Service GIS SuperMap iServer Java

SuperMap iServer Java is a Java-based powerful, high performance development platform for service GIS. With it, you can publish Web services with GIS capabilities that can compete with professional desktop GIS software.

Architecture of SuperMap iServer

GIS Service Interfaces

You can use SuperMap iServer 6R to publish different types of Web GIS services, including Web Services, and Native Service (such as RML, WCF, and TCP etc). The Web Services here are those services that could be accessed through standard Web protocols, including REST service, SOAP service, OGC W*S service (WMS, WES, WCS, WPS etc), KML service, GeoRSS service, the binary system service. All these services can be published using GIS Service Interfaces. For instance, REST service interface, SOAP service interface. Users can get the GIS service offered by iServer through calling these service interfaces.

The application of Web Service technology into GIS field can solve the problem of heterogeneous spatial information service interoperability, which has been a barrier in GIS application field for years. Web GIS has the characteristics of distributed, interoperable, conveniently aggregating with current GIS resources, as well as excellent scalability. In a word, GIS Web service is a key technology basis to achieve service-oriented GIS.

GIS service interfaces function by calling GIS Service Component.

GIS Service Components

GIS Service Component is achieved by combining services offered by GIS Service Provider, encapsulating larger service component. The GIS Service Component includes Generic and Domain Spatial Service.

The Generic spatial service indicates regular GIS services, for instance, map service, spatial data service, spatial analysis service, network analysis service, etc. While the Domain Spatial Service represents the GIS service used in specific industries. In the latter situation, users may add personal business logic by developing or setting the Generic Spatial Service, which will customize the spatial service in any industry. As a result, the Generic Spatial Service could be applied in many levels in an industry. For instance, in the meteorology field, scientists may get weather forecast service, meteorology warning service etc that are useful in meteorology service on the basis of generic spatial service. With these services, users may easily check the weather of any city that is displayed on the map, and the areas in alert status.

GIS Service Providers

The GIS Service Provider encapsulates and unifies the achievement of GIS functions, including the local components (like SuperMap Objects .NET/Java), remote service (such as RMI service), Web service (such as REST service), or services generated by Service Aggregation.

SuperMap iServer has realized the seamless aggregation and integration of multi-source heterogeneous, through encapsulating and unifying GIS functional entities by GIS service provider.

Other System Components

Besides the GIS functional structure, as an enterprise GIS server, SuperMap iServer has powerful system architecture structure. The components of system subsidiary function contain cluster, cache, management, logging, etc.

With SuperMap iServer Java, you can:

Publish Web services with a complete set of GIS capabilities
Publish standards-compliant services, including OGC WMS, WFS, KML, GeoRSS, and Webservices
Aggregate third-party services, including OGC WMS, WFS, KML, and GeoRSS
Manage your service
Extend your service in multiple levels and multiple tiers
Cluster your GIS servers to ensure high stability and usability
Allow your clients to edit your map data and perform advanced spatial analyses online
Publish services that allow data access through multiple popular browsers, desktops, and mobile PCs
Overlay maps to Google Maps, Virtual Earth, OpenLayers, etc.
