Feature Attribute Table

A Feature Attribute Table (FAT) is a database table used in Geographic Information Systems (GIS) to store descriptive information about geographic features within a feature class. Each row represents an individual spatial feature, while each column contains an attribute such as a feature ID, name, type, classification, measurement, code, or other descriptive data. The table links spatial objects to their non-spatial information, enabling users to organize, search, edit, and analyze geographic data efficiently. Feature Attribute Tables play a vital role in GIS by supporting data management, spatial queries, thematic mapping, and decision-making. They help maintain data consistency, improve data integrity, and simplify updates across large spatial datasets. FATs also enable seamless integration with other GIS layers, databases, and applications, making them an essential component for storing, managing, and analyzing spatial information in fields such as mapping, urban planning, environmental management, transportation, and land administration.
