Crowd-sourced collected building attributes of the Colouring Dresden project (from 06 March 2023 to 01 October 2023)

Abstract

The building attribute data was collected by citizens as part of the citizen science project “Colouring Dresden”. Main goal was to collect information about buildings (like building age, usage, number of storeys, roof shape etc.) in an interactive online map. Different action formats (like dialogue series, presentations, mapathons, hackathons, and monthly meetings) were organised to bring citizens into action and discuss building-related topics. Focus was the sustainable construction of buildings and the question how good current buildings of the city are prepared for natural catastrophes like floods, heavy rain incidents or heat stress. The project period was from October 2022 to September 2023 and the mapping platform was launched in March 2023.

The project is part of the international research network “Colouring Cities Research Programme” (CCRP) and the first local project in Germany. Colouring Dresden is currently coordinating the European Hub of CCRP.

The project was led by Leibniz Institute of Ecological Urban and Regional Development Dresden, Germany in cooperation with:

-          Sächsische Landesbibliothek - Staats- und Universitätsbibliothek Dresden (SLUB) - Regionalportal Saxorum

-          Bund Deutscher Architektinnen und Architekten (BDA)

-          Zentrum für Baukultur Sachsen (ZfBK)

-          Technische Sammlungen Dresden (TSD) / DLR_School_Lab TU Dresden

-          Zentralbibliothek der Städtische Bibliotheken Dresden (SBD)

Data description

The data contains several files:

Completeness:

Completeness of collected building attributes differs and depends on mapping activities of the Citizen Scientists from March to September in 2023. Completeness of automated linked attributes is 47.6% or more. Completeness of crowd-sourced attributes is up to 5.3%.

100.0%                 building_id; ref_toid; location_latitude; location_longitude; revision_id; size_height_apex

47.6%                   location_number; location_street; location_postcode; location_town

5.3%                      building_attachment_form

2.0%                      is_domestic

1.1%                      size_storeys_core

1.0%                      architectural_style; architectural_style_source; use_building_current

0.6%                      size_storeys_attic; size_roof_shape

0.3%                      use_building_origin

And more attributes

Up-to-dateness: the data extract is from 1st of October, 2023 and includes the collecting period from March to September in 2023.
