The article introduces “historical GIS,” or Geographic Information Systems to provide statistical analysis’s of any work to study anything from the past. It is very useful in the function of digital history that allow historians to conduct research. For example, the GIS can create numerous detailed maps and tables to show exactly what a certain location looks like; this idea could be similar to Google Maps in that the viewer is capable of viewing roads and streams that surround it. The GIS can include data revolving on the data on weather, climate, and global patterns. This production of the GIS is very instrumental for historians and anyone else who is fascinated about learning about the world around them, the past, present, and future. I find this an interesting source of information that puts everything possible into one place.
