1.8 Information about funding sources that supported the collection of the data

The activities of the Rbanism community, including the preparation of this dataset, were supported by the the Netherlands eScience Center, the Mainstreaming Open Science Fund of the Open Science Community Delft, and the Department of Urbanism at TU Delft.

2. METHODOLOGICAL INFORMATION

2.1 Research questions, methods and envisioned uses

The dataset is designed to support the Geospatial Data Carpentry for Urbanism, which aims to teach participants how to work with geospatial data in R, specifically in the context of urban studies.

The dataset is structured to facilitate hands-on learning and practical applications of geospatial analysis techniques.

2.2 Methods for processing the data

• Raster data was processed using the terra package in R.
• Vector data was processed using the sf package in R.
• Data was cleaned and transformed using the dplyr and tidyr packages
• Data visualization was performed using the ggplot2 package.

2.3 Instrument- or software-specific information

• The workshop uses R as the primary programming language for data analysis and visualization.
• The dataset is compatible with R version 4.4.0 and above.
• The following R packages and libraries are required for the carpentry:
  • GDAL, GEOS, and PROJ.4
  • tidyverse v.2.0 for data manipulation and visualisation
  • terra v.1.7 for handling spatial raster data
  • sf v.1.0 for handling spatial vector data
  • leaflet for interactive maps
  • osmdata for accessing OpenStreetMap data
