The WISERD GeoPortal: A tool for the discovery of socio-economic research data in Wales

GeoServerOSGeo
The Wales Institute of Socio-Economic Research, Data and Methods (WISERD) is an interdisciplinary, cross-institutional academic research group based in Wales, UK. One of the roles of the WISERD GIS/Data Integration Team is to develop a spatial framework that enhances a researcher's ability to discover survey (government and academic), public, administrative and 'grey' socio-economic data (both quantitative and qualitative) relating to Wales, with the aim of encouraging collaborative research and re-use of existing data. This paper describes the development of an online GeoPortal designed to meet this objective. Using free and open-source software (FOSS) components and services, a range of software has been developed to capture standards compliant metadata for a variety of data sources. This software has enabled the WISERD Data Integration Team to build a rich meta-database of government surveys (down to question level), geo-referenced semantically-tagged qualitative data (generated from primary WISERD research), grey data (e.g. Transcripts, journal publications, books, Ph.D. theses) and geo-referenced administrative data (e.g. education data from schools). Using a FOSS stack (PostgreSQL, PostGIS, GeoServer, GeoWebcache, OpenLayers/GeoExt/Extjs) a GeoPortal has been developed that enables end users to query the meta-database using a number of tools.
 
Tools for interrogating the data include simple keyword searches, more complex text queries, point-and-click tools and spatial analysis tools. These features enable the end user to query the meta-database using traditional text-based methods or by using a dynamic cartographic interface to search for data spatially. Moreover, using RDF and SPARQL, external data sources may also be linked and queried (e.g. Data.gov.uk, Ordnance Survey) to return any datasets pertaining to the search parameters. The results of the search are returned in traditional list format but with the ability to view more detailed metadata relating to the survey (e.g. response rates, number of questions, frequency, spatial coverage, collection techniques etc.). Results can be presented for discrete spatial units or as points prior to further spatial analysis and data pooling. The full paper describes the challenges faced during the development of the WISERD GeoPortal and the plans for the application in terms of usability testing, the incorporation of new data sources and the development of more advanced search and analysis tools. The paper provides an objective assessment of open source technologies for the discovery, reuse and analysis of disparate data and resources for the social sciences. We conclude by making a series of recommendations for those charged with developing geoportals using such tools based on user experiences to date.

Advancing global marine biogeography research with open source GIS software and cloud computing

in FOSS4G, FOSS4G2011, Government, Video, OSGeo
OSGeo
Across many scientific domains, the ability to aggregate disparate datasets enables more meaningful global analyses, with parallel computation and GIS challenges.  Within marine biology, the 10-year Census of Marine Life served as the catalyst for such a global data aggregation effort.  Under the Census framework, the Ocean Biogeographic Information System (OBIS, www.iobis.org) was established to coordinate an unprecedented aggregation of global marine biogeography data.  The OBIS data system now contains 30 million observations, representing 120,000 marine species, freely and openly accessible through a public database and online geospatial portal.  OBIS data have been used for analysis and conservation efforts worldwide.
 
The challenges of storing, querying, disseminating, and mapping a global data collection of this complexity and magnitude are significant.  After several years of declining performance and expanding requirements, a redevelopment of the OBIS data system was undertaken.  Following an open source philosophy, the OBIS technology stack was rebuilt using PostgreSQL+PostGIS, GeoServer and OpenLayers.  This approach has markedly improved the performance and online user experience while maintaining a standards-compliant and interoperable framework. 
 
Previous OBIS system development focused on self-contained application stacks housed at participant research institutions.  Due to the distributed nature of the project and increasing storage needs, a more flexible hardware plan was implemented during this re-engineering effort.  The Amazon EC2 cloud provided the deployment flexibility and scalability to allow the system to expand within a commonly accessible environment.  Cloud technology helped to centralize OBIS development and will support future instantiation tools, scripts, and APIs for system researchers.
 
Techniques to address the scale of the data system and diverse demands on data exploration, as well as challenges and lessons learned from the OBIS portal redevelopment and Amazon cloud implementation will be presented.  Improved cooperation on FOSS4G approaches to eco-informatics challenges will also be discussed.

INTELIGEO - Geographic Intelligence System

in FOSS4G, FOSS4G2011, GIS, Government, Video, OSGeo
OSGeo

In the last five years the world has seen an ever-increasing use of geospatial data in a wide array of human activities. Individuals and organizations have come to rely on services such as Google Maps for many daily tasks. In Law Enforcement, geospatial data services, usually accessed through web browsers, may help to improve the efficiency of routine tasks like route planning, address location and allow for more advanced applications, such as georeferenced information sharing and crime pattern identification.

As of 2010, the Brazilian Federal Police – BFP doesn't have an institutionalized geospatial system to store, access and analyze crime related information, something that would assist in investigations, field surveys and statistical analysis. To fill this gap, and considering the need to gather and consolidate the spatial data produced by forensic expert's field work and by other agencies, the BFP has devised a system named INTELIGEO.
This system, entered in production on November 2010 running on dedicated servers using the best tools available in the market for geospatial interaction, in a hybrid solution a combination of proprietary and open source software (namely ArcGIS Server and Geoserver).

The functionalities provided by INTELIGEO will allow its users to lookup addresses and other geographical information, plan police operations on urban and remote locations, access satellite imagery for crime scenes and interact with different data formats, especially vector and raster formats. The system will go beyond, enabling the construction of thematic maps of the evolution of crimes, drug trafficking flows, the advance of deforestation in Amazon's rain forest and any other geospatially referenceable crime.

Despite already available for users, INTELIGEO is still in an embryonic state, requiring financial and human resources support to advance its development and become the standard WEBGIS for the Brazilian Federal Police.
