| Authenticate and initialize the Earth Engine connection. | |
| Usage | |
| ----- | |
| 1. Put your project ID in config.py (GEE_PROJECT). | |
| 2. Run once to authenticate (opens a browser / pastes a token): | |
| python auth_setup.py | |
| 3. Thereafter, every script just calls `init_ee()` from this module. | |
