Upcoming Contributions#

  • [Topic: Digital Landscape Traces] - Alexander Dunkel (IOER) & Dominik WeckmĂĽller (TU Dresden)
    To support transformative governance and planning, this interactive chapter will explore a privacy-safe dataset of 66 million social media posts (Dunkel and Nieswand 2025) published in the ioerDATA to map patterns of visitor frequentation for selected regions and areas in Germany (see Dunkel et al. 2025). Responding to direct feedback from planning offices and stakeholders, the notebook will provide an accessible approach to filter, subset, and visualize digital attention in physical spaces. The goal is to help planners identify spatial pressures and inform sustainable regional development.

  • [Topic: Story Map Hidden Herons in Urban Spaces] - Gongmingyue Tang (IOER) To support biodiversity-sensitive urban planning and knowledge transfer, this interactive StoryMap will use herons as a narrative lens to connect bird occurrence data with urban spatial datasets from IOER Monitor and ioerDATA. The chapter will introduce selected heron species in Germany and explore how water bodies, impervious surfaces, and urban tree canopy may provide and shape hidden habitats within cities. With a particular focus on the Canopy Height Model, the project will translate spatial data into an accessible map-led story about urban biodiversity, green infrastructure, and ecological niches. The chapter will demonstrate the process of turning selected spatial datasets into a data story, from choosing and linking relevant data layers to shaping them into an accessible narrative for public communication.

  • [Topic: Settlement Monitoring] - Oliver Harig
    IBTool is an open-source QGIS plugin that automatically derives settlement boundaries from building footprints and street networks (see Harig et al. 2021). It replaces manually digitised or administratively defined delineations with a consistent, data-driven delineation of the inner zone (§ 34 BauGB). Practical applications include settlement-area monitoring, assessing infill-development potential, and documenting land consumption — scalable from the municipal to the nationwide level. A recent expert evaluation (Eichhorn et al. 2025) found IBTool’s delineations more precise and consistent than comparable products such as ATKIS®-Ortslage and GHSL, with notably less over-detection at settlement edges. To support practical use, I will contribute tutorials covering the application of the tool as well as guidance on data preparation.
