What is primarily stored in a Table within a GIS?

1. Spatial relationships between layers

2. Geographic metadata only

3. Tabular data representing entities or occurrences

4. 3D objects with elevation data

The correct answer is: Tabular data representing entities or occurrences

In a Geographic Information System (GIS), a table primarily stores tabular data that represents entities or occurrences. This data typically consists of rows and columns, where each row corresponds to a specific object or instance, and each column represents a different attribute or characteristic of that object. For example, in a table representing land parcels, each row might include information such as parcel ID, owner name, size, and assessed value. This organization allows for efficient data management and querying, enabling users to analyze and relate different attributes associated with geographic features. The ability to store and manipulate this tabular data is crucial for effective data analysis and visualization in GIS applications. On the other hand, spatial relationships between layers, geographic metadata, and 3D objects with elevation data represent different aspects of GIS data. Spatial relationships pertain to how different geographic features interact and connect, while geographic metadata provides descriptive information about the data's source, quality, and lineage. Meanwhile, 3D objects with elevation data are typically stored in specialized formats or data structures designed to handle three-dimensional representations, which do not fall under the traditional tabular representation found in standard tables within a GIS.
