The table offers a rich set of geospatial data, with columns providing geographic information in different formats like geojson and geotext. This data, represented using the WGS 84 coordinate reference system, can be used for detailed geospatial analysis. The geospatial data includes the type of geometric figure (like multipolygon), the centroid (geographical center) of the area, and the x and y coordinates of the center.

A unique aspect of this table is its history tracking. It includes columns for the start and end dates, indicating when the data for a particular row was extracted and when a new version was extracted, respectively. Combined with the row number, these columns allow for unique identification of each row in the table, providing a detailed version history of the base table rows.

This table can be used in a variety of data analytics applications. For example, it can be used in geographical analysis to study changes in the areas over time, or in environmental studies to analyze the impact of climate change on different regions. It can also serve as a rich source for language studies, given the multilingual nature of the data.
