The Geospatial Web provides data as well as processing functionality using web interfaces. Typical examples of such processes are models and predictions for spatial data, known as spatial statistics. Such analyses are written by domain experts in scripting languages and rarely exposed as web services. We present a concept of script annotations for automatic deployment in server runtime environm...

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...
