This dataset supports scenario analysis using a high-resolution (5m) land cover classification of three European cities: Paris Region (France), Aarhus Municipality (Denmark), and Grad Velika Gorica (Croatia). The scenarios are: current (baseline) land cover, and a created new land cover that meets the 3-30-300 rule for urban greening (Konijnendijk 2023). In the 3-30-300 scenario, every building has two or more tree raster cells within a 30 m buffer, every neighbourhood has 30% or more green and blue space cover within a 300 m buffer, and each building has an accessible green space of at least 1 ha within 300 m. This rule was applied to the urban footprint of each city. In Paris, this applied only to the four central départements and not the entire Paris Region, Île-de-France.

The full methodology behind the datasets is described in the following paper. This paper analyses the extent to which each city currently meets, and measures the land cover change required to meet the 3-30-300 rule. Please also cite this paper when using the dataset.

Original Data Sources

These layers are based on the high resolution land cover layers produced by Knopp (2021, 2022a, 2022b). For Paris, the baseline land cover was modified, using the 10 m land cover by Wu (2022), to reclassify trees to either coniferous or deciduous. 

Data

LC_Classification_Lookup_Table.docx

This word document is a lookup table for the baseline and 3-30-300 scenario land cover classification.

Baseline_and_3_30_300_HRLC_all_cities.zip

This file contains the baseline and 3-30-300 scenarios for Velika Gorica, Aarhus, and the four central départements of Paris Region (clipped to a 1km buffer). These files include all interventions from the 3-30-300 rule.

Original_and_Final_HRLC_3_30_300_Paris_Region.zip

This file contains the baseline and 3-30-300 scenario for the entire Paris Region only. Whilst there is land cover data for the entire Paris Region, the interventions from the 3-30-300 rule were only applied to the four central départements. This file has been uploaded separately because the file size is greater.
