Step 1: Select stationary and moving plates (use 'xx' for fixed NNR frame).

Fixed plate: Enter two-letter code from list above -

Moving plate: Enter two-letter code from list above -


Step 2: Input coordinates for velocity calculation.

Type or cut-and-paste latitude, longitude pairs in decimal or integer degrees,
one pair per line.

WARNING: Latitudes should be geocentric (spherical Earth) rather than geodetic.

Example 1: 45°N, 50°E should be entered 45, 50 or 45.0, 50.0
Example 2: 30.4°S, 120.6°W should be entered -30.4, -120.6
