GlobeVsFlat is an interactive tool that helps you understand the differences between a round Earth and a flat Earth. It uses maps, flight routes, distance calculations, and more to show how these models work. You can explore flight paths, map projections, and even see the Qibla direction to the Kaaba.
This tool runs in your web browser. It works on Windows and other operating systems without installing complicated software.
- A Windows computer running Windows 10 or later
- A modern web browser (Google Chrome, Microsoft Edge, Firefox, or Opera)
- Internet connection to load the app and map data
- Basic mouse and keyboard use
No additional programs or files are required beyond opening the app in your browser.
To get started, visit the GlobeVsFlat page below:
This link takes you to the main project page on GitHub. From here, you can open the web tool directly or download files if available.
- Open your web browser. Chrome or Edge works best.
- Click this link: GlobeVsFlat on GitHub
- On the GitHub page, look for the "Open in GitHub Pages" or similar button to launch the app.
- If the web app is not directly available, look for "Releases" or files to download the application.
- Download any files available, such as
.htmlor.zip. - If you download a
.zipfile, right-click it and choose "Extract All" to unzip the files. - Open the extracted folder and find the main
.htmlfile. Double-click it. This opens GlobeVsFlat in your browser. - You can now use the app to explore different Earth models and maps.
The app runs fully in your browser. No setup or installation needed beyond opening the file.
GlobeVsFlat shows you two views of the Earth:
- A 3D globe that looks like our real world.
- A flat map that represents the flat Earth model.
You can compare things like:
- Distance between two places.
- Flight paths between cities.
- Different map shapes created by projections.
- Direction to the Kaaba for prayer (Qibla).
Use the mouse to zoom or rotate the globe or flat map. Click on cities or points to see distances and routes.
-
Distance Calculations
GlobeVsFlat calculates straight-line distances as the crow flies on both Earth models. This lets you see how distances change depending on the shape of the Earth. -
Flight Paths
The tool draws flight routes between airports or cities. You can see curved flight paths on the globe, and how these change on a flat map. -
Map Projections
GlobeVsFlat uses several map projection techniques, including azimuthal projection. These change how the round Earth appears as a flat map. You can compare them. -
Qibla Direction
The app helps you find the correct direction to the Kaaba from any location, using geodesic calculations on the globe and flat Earth. -
Interactive Map Controls
Pan, zoom, and rotate the view with mouse controls. This makes exploring easy and intuitive.
- If the web page refuses to load, check your internet connection.
- Use a modern browser to avoid errors with 3D or map rendering.
- If you download a zip file, extract it before opening the
.htmlfile. - Allow the browser permissions for location if you want to use geolocation features.
- Refresh the page if the map does not show up correctly.
- Check for browser updates to keep all features working smoothly.
The GitHub page may include these types of files:
- HTML files: Open in your browser.
- JavaScript files: These run the app in the background.
- Data files: Contain information on cities, airports, and map shapes.
- Documentation: This README and other helpful notes.
You do not need to modify these files. Just open and explore.
Spherical Earth:
This is the real shape of the Earth, a sphere. Distances follow curved lines called great circles. Flights often take curved paths here.
Flat Earth:
This model shows Earth as a flat disk. Distances and directions are different here. GlobeVsFlat helps you see where this model produces errors or distortions.
The app combines geography, navigation, and math to show these differences clearly.
Can I use GlobeVsFlat offline?
Yes. Download the files and open the main .html file in your browser without internet. Some features like map tiles may need online access.
Is this tool accurate?
The tool uses standard formulas and data for distances and projections. It aims to give a good visual and numerical comparison.
Do I need to install anything?
No. GlobeVsFlat runs in the web browser without installation.
Can I use this on other systems?
Yes. GlobeVsFlat works on Linux, macOS, and mobile browsers.

GlobeVsFlat is open source and welcomes ideas or improvements. If you want to contribute, you can learn more on the GitHub page. For questions, check the issues or discussions sections.
GlobeVsFlat uses these technologies:
- React for user interface
- Cesium and Leaflet for maps and 3D globe
- Geodesy for distance and direction calculations
- Various map projection formulas to create accurate flat maps
The app covers topics like geography, cartography, flight routing, and navigation for a better understanding of Earth's shape.
