Cartographic Sign Detection Dataset (CaSiDD)

<<< This dataset is not released yet. Release date: 1st September, 2025. >>>The Cartographic Sign Detection Dataset (CaSiDD) comprises 796 manually annotated historical map samples, corresponding to 18,750 cartographic signs, like icons and symbols. Moreover, the signs are categorized into 24 distinct classes, like tree, mill, hill, religious edifice, or grave. The original images are part of the Semap dataset [1].The dataset is published in the context of R. Petitpierre's PhD thesis: Studying Maps at Scale: A Digital Investigation of Cartography and the Evolution of Figuration [2]. Details on annotation, and statistics on annotated cartographic signs are provided in the manuscript.Organization of the dataTo come soon.Descriptive statisticsNumber of distinct classes: 24 + hapaxesNumber of image samples: 796Number of annotations: 18,750Study period: 1492–1948.Use and CitationFor any mention of this dataset, please cite :@misc{casidd_petitpierre_2025,  author = {Petitpierre, R{'{e}}mi and Jiang, Jiaming},  title = {{Cartographic Sign Detection Dataset (CaSiDD)}},  year = {2025},  publisher = {EPFL},  url = {https://doi.org/10.5281/zenodo.16278381}}@phdthesis{studying_maps_petitpierre_2025,  author = {Petitpierre, R{'{e}}mi},  title = {{Studying Maps at Scale: A Digital Investigation of Cartography and the Evolution of Figuration}},  year = {2025},  school = {EPFL}}Corresponding authorRémi PETITPIERRE - [email protected] - ORCID - Github -  Scholar - ResearchGate Work ethics85% of the data were annotated by RP.
