The GENESIS Services Portal provides the user interface to discover and activate the GENESIS Web Services. This portal implementation is based on the Liferay Open Source Portal taking advantage of all built-in features of this leading portal solution:

• standard portlets (page fragments) JSR-286-based allowing an administrator to configure the portal pages with predefined page components (such as content management portlets, news) through the portal user interface
• allowing to easily update the portal look & feel using Liferay themes
• user management

The GENESIS Services Portal extends Liferay by providing additional portlets based on latest web user interface frameworks: JSF and AJAX engine. It also integrates the Liferay user management with the GENESIS User Management.

Here is an example of processing activation and service results on the map or as graphics

 

Achievements

Different GENESIS portlets are now available to:

• query remote catalogues to discover services and different types of meta data (GIS dataset, EO dataset, EO dataset series, In-situ data)
• activate orchestration of remote processing and display processing results on the geodata visualization Portlets
• support users taking decisions based on current and past situations , along with data acquired from In situ data SOS Services
• provide a view on the overall GENESIS system status (different connected servers and services status), providing metrics and graphics for the performance on different system elements. Alerting over availability or performances on Hardware or Software Services

The GENESIS Geodata Visualisation Portlet system provides a powerful and flexible WebGIS Client that can be instantiated in various forms and with varying functionality inside any JSR286 compliant portal or used standalone. Each GENESIS Service Client can hence be shown with a customized geographic interface. GENESIS service providers can make use of a configuration portlet to entirely configure their cartographic interface to their liking. The map configurations are fully managed through an internal geographically enabled Content Management System with versioning, access right control and gathering of usage statistics.
The Geodata Visualisation Portlets allow:

• Connecting to OGC Web Map, Feature, Coverage and Sensor Observation Services
• Import and visualize vector and raster data in various formats with on the fly-reprojection
• Export maps and data in various formats
• Configurable layer management: functionality with grouping, legends, transparency control
• Range of typical map navigation tools including zooming and panning tools, overview map and zoom to gazetteer
• Advanced querying functionality for feature data with customisable query forms and dynamic result tables for each specific feature data set.
• Possible to display graphs on the basis of feature datasets (Bar, Pie charts) and Observations (time series plots)
• Play animations of time-varying geographic data (WMS & features)
