances on a spherical surface.

### Output Format

Tutorial 1 outputs the result as a simple number, tutorial 2 outputs the result as a shapefile or GeoJSON file, and tutorial 3 outputs the result as a dictionary. The output format depends on the end use of the calculation. If the result is being used for further analysis, a file format such as shapefile or GeoJSON would be appropriate. If the result is being used for a web application or presentation, a simple number or dictionary might suffice.

### Efficiency

Tutorial 1 is the least efficient, as it requires looping through all the vertices of the polygon. Tutorial 2 is more efficient, as it uses the shapely and fiona libraries to perform the calculations directly on the GIS data. Tutorial 3 is the most efficient, as it uses an optimized formula to calculate the area and perimeter directly.

## Our Opinion

After analyzing and comparing the tutorials, we believe that tutorial 2 is the best for calculating the polygon area on Earth’s surface. It provides a good balance between ease of use and power, with the Geopandas library providing a lot of powerful tools for working with GIS data. The output format is also flexible enough to suit different needs. However, all three tutorials are excellent resources for those looking to learn how to calculate the polygon area on Earth’s surface with Python.

## Conclusion

In this article, we compared three Python tutorials on how to calculate the polygon area on Earth’s surface. We analyzed the differences in libraries used, difficulty level, output format, and efficiency. We also provided our opinion on which tutorial is the best for this task. Ultimately, it depends on the end use of the calculation, but all three tutorials are great resources for learning how to use Python for spatial analysis.
