Spatial Data Infrastructure

TIGERS is extending and developing its fields of activities using Spatial Data Infrastructure (SDI), the state-of-the-art information technology to disseminate geospatial data.

An SDI could be defined as the base collection of technologies, data, human resources, policies, institutional arrangements, and partnerships that enable the availability, exchange of and access to geographically-related information using common practices, protocols, and specifications. SDI consists of a framework that enables users with different mandates and disciplines to operate in a cooperative and cohesive manner to acquire access, retrieve, analyze and disseminate geospatial data and information in an easy and secure way. It particularly helps to improve the efficiency of development, management, use and maintenance of geospatial databases . 


The concept of SDIs resides in “working smarter, not harder” by reusing data, technical capabilities, skills, intellectual effort and capital, through the sharing of human resources, technology and infrastructure. SDIs rely on the development of policies, technologies, data, common standards, standard practices, protocols and specifications such as those of the Open Geospatial Consortium (OGC).

Through its various research projects and collaborations, TIGERS is developing and managing the UNIGE/GRID SDI in order to make geospatial and tabular databases available to members of University of Geneva (scientists, students) as well as the general public .

TIGERS members have a good knowledge and experience in the following areas :

  • Interoperability standards: OGC (WMS, WFS, WCS, WPS, CS-W)
  • Metadata standards: ISO (19115, 19139, 19119), Dublin Core
  • Metadata: Geonetwork, ESRI GeoPortal, GI-cat
  • Databases: PostgresSQL, MySQL, Access, Esri Geodatabase
  • Spatial Engine: PostGIS, ArcSDE
  • Web Mapping: UMN Mapserver, ArcGIS APIs, Open Layers, GeoNode
  • GIS Servers: ArcGIS Server, GeoServer, THREDDS, HydroServer
  • Geoprocessing: PyWPS, 52north WPS, Taverna Workflow Management
  • Crowdsourcing: Ushahidi

The TIGERS SDI aims to support and serve data through the main international/trans-boundary initiatives:

The added value of the UNIGE/GRID-SDI is that it will benefit of distributed computational technology, allowing the user, not only to discover and access data in a standardized and interoperable way but also to analyze and process large amount of high-resolution data
