What does a Table in GIS represent?

1. A graphical representation of GIS data

2. A collection of rows and columns representing entities

3. A layer containing only spatial data

4. A database structure without relationships

The correct answer is: A collection of rows and columns representing entities

A table in GIS serves as an essential data structure that organizes information in a format that is both accessible and useful. It is composed of rows and columns, where each row represents a unique entity or record—such as a specific location, feature, or observation—while each column corresponds to a property or attribute of these entities. This structured format allows for efficient data handling, storage, and retrieval, making it possible to perform various analyses and queries. The organization of data in tables helps facilitate the integration with spatial data, where tables often complement their spatial layout by providing attribute information crucial for mapping and analysis. For instance, a table containing attributes like population, land use, or temperature can be linked to geographic features such as polygons representing land parcels or points marking specific locations. In contrast, other answer choices do not accurately encapsulate the role of a table in GIS. While a graphical representation might be part of data visualization efforts, it does not convey the structured nature of the data itself. A layer containing only spatial data minimizes the significance of tabular information, which is critical for analyzing geospatial variables. Lastly, although databases can contain structures without relationships, in GIS, the relational aspect is often integral to linking spatial features with their corresponding attributes, thus undersc
