KML Polygon Extractor

This tool is designed to extract polygon coordinates from KML files. KML (Keyhole Markup Language) files are XML-based and often used for geographical data. This script parses these files to find and extract coordinates of enclosed polygons, particularly useful for polygons drawn in Google Earth.

Features

• Extracts coordinates of polygons from KML files.
• Outputs coordinates as a JavaScript variable.
• Automatically copies the output to the clipboard for easy use.

Installation

1. Clone this repository. git clone https://github.com/patpragman/shapefl.git and navigate to the newly created directory
2. Create a virtual environment named venv on linux: python3 -m venv venv.
3. Install the required dependencies. pip install -r requirements.txt

Usage

Run the script using the following command:

source geoconf.bash --input_file /path/to/kml_file.kml

The script will output the coordinates as a JavaScript variable and copy them to the clipboard.

Example Output

var roi = ee.Geometry.Polygon([  [[-122.45, 37.74], [-122.45, 37.8], 
   [-122.4, 37.8], [-122.4, 37.74], [-122.45, 37.74]]
]);

Limitations

The script is designed for simple polygons. It might not work as expected with complex topologies.
