Maps, mapping, and spatial understanding are central to many current projects in the humanities. Too often, however, the tools and approaches that facilitate spatial knowledge are limited to GIS and data analysis most useful to scientists and social scientists. Humanities researchers and teachers bring a range of other concerns to spatial data: to work smoothly with historical maps from other spatial traditions, to work in languages other than English, to incorporate a range of media, and to represent ambiguity just to name a few issues.
