Knowledge-Based Identification of Urban Green Spaces: Allotments

Urban Farm DB summary

Allotment gardens, a type of Urban Green Space (UGS), offer environmental, social, and health benefits but are often not recognized as a distinct category in land use maps due to their specific characteristics. This research proposes an identification approach utilizing semantic features such as the presence, density, and height of garden huts, proximity to water bodies and railroads, and the presence of pathways. The three-step workflow, combining a Random Forest classifier, hut extraction, and density-based clustering, accurately identified 78% of allotments in Augsburg and 88% in Wuerzburg.
