Geospatial technologies, which include application-based GIS systems, webmapping, and spatial network analysis, are used to define spatial relationships, both in relative terms and in with regards to their absolute position on the planet's surface.
Benefits
- The ability to compare independently produced datasets; offer topographical, environmental and political context; produce compelling and informative visualizations at a range of scales
- Potentially relate a historically remote period or even fictional events to the user's experiential knowledge (e.g. 'Sherlock Holmes' London').
- The interactive nature of digital media also allow for a much greater range of complexity to be managed, manipulated and viewed than is possible with paper maps.
Specific challenges
- The need to reduce complex real-world phenomena into simplified sets of abstract symbols
- The application of spherical co-ordinate systems to a planet that does not perfectly conform to them
- The projection of 3-dimensional data onto a planar surface (whether a printed map or a computer monitor)
In addition to these, the Digital Humanities considers such approaches as they apply to humanistic questions - how can they be used with incomplete, uncertain, contested and conflicting data? How might qualitative attributes such as emotional or political sentiment be captured? And how do we present results in a manner that conveys our conclusions, without eliminating important nuances, to an audience that may be unfamiliar with them?
