A mapping company Esri has used satellite images and mapping software to determine where the green space or vegetation was in each city.

.

Experts used the Normalised Difference Vegetation Index (NDVI) to calculate the percentage of green space in each city. The index uses the visible and near-infrared bands of the electromagnetic spectrum to assess whether land mass contains live green vegetation or not.

New images from mapping company Esri UK revealed that Edinburgh has the highest percentage of green space with 49 per cent, followed by Glasgow with 32 per cent, then Bristol at 29 per cent green space. Some cities in the UK are three times greener than others.

Greater London comes in at number 5, with 23 per cent of green space, shown by the bright green sections on the map.

However this technology is usually used to monitor drought, predict farming output or to help predict hazardous fire zones, the NDVI is used for global vegetation monitoring because it helps compensate for changing illumination conditions, surface slope, aspect and other unrelated factors.
