Sentinel-2 NDWI (10 m)

Satellite rasters

Water/moisture index at 10 m — identifies cooling water bodies and moist surfaces. Use this as a citywide satellite backdrop — helpful for seeing fine-grained patterns behind neighbourhood averages.

What it shows

Normalized Difference Water Index. Blue/green (NDWI > 0) = open water or saturated soil. Brown (NDWI < −0.3) = dry, built-up surfaces. Water bodies act as urban cooling sinks; visualize their extent at higher resolution.

Data sources

Sentinel-2 L2A Green (B3) and NIR (B8) bands at 10 m, median composite, cloud-masked.

How it was prepared

Satellite scenes are filtered for cloud and quality issues, converted to the mapped indicator, and published as map tiles clipped to Zagreb.
