PR – The British Geological Survey in Nottingham has begun using the mapClient and securityManager components of con terra’s sdi.suite software. It has already incorporated it in a Natural Environment Research Council (NERC) portal.
The NERC is the United Kingdom’s leading institution conducting fundamental, strategic and applied research in environmental sciences. An initial prototype of the Environmental Data Portal (EDP), which is financed by the NERC, has already been implemented. It enables the visualisation of global, regional, and local data provided by the various institutions represented in the NERC. These institutions include the British Geological Survey (BGS), the British Atmospheric Data Centre (BADC) and the British Antarctic Survey (BAS). The Environmental Data Portal contains search functions to allows users to conduct research involving a wide variety of data contexts. The search results are displayed in the form of map services (OGC WMS) in a browser-based map client based on the sdi.suite’s mapClient.
The BGS, the world’s oldest national geological surveying institution, is responsible for the implementation of mapClient within the portal.
In addition to the extensive analytical functions available as standard in mapClient, such as superimposition, transparent switching and feature queries, con terra GmbH was assigned by the BGS to add a number of special functions.
One requirement was that it should support dynamic initialisation, to enable the presentation of particular WMS services which have already been searched in the existing search portal in elaborated contexts. Due to the special nature of the data underlying the map services, it was also necessary to implement functions which allow the user to select time and altitude parameters at runtime. These parameters are read from the WMS Capabilities (1.1 and 1.3) and displayed via a context menu and relevant dialogue fields. By selecting a particular time point, different temperature distributions can, for instance, be displayed on the basis of one and the same service layer. The same applies when querying different altitude tiers of a layer. Other dimensions can be added as required.
The main criteria on which the BGS based its decision to implement con terra’s sdi.suite technology was its high level of flexibility, its scope for extensions, and the comprehensive compliance of mapClient and securityManager with relevant OGC standards.
