Geographic Text Analysis: How does GIS Help GTA?

GIS has always been associated with quantitative approaches ever since its inception, because of its ability to collect, process, analyze, and store quantifiable data in the most efficient way. The application of this modern technology kept growing, as the demand for spatial tools grew.

Researchers have started using the Geographic Information System for analyzing and processing a large volume of information related to the different locations. Not only has it helped researchers in collecting historical information with the help of remote sensors, but the technology has proven to be of great use for the archaeologists who need a smart censoring tool for the excavation sites. The technology is used on-site for deep research, analysis of the excavation area, and other research purposes.

What is Geographic Text Analysis?

If you have seen the geographical texts closely, you know that each text shows us a wealth of information about different locations, the history of these places, and how they were formed. The Geographic Information System, however, focuses on the quantitative data currently and thus ignores the textual sources. It has become more important, now than ever, for the researchers to implement the right GIS tools to ensure that it works with the qualitative and textual data.

That’s because most of the materials that are available for the scholars are in the textual format. This varies from digital archives to digital sources. These textual sources contain millions of words that contain a considerable amount of useful data. It is, therefore, important for geographers to research and introduce new techniques that can help researchers understand the textual data without any difficulty.

The Connection Between GTA and GIS

Geographical Text Analysis (GTA) and Geographic Information System (GIS) are two important areas that are interrelated but they hardly communicate. If these systems become compatible, they have plenty to offer to each other. GTA involves multiple steps, each should be followed closely and thoroughly so you can obtain information about the geographies and learn more about the archaeological surveys.

First thing first, each text contains the name of the place, which is the first thing you are supposed to identify. This step makes it easier for the researcher to map the corpus without any difficulty. Once the place is identified and the corpus is mapped, it gets easier for the researchers and scientists to start more crucial and comprehensive research that helps them understand what exactly the corpus is talking about where it is pointing to.

This is done by combining the geographical texts with the GIS-based tools. The research includes a wide variety of examples, ranging from the small corpus that shares limited information about geography to the large corpus that helps us learn more about the geographical locations of the 17th century and before that.

That’s how the GIS tools are used for Geographical Text Analysis. They help make the GTA comprehensible and efficient. The technology can help researchers understand the textual data for a better understanding of the locations.
