| Landsat 5 TM Collection 1 Level 1 | landsat_tm_c1 |
| Landsat 5 TM Collection 2 Level 1 | landsat_tm_c2_l1 |
| Landsat 5 TM Collection 2 Level 2 | landsat_tm_c2_l2 |
| Landsat 7 ETM+ Collection 1 Level 1 | landsat_etm_c1 |
| Landsat 7 ETM+ Collection 2 Level 1 | landsat_etm_c2_l1 |
| Landsat 7 ETM+ Collection 2 Level 2 | landsat_etm_c2_l2 |
| Landsat 8 Collection 1 Level 1 | landsat_8_c1 |
| Landsat 8 Collection 2 Level 1 | landsat_ot_c2_l1 |
| Landsat 8 Collection 2 Level 2 | landsat_ot_c2_l2 |
| Sentinel 2A | sentinel_2a |
