This data repository makes available accessibility indicators from populated 1km EU grid to towns and cities at aggregated scales (NUTS, EU reference grid cells). It covers all Europe and is based on the outputs of data previously processed and documented in another Zenodo repository. All the data sources, data processing and general objectives are described in this resource. A dedicated notebook and a reamde document in the root of the archive shows how this information has been aggregated at upper spatial/territorial levels, using geometric and statistical attributes associated to 1km grid cells (spatial position, population evolution, DEGURBA categories). These outputs are more suitable for analytical purposes at NUTS level (combination to other classical socio-economic indicators) or web mapping. Based on the data included in this repository and the GridViz JavaScript library, a visualization tool has been developed by RIATE. It proposes in an interactive way the 33 consolidated accessibility indicators to EU towns and cities. The source code is available in this Gitlab repository.
