Mersin: land change, 2016–2025
Two Sentinel-2 satellite images of a 20 km square around Mersin, from 2016-07-28 and 2025-07-23, 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
- 2016-07-28
- After
- 2025-07-23
- Area analysed
- 385 km²
Change
0 km²net change in built-up area
In cells the model is sure of on both dates (confidence ≥ 0.8): 2.9 km² became built-up, 14.3 km² changed in total.
The model is undecided on this scene; treat the results with caution.
Land cover on both dates
| 2016 | 2025 | ± | |
|---|---|---|---|
| Agriculture increased | 10.2% | 17% | +6.8 |
| Natural vegetation decreased | 17.9% | 10.9% | -7 |
| Built-up no notable change | 33.3% | 33.3% | 0 |
| Water no notable change | 38.6% | 38.8% | +0.2 |

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; results outside Europe are less reliable.
- Clouds, shadows and seasonal differences can show change that is not there.
