Digital History involves using digital tools, technologies, and methods to research, analyze, present, and preserve the past. It combines historical scholarship with digital tools to enhance both the study and public engagement with history.
VIEWSHED ANALYSIS:
Viewshed analysis is a geographic information system (GIS) program that helps determine the areas that could be visible from a certain point on a landscape based on elevation and terrain data. It factors in geographic changes and industrial changes.
This tool is used within Historical studies to help reconstruct different historical perspectives. 500 years after an event, a building may no longer be standing, but we can know exactly what they were seeing way back when. In terms of Digital Humanities, viewshed analysis helps to understand the human perspective from different points in time
