Konya: land change, 2016–2025
Two Sentinel-2 satellite images of a 20 km square around Konya, from 2016-07-31 and 2025-07-19, 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
- 2016-07-31
- After
- 2025-07-19
- Area analysed
- 391 km²
Change
+49.1 km²net change in built-up area
In cells the model is sure of on both dates (confidence ≥ 0.8): 24.6 km² became built-up, 32.8 km² changed in total.
Land cover on both dates
| 2016 | 2025 | ± | |
|---|---|---|---|
| Agriculture decreased | 43% | 26.2% | -16.8 |
| Natural vegetation increased | 9.2% | 13.4% | +4.2 |
| Built-up increased | 47.8% | 60.4% | +12.6 |
| Water no notable change | 0% | 0% | 0 |

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.
