Environmetal layers of the street network of Tallinn

These datasets contain the spatial layers of environmental variables of the street network of Tallinn. They are the result of a research assessment conducted to evaluate the environmental quality of the Tallinn street network. Environmental layers have been assigned to each street segment using the Zonal Statistics tool within a 25-metre buffer zone from street segments.

The datasets are provided in the GeoPackage (gpkg) file format, ensuring compatibility with Geographic Information System (GIS) software and integration into existing spatial databases.

The datasets include the following environmental layers:

ndvi_segment_tallinn: This layer represents greenery for street segments derived from the Normalised Difference Vegetation Index (NDVI), ranging between 0 and 1, from 18th June 2021.

pm25_segment_tallinn: Annual PM2.5 (particulate matter with a diameter of 2.5 micrometres or smaller) mean street segment values for the year 2020.

pm10_segment_tallinn: Annual PM10 (particulate matter with a diameter of 10 micrometres or smaller) mean street segment values for the year 2020.

no2_segment_tallinn: Annual NO2 (nitrogen dioxide) mean street segment values for the year 2020.

noise_segment_tallinn: Mean noise (Lden) street segment values from the year 2019.

These datasets serve as resources for analysing and understanding the environmental characteristics of the Tallinn street network. Researchers and urban planners can utilise these data.
