Delhi: land change, 2016–2025
Two Sentinel-2 satellite images of a 20 km square around Delhi, from 2016-06-04 and 2025-06-12, were classified by a ResNet18 model trained on EuroSAT. Every 640 m cell is put in one of four land-cover groups, and the two dates are compared cell by cell.
- Before
- 2016-06-04
- After
- 2025-06-12
- Area analysed
- 394 km²
Change
+54.1 km²net change in built-up area
In cells the model is sure of on both dates (confidence ≥ 0.8): 23.8 km² became built-up, 42.2 km² changed in total.
Land cover on both dates
| 2016 | 2025 | ± | |
|---|---|---|---|
| Agriculture decreased | 62.1% | 55.6% | -6.5 |
| Natural vegetation decreased | 11.9% | 4.4% | -7.5 |
| Built-up increased | 25.1% | 38.8% | +13.7 |
| Water no notable change | 0.9% | 1.2% | +0.3 |

Limits
- Every value shown is a model estimate, not a measurement.
- Areas are not measurements but approximations counted from cells. The figures are always computed on 640 m cells; the scale only changes how the map is drawn.
- The model was trained on European images only; results for places tagged "experimental" are less reliable.
- Clouds, shadows and seasonal differences can show change that is not there.
