The 6th International Workshop on Geospatial Humanities (GeoHumanities 2022) was held together with the 30th ACM SIGSPATIAL International Conference on Advances in Geographic Information Systems. Scholars in the humanities have long paid attention to spatial theory and cartographic outputs joining in the 'spatial turn' of the 2000s. Since then, new technologies and methods have led to the emergence of the Spatial Humanities. This field is constantly evolving and is looking to address questions related to space and place and is posing very interesting challenges including, for example, the identification and analysis of real, vague, and imaginary space in textual corpora. Within the field, different theoretical and methodological approaches are being now explored and used, including GIS, NLP, Deep Mapping, Computer Vision, and Qualitative Spatial Representation among others. Methods from the standard toolset of geographic information systems have been successfully employed to analyze the geographies of human cultures, both past and present, and to address research questions posed by humanities-based fields. However, many challenges persist in the application of more recent technical developments in the geographical information sciences, which have been showcased in venues such as ACM SIGSPATIAL. Following the success of the previous editions the GeoHumanities workshop continues to showcase research using geographic information systems and other spatial technologies in humanities research, placing a strong emphasis on new methodologies that apply or adapt recent technical developments. The GeoHumanities workshop is a venue for computational research on the cutting edge of spatial data creation, curation, analysis, visualization, and interpretation in the humanities. It brings together researchers and practitioners from sub-fields of computer science, geographical information sciences and the humanities whose work combines humanistic questions with computational spatial methods. The workshop supports interdisciplinary and often collaborative research that makes novel contributions to both the humanities and the sciences.
