Browsing ERDAS APOLLO Catalog

On the Browse ERDAS APOLLO Catalog panel, you can browse for all of the data that you are able to access through the Web Client.

In the Browse ERDAS APOLLO Catalog tree, the following elements may be listed depending on conditions that exist in the catalog:

• Services

The Services node shows all of the service providers that you can access through the Web client. These service providers are categorized by the type of protocol used.

• Vectors (WFS) - Web feature service providers. The name of the top-level node for each WFS is set to the title property of the WFS. As the WFS specification provided by the OGC does not support nesting of feature types, child nodes corresponding to layers and are organized in a flat format.
• Maps (WMS) - Web map service providers. This node includes all WMS providers that have been added as well as the base map that is being used in the maps panel. The name of the top-level node for each WMS is set to the title property of the WMS (which is shown in the GetCapabilities document for the WMS). Child nodes correspond to layers and are organized in a hierarchical format, in accordance with OGC specifications for WMS.
• Coverages (WCS) – Web coverage service providers. The name of the top-level node for each WCS is set to the title property of the WCS (which is shown in the GetCapabilities document for the WCS).

• Coverage Catalog - Contents of the ERDAS APOLLO Server catalog that is associated with this Web client.

All of the datasets and aggregates in the catalog are shown as nodes under the ROOT aggregate for the catalog. You can open an aggregate node to see the child aggregates, if there are any. If you click on an aggregate, the Results Panel will display more information about the aggregate and a list of the datasets that it contains.

Detailed information about selected items from the catalog are displayed in the bottom Search Result panel, where you can perform some actions such as adding to the map, viewing metadata, displaying the spatial extent of data on the map, and more (see Working with Search Result Panel).

Only one catalog service can be connected to the Geospatial Portal at once. In order to browse data from another catalog service, you need to remove the actual catalog from registered data sources and then connect a new one.
