Managing Data Sources

This section is valid for all product flavors.

Geospatial Portal lets you add new data sources of different types and then work with spatial data served by these data sources (services).

For connecting to services, Geospatial Portal offers a set of connectors that lets you consume data and functionalities delivered by the service. Your administrator can predefine a list of services that you can register in Geospatial Portal, but you can also connect other known services. Connecting to the services is completely asynchronous, meaning that you never need to wait for a response from all requested services. In addition, you can stop the call and see only the data that was provided by other services. This approach increases performance and makes the application more reliable – Geospatial Portal never hangs while waiting for an unresponsive service.

Geospatial Portal offers connectors to the following services:

Service Name	Description
WMS (Web Map Service)	For consuming map data delivered by WMS services and presenting it in a map window.
WMTS (Web Map Tile Service)	For consuming map data delivered by WMTS services (raster tiles) and presenting it in a map window. Alternative host names for WMTS service are supported.
WFS (Web Feature Service) WFS-T (WFS Transactional)	For consuming vector data/queries delivered by WFS services and presenting the result in a map window or data window.
WFS-G (Web Feature Service - Gazetteer)	For consuming vector data (gazetteer data) delivered by WFS-G services and presenting it in a map window (as pins) or on a list of found objects.
CSW (Catalog Service)	Provides an interface to discover, browse, and query metadata about data, services, and other potential resources.
WCTS/WPS–CT (Web Coordinate Transformation System)	Performs transformation of GML data from one coordinate system to another.
Google Maps	For consuming map data delivered by the Google Maps service.
Microsoft Bing	For consuming raster map data delivered by the Microsoft Bing service.
OpenLS	For consuming data delivered by OpenLS (Location) services and presenting it in a map window (as pins) or on a list of found objects.
LUWS	For consuming data delivered by LUWS services and presenting it in a map window.
GeoRSS	For consuming data delivered by GeoRSS services and presenting it in a map window.
WebMap Publisher	For consuming map data and vector data, queries, and analysis delivered by a service using the WMPS (WebMap Publisher Service).
Personal (Personal Storage Service - PSS)	For utilizing map and vector data delivered by a user-defined service.
Print Service	For using external print services.
ERDAS APOLLO Essentials	For consuming raster data delivered by ERDAS IWS (Image Web Service) service.
ERDAS APOLLO	For consuming raster, vector data, and services from the ERDAS APOLLO Catalog.
3D Map Tiles	For consuming myVR 3D Map Tiles generated by mTransformer utility. myVR 3D Map Tiles may have embedded 3D objects.
3D Objects	For consuming myVR 3D Objects generated by the mTransformer utility.
Open Street Map	For consuming map data delivered by the Open Street Map service.

The list of available connectors for data sources may vary and may be limited according to the purchased license.

The WebMapPublisher service can contain several applications, so it is necessary to set an application from which maps and data will be consumed. To select an application available for the GWMPS service, use the Application drop-down list in the Data Source dialog box.
To be able to consume ERDAS IWS raster data in Geospatial Portal, the ERDAS ECWP plug-in must be installed on the client machine. This plug-in adds high-performance streaming of both ECW and JP2 geospatial aerial and satellite imagery over the internet. The ECW Protocol (ECWP) and the JPEG 2000 Interactive Protocol (JPIP) from ERDAS APOLLO Essentials Image Web Server are used to work with data in ECWP and JP2 formats. The Microsoft Internet Explorer, Mozilla Firefox, and Google Chrome browsers are supported. To download the plug-in, use the link provided on the Geospatial Portal Welcome Page or contact your Geospatial Portal administrator.
Optionally for the WMTS service, you can provide alternate hostnames for performance reasons in case the given WMTS service supports alternate server names within the WMTS GetCapabilities document. When a list of URLs is registered, Geospatial Portal rotates through the list when requesting GetTiles, which significantly improves the performance.
In order to register the WMTS service with an alternate domain names, open the New Data Source dialog box for WMTS connector; then in the URL field, provide the URL to the service, and select the Use Alternative host names check box. In the Alternative host names field, provide alternate domain names separated by semicolons.
