The process of the semi-automated scoring of urbanization
The ‘UrbanizationScore’ software generates semi-automated scores of habitat urbanization based on the method by Czúni et al. (2012). In short, it takes a 1 km2 area around each location of selected geographical coordinates, downloads the respective aerial images from GoogleMaps, and scores the abundance of vegetation, buildings and paved roads within each 100×100m cell of each image. These scores are then used for calculating landscape-cover variables which are then combined by principal component analysis (PCA) into a score of urbanization for each area. This urbanization score ranks the study areas along the urbanization gradient objectively yet similarly to the ranking by human observers. For more detail, see Liker et al. (2008).
The software has been developed in the Image Processing Laboratory at the University of Pannonia.
