Resumé

Klimaforandringer skaber udfordringer og øgede risici i byer, hvilket nødvendiggør hurtig tilpasning uden at føre til stiafhængighed. Derfor rettes mere opmærksomhed mod naturbaserede tilgange, hvor bytræer har stort potentiale ved at levere klimaregulerende økosystemtjenester. Imidlertid er tilgængelige hyperlokale geodata og kort over urbant trækronedække (UTC) i øjeblikket utilstrækkelige, og lovende AI-baserede kortlægningsmetoder er ofte komplekse og kræver særlige kompetencer. Tilsammen udfordrer det særligt små byer, som ofte har færre ressourcer.

Dette studie demonstrerer for den mindre danske by, Randers, hvordan UTC-dække effektivt kan kortlægges ud fra danske geodata ved hjælp af simple GIS-teknikker som et simplere alternativ til AI-baserede modeller. Den udviklede model præsterer lovende med høj geospatial nøjagtighed og giver dermed værdifuld rumlig information og lokale UTC-baselines kommunikeret visuelt via kort.
