Nowadays, producers of geospatial data in either raster or vector formats are able to make them available on the World Wide Web by deploying web services that enable users to access and query on those contents even without specific software for geoprocessing. Several providers around the world have deployed instances of WMS (Web Map Service), WFS (Web Feature Service) and WCS (Web Coverage Serv...

The term Digital Earth was coined in 1998 by Al Gore proclaiming a three-dimensional multiresolution representation of the Earth’s surface holding georeferenced data of any kind (ISDE, 1998). Part of this vision is the ubiquity of observation systems, enabling a digital representation of features such as environmental phenomena with a high spatial and temporal resolution. World wide a vast amou...

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...
