Attribute Table in QGIS#

🔙Back to Homepage

The attribute table, a core component of Geographic Information Systems (GIS), organizes and presents detailed information about features in a selected layer. Each row in the table represents a feature, while columns store specific attributes. This table facilitates searching, selection, sorting, filtering, and editing of features.
