Lost Cities: How Does GIS Help in Finding the Underground Surface?

If you research the details of the ancient cities today, you will find a wealth of information about different locations. This data dates back to hundreds of thousands of years ago. How do you think it has become possible for researchers and scientists to locate the historical data so effortlessly? Well, the credit goes to the GIS (geographic information system).

The technology can be used to not only fetch historical data, but it helps in analyzing and processing a large volume of information in the most efficient way. Take the Ancient Egypt Research Associates (AERA), for example. They have employed the GIS technology on the great pyramids of Giza to analyze and process 15 years of data. This information is shared with the archeological communities for further discussion and analysis.

Though archaeologists and researchers have found the technology quite useful in archaeology, they are working together to make the GIS model stronger and better. It contributes to modern geography by making it easier to update the map data and incorporate it into the geography. Gone are the days when the maps had to be drawn manually. The implementation of the geographic information system has automated the mapping process and has helped archaeologists discover many lost cities and information about the ancient structures.

The Ground-Penetrating Radar Technology

GIS uses ground-penetrating radar technology to expose the lost cities and collect data of the underground surface. Commonly known as the geophysical locating technique, the ground-penetrating radar employs radio waves that penetrate deep into the ground and click the photos of the surface below the ground without causing any damage to the land. That’s the specialty of this minimally-invasive image capturing technology.

It has made it easier for workers to highlight the underground location that has utilities without causing any significant damage to the surface. Antenna and transmitter are the two main devices used in the process of collecting the underground pictures in a minimally-invasive way and with accuracy. The question is what does the GIS and the ground-penetrating radar help you collect or what information does it obtain that can help archeologists in processing research?

Collection of Underground Data

Well, it can collect data about different items. The technology is employed in the areas where the archaeologists need to map the materials made of plastic, concrete, PVC, metal, and natural materials. The major purpose of implementing this technology is to locate the underground pipelines, variations in the ground strata, excavated regions, air pockets, bedrock, groundwater tables, and the list goes on.

The specialty of the GIS is that it collects this information without causing any damage to the surface or underground. Whether you need to know more about the excavated area or reveal the lost materials made of metal, plastic, concrete, and natural materials, the geographic information system can help you with all types of archaeology-related applications. Besides, it is absolutely safe to use the GIS application on the location sites.
