# How green is your street

See how much vegetation the satellite observed around addresses on your street on 22 August 2026. Search 3,830 Bucharest streets, then explore the 3D map.

On half of the 3,830 measured streets, under 25% of pixels are dense green. The median NDVI is 0.298; the dense-green threshold is 0.4.

The greenest street is Strada Tomis: 83% dense green, across 22 addresses. The greyest is Strada Constantin Bosianu: 0%, across 23 addresses. And Smârdan, in the Old Town, also 0%, across 72 addresses.

The numbers come from a single clear day, 22 August 2026. The satellite's green is vegetation's spectral signal, not counted trees: lawns and weeds read green, mineral plazas read grey.

## The city with all its green

Dense green are the 53 parks, each on its August value. Between them, the surface joins everything: every 200-metre cell carries the mean NDVI seen from space, from the grey of asphalt to the green of canopy.

This is all the green seen in one day: the height of the 53 parks shows the measured value, and the surface under them shows the NDVI. Colour says the band, height says how dense the green is.

Only the parks: 53 parks over 2 hectares, measured with the same ruler as the streets. Lakes are cut out, so they don't dilute the mean. The greenest of the large ones is Parcul Kiseleff, at 95% dense green.

For example, Șoseaua Mihai Bravu: NDVI 0.300, 31% dense green, from 1,007 clear pixels around 239 addresses. The nearest measured park, Parcul Național, is 1.1 km away.

Only the streets, through the surface: Strada Tomis is the greenest (83%, by Titan park), Smârdan the most famous grey one (0% across 72 addresses, stone on stone). Rankings keep only streets with at least 20 addresses.

Only the sectors: Sector 1 leads with 57% dense green, Sector 2 is last, at 37%. The Băneasa forest is in Sector 1 too.

## What the green means

NDVI is an index of red and infrared, between −1 and 1: asphalt sits below 0.2, dense vegetation passes 0.4. Every street, park and map cell is coloured by its mean; the bands are the same everywhere.

- **Grey** (under 0.2): Asphalt, concrete, roofs. Smârdan is here, at 0.037.
- **Pale** (0.2–0.3): Mineral with traces of green. The street median sits here, 0.298, with Mihai Bravu at 0.300.
- **Patchy** (0.3–0.4): A mix of yards, squares and houses.
- **Green** (0.4–0.5): Ordinary urban green; the mean alone doesn't say how many pixels are green.
- **Dense** (0.5–0.6): Closed canopy. Tomis is here, at 0.552.
- **Park-grade** (above 0.6): What the big parks see: Cișmigiu 0.657, Herăstrău 0.636.

A pixel is 10 metres: one pixel holds tree, lawn and pavement at once. That is why the page talks about green, not trees.

The 0.4 threshold is this analysis's cut: on this page, “dense green” means pixels with NDVI ≥ 0.4. Interpretation guides give wide bands, so every ranking sits beside the raw mean.

## How the number is made

Each street takes its green from around its addresses: 25-metre discs around every point in the index, clear pixels only, no clouds and no cloud shadows. The mean is mean NDVI; the share is the fraction of pixels above 0.4.

The day is 22 August 2026, a nearly cloud-free Sentinel-2 pass: 99.64% of pixels are clear. The bands used are red and near-infrared, at 10 metres; the cloud classification comes at 20 metres.

A street with under 3 addresses gets no number; rankings keep only streets with at least 20 addresses. 1,048 streets stayed unmeasured — they show as such, not as zero.

Limits: the satellite sees vegetation's signal, not trees — crops, lawns and weeds read green. A 10-metre pixel mixes everything it catches: tree, lawn, pavement. And it is a single August day: after a rainy week, the lawns would read differently.

## Parks and sectors

The 53 parks over 2 hectares, measured with the same ruler as the streets; lakes are cut out, so they don't dilute the mean. The area is the mapped polygon's, not the official one. Some are squares or neighbourhood greens, not big parks — the label comes from the map.

### Sectors

First comes Sector 1, at 57% dense green; last is Sector 2, at 37%. The Băneasa forest lies in Sector 1.
