The Semantic Segmentation Map Dataset (Semap) contains 1,439 manually annotated map samples. Specifically, the dataset includes 356 image patches from the Historical City Maps Semantic Segmentation Dataset (HCMSSD, [1]), 78 samples extracted from 19th-century European cadastres [2–4], three from Paris city atlases [5], and 1,002 newly annotated samples, drawn from the Aggregated Dataset on the History of Cartography (ADHOC Images, [6]).
Additionally, it comprises 12,122 synthetically generated image samples and corresponding labels.
Both datasets are part of R. Petitpierre's PhD thesis [7], and related paper [8]. Extensive details on annotation and synthetic generation procedures are provided in that work.
