Geospatial SDI Product Details

Geospatial SDI Ensures Compliance Standards for Web Services

Geospatial SDI is an interoperable and scalable component of spatial data infrastructure for cataloging and delivering enterprise geospatial data over the web. It is designed for data providers that need to manage and serve secure or licensed information using standards- based web services. It offers powerful tools for controlled access to standards-compliant services and data published by those services, as well as tools for monitoring and reporting service performance. The product adheres to Open Geospatial Consortium (OGC®), and International Standards Organization (ISO) standards for web services and metadata compliance.

Geospatial SDI can easily extend solutions based on GeoMedia® WebMap, ERDAS APOLLO, or any other vendor’s OGC-compliant product to ensure that the full set of services required for implementation of custom secure Spatial Data Infrastructure (SDI) are available.

Geospatial SDI is offered within the Platform Suite® of the Power Portfolio®. The Platform Suite enables you to create your own unique application on top of a solid foundation of powerful geospatial functionality. Supported by robust toolkits, detailed instructions, and interactive developer communities, the suite helps you build custom web, mobile, and other smart enterprise solutions.

Secure Access to OGC-Compliant Web Services

In recent years, OGC Web Services have become the standard for the creation and exploitation of SDIs. However, OGC standards do not address secure access to these web services, which precludes their use for publishing protected or licensed data. Filling this functional gap represents a critical factor in determining the success of applying OGC interfaces to the delivery of spatial data infrastructures. For providers that need to manage and serve secure or licensed information using standards-based web services, Hexagon’s Geospatial division offers Geospatial SDI as part of its comprehensive SDI solutions family. The product provides comprehensive web service support for these key secured and monitored OGC-compliant services: WMS, WFS, WCS and WMTS.

Geospatial SDI enables configuring of user access permissions for the service instance, the dataset, feature class (WFS service) or layer (WMS service), and spatial area. In addition, an access permission may be granted to the user for a limited time (time period, weekday, time of day) and an IP address. 

Compatible with Any OGC-Compliant Client 

Notwithstanding secure access control, the objective is to enable ubiquitous communication via OGC standard interfaces. Therefore, at the simplest level, Geospatial SDI enables authentication using an IP address or IP address range. This provides compatibility with any client application that adheres to OGC standards while at the same time ensuring secure access control.

Alternatively, or additionally, Vendor Specific Parameters (VSP) can be added on top of the base web service, with user and password information. This information can also be incorporated, as it often is, in the HTTP heading. Similarly, the IP address can be interpreted and revised by Geospatial SDI. The additional information provided by the VSP query is compatible with most OGC compliant clients, including all products in the GeoMedia® family. 

Easy Answers for Who, What, When and Where

Geospatial SDI extends the services suite offered in GeoMedia® WebMap with the standards-based CSW (Catalogue Service for the Web) service. This type of service is the primary tool for discovery, access, maintenance, and organization of catalogs of geospatial metadata that describe data and related resources available within enterprise or public Spatial Data Infrastructure (SDI).

Compatible with Any Façade Architecture

Geospatial SDI functions as a façade, providing a proxy over existing WMS, WMTS, WFS and WCS services. This architecture is also known as proxy OGC Web Service (proxy OWS), an intermediate component that allows and manages communication with OGC web services. The service user (client) communicates directly with the façade, which filters the request based on user rights (and/or other criteria) before passing it to the appropriate data services. The results can be served directly to the client or manipulated before return. This façade architecture also supports the use of web services from other providers.

Quality of Administration, Configuration, and Service Control

A web-based administrative console provides the means for creating and configuring all aspects of server-side engines, web services and web applications in one place. Web service instances for any type of service can be created, configured, and removed. Geospatial SDI also enables management and monitoring of published services. Advanced features include user-event logging and measurement of service performance.

Ease of Integration

Geospatial SDI uses an open interface and ensures easy integration with other Hexagon Geospatial solutions as well as third-party external services. Modification of standard web services is not required, thanks to the use of vendor-specific OGC parameters and/or IP addresses.

Integration with the Wider IT System Environment

Often, data providers own administrative databases, such as those used for e-commerce transactions. Geospatial SDI includes adapters that allow it to connect to existing administrative databases, avoiding the need to create and maintain redundant information. 

Connected Solution

Geospatial SDI extends compliance for any vendor’s OGC-compliant product, to assure the full set of services required for implementation of custom secure SDI.
