What does a layer mean in a GeoServer?

In GeoServer, the term “layer” refers to a raster or vector dataset that represents a collection of geographic features. Vector layers are analogous to “featureTypes” and raster layers are analogous to “coverages”. All layers have a source of data, known as a Store. The layer is associated with the Workspace in which the Store is defined.

Why do I need GEOs in my GeoServer?

GEOS (Geometry Engine, Open Source) is an optional component of a PostGIS installation. It is recommended that GEOS be installed with any PostGIS instance used by GeoServer, as this allows GeoServer to make use of its functionality when doing spatial operations.

What happens when GEOS is not available in PostGIS?

When GEOS is not available, these operations are performed internally which can result in degraded performance. It is strongly recommended to create a spatial index on tables with a spatial component (i.e. containing a geometry column).
