With the advancement of Semantic Technologies, large geospatial data sources have been increasingly published as Linked on Web. The LinkedGeoData project is one most prominent such projects to create a knowledge graph from OpenStreetMap (OSM) with global coverage and interlinking other sources. In this paper, we report ongoing effort exposing relational database in SPARQL endpoint using Virtual...

Environmental decision support systems normally require a data processing workflow based on models to explore alternatives. The typical workflow to handle environmental modelling involves several steps covering data discovery, access, pre-processing, model execution and validation, concluded by result visualization. These time consuming steps are usually setup for a particular scenario and set ...

Recent distributed computing trends advocate the use of Representational State Transfer (REST) to alleviate the inherent complexity of the Web services standards in building service-oriented web applications. In this paper we focus on the particular case of geospatial services interfaced by the OGC Web Processing Service (WPS) specification in order to assess whether WPS-based geospatial servic...

We have developed OWL ontologies for the ISO/OGC model for Observations, and for other standard geographic information schemas (geometry, time, metadata) upon which it depends. Translation from the original UML to OWL follows the ISO 19150-2 rules. The ontologies have been prepared standalone, to respect the ‘upper ontology’ implied by the ISO UML profile and ISO General Feature Model, and thus...

Field spectroscopy has undergone a remarkable growth over the past two decades in terms of use and application to different scientific disciplines. This work presents an important step forward to improve the interoperability for the spectral library interchange in the field spectroscopy scientific community, by establishing an XML-based metadata system using published International Organization...

The CROSS-Fire project aims to develop a grid-based framework as a risk management decision support system for the civil protection authorities, using forest fires as the main case study and FireStation as the standalone CAD application that simulates the fire spread over complex topography. The CROSS-Fire initial tasks focussed on the development of a parallel version of the fire simulator eng...

One of the most widely-implemented service standards provided by the Open Geospatial Consortium (OGC) to the user community is the Web Map Service (WMS). WMS is widely employed globally, but there is limited knowledge of the global distribution, adoption status or the service quality of these online WMS resources. To fill this void, we investigated global WMSs resources and performed distribute...

Spatial data infrastructures (SDI) have been widely accepted to share geospatial data among organizations. Today SDI’s main focus lies on distributed data storage in the form of spatial web services, the retrieval through catalogues, and the visualization in form of web map services. The hypothesis presented in this paper takes SDI’s one step further by providing a method to process geodata, in...

The existing standards dealing with Auto-ID data for supply chain scenarios do not integrate sensor information from the products that are being monitored. In particular, although a number of efforts have been undertaken in the last few years to incorporate sensor data inside the EPCglobal Network, its has proven to be a slow process due to both the complexity of the task and the standardizatio...
