Introduction
KML (Keyhole Markup Language) files are a popular format for displaying geographic data in mapping applications like Google Earth and Google Maps. If you need to quickly generate circular or square areas around a specific center point, the "KML Circle & Square Generator" is an excellent online tool for you. This tool not only generates KML but also offers the convenience of exporting the generated coordinates to an Excel file. In this blog post, we'll provide a step-by-step guide on how to use this tool.
You can find the tool here: https://kmlcirclegenerator.blogspot.com/
Key Features of the Tool:
Shape Selection: Option to create either a Circle or a Square.
Customization: Define center latitude, longitude, size (radius or side length), and unit (km, meters, miles, feet, nautical miles, yards).
Precision Control: Control the smoothness of the shape by selecting the Number of Points for the perimeter.
Styling: Change line color, polygon fill color, and fill opacity.
Geometry Type: Options to generate KML as MultiGeometry (filled with outline), Polygon (filled with outline), or LineString (outline only).
Document & Placemark Naming: Custom names for the KML document and placemark, which automatically update based on the selected shape and point count.
Output:
Generated KML code is displayed in a textbox.
Option to copy the KML code.
Option to download the KML file (.kml).
Option to download the latitude and longitude of the shape's vertices into an Excel (.xlsx) file.
Bilingual Interface: Uses both Bengali and English labels.
How to Use: Step-by-Step Guide
Access the Tool: First, navigate to this link in your web browser: https://kmlcirclegenerator.blogspot.com/
Select Shape Type:
From the dropdown menu, choose either "(Circle)" or "(Square)".
Upon selection, the "(Radius)" label will change to "(Side Length)" for squares. The "Document Name" and "Placemark Name" will also update automatically.
Enter Document Name:
Provide a suitable name for your KML file. By default, it will suggest a name based on the selected shape and number of points (e.g., "KML Circle Output (1000 Points)").
Enter Center Coordinates:
In the "(Center Latitude)" and "(Center Longitude)" fields, enter the decimal degree values for your desired center point.
Define Dimension & Unit:
Dimension: If you selected a circle, enter the "āĻŦ্āĻ¯াāĻ¸াāĻ°্āĻ§ (Radius)". If you selected a square, enter the "(Side Length)".
Unit: Select your preferred unit (e.g., km, m, miles, etc.) from the dropdown.
Select Number of Points for Perimeter:
From this dropdown, choose how many points will be used to construct the perimeter of the shape. More points result in a smoother shape (especially for circles). The default and recommended value is 1000 (for High Precision). Changing this value will also update the "Document Name" and "Placemark Name".
Enter Placemark Name:
Give a name for this specific shape within the KML file. This will also auto-update.
Define Color & Opacity (āĻ°āĻ āĻāĻŦং āĻ āĻĒাāĻ¸িāĻি):
Line/Outline Color (āĻ˛াāĻāĻ¨েāĻ°/āĻāĻāĻāĻ˛াāĻāĻ¨েāĻ° āĻ°āĻ): Use the color picker to select the outline color for your shape.
Polygon Fill Color (āĻŦāĻšুāĻুāĻেāĻ° āĻĢিāĻ˛ āĻ°āĻ): Use the color picker to select the fill color for the interior of the shape.
Polygon Fill Opacity (āĻŦāĻšুāĻুāĻেāĻ° āĻĢিāĻ˛ āĻ āĻĒাāĻ¸িāĻি): Use the slider to adjust the fill color's transparency (from 0.0 to 1.0). 0.0 means fully transparent, and 1.0 means fully opaque.
Select Geometry Type:
MultiGeometry: This is the default and recommended option. It creates both a filled shape and its outline.
Polygon: This creates a filled shape and its outline.
LineString: This creates only the outline of the shape, with no fill color.
Generate KML:
After filling in all the inputs, click the "(Generate KML)" button.
The generated KML code will appear in the textbox below.
Using the Output:
Copy KML: Click this button to copy the entire KML code from the textbox to your clipboard.
Download KML File: Clicking this button will download a .kml file, which can be opened in Google Earth or other mapping software. The filename will be taken from the "Document Name" field.
Download Excel: Clicking this button will download an .xlsx Excel file. This file will contain "Vertex_ID", "Latitude", and "Longitude" columns for each vertex of the shape. The filename will indicate the shape type and number of vertices (e.g., "Circle_Coordinates_(1000_Vertices).xlsx").
Important Note:
The tool uses a spherical Earth model for calculations. For larger distances, there might be slight differences compared to tools using more complex ellipsoidal models (like WGS84).
Conclusion
The "KML Circle & Square Generator" is a very user-friendly and effective tool that helps you quickly create customized KML shapes. The Excel export feature makes it even more useful for data analysis and other GIS tasks. We hope this guide helps you use the tool effectively. Happy mapping!
