}Choose the right tool
Choose great-circle tools for shortest spherical paths and rhumb tools for constant bearings. Spherical models differ from ellipsoidal survey calculations. Web-map tiles have latitude limits and grid bearings require a stated convergence convention.
Limitations and common mistakes
- Spherical Earth radius 6371.0088 km unless another radius is displayed. Not an ellipsoidal survey or real-time navigation service.
- Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
