# Joining Geodata (Spatial and non-spatial joins) <a id="joining-geodata-spatial-and-non-spatial-joins"></a>

__🔙[Back to Homepage](../intro.md)__


In GIS, joins combine data from two tables based on a common field (non-spatial join) or based on location/geometry (spatial join).
Spatial joins link attributes based on geographic relationships (like intersection or proximity), while non-spatial joins rely on matching attribute values (like IDs).
