What is layer group GeoServer?
A layer group is a container in which layers and other layer groups can be organized in a hierarchical structure. A layer group can be referred to by a single name in WMS requests. This allows simpler requests, as one layer can be specified instead of multiple individual layers.
What is the difference between WMS and WCS?
A warehouse control system (WCS) directs “real-time” activities within warehouses and distribution centers. On the other hand, a warehouse management system (WMS) is more focused on broader activities, people, and processes, such as shipments and orders.
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.
When to remove the root layer in GeoServer?
Capabilities documents in GeoServer always have a top level (root) Layer element that works as a container of all the available layers and groups. When a layer group is the only top level element in the Capabilities document, it is possible to remove this root Layer and return a hierarchy where the layer group is the root instead.
How does GeoServer automatically reproject all layers to the projection group?
GeoServer automatically reprojects all layers to the projection of the layer group. The new Enabled checkbox, if disabled, will cause the layer group to just show up at configuration time (and in REST config), while the new Advertised checkbox, if unchecked, will make it to not be available in GetCapabilities request and in the layer preview.
How does the drawing rule work in GeoServer?
The drawing rule determines the appearance of a layer depending on attribute properties. GeoServer displays the symbology of a layer with the help of SLD (Styled Layer Descriptor, a XML based dialect), which can be created or changed in the styles dialog.
