Models as web services using the Open Geospatial Consortium (OGC) Web Processing Service (WPS) standard
Environmental modeling often requires the use of multiple data sources, models, and analysis routines coupled into a workflow to answer a research question. Coupling these computational resources can be accomplished using various tools, each requiring the developer to follow a specific protocol to ensure that components are linkable. Despite these coupling tools, it is not always straight forwa...
متن کاملThe OGC web coverage processing service (WCPS) standard
Imagery is more and more becoming integral part of geo services. More generally, an increasing variety of sensors is generating massive amounts of data whose quantized nature frequently leads to rasterized data structures. Examples include 1-D time series, 2-D imagery, 3-D image time series and x/y/z spatial cubes, and 4-D x/y/z/t spatio-temporal cubes. The massive proliferation of such raster ...
متن کاملHow to Define 3D Geoprocessing Operations for the OGC Web Processing Service (WPS)? Towards a Classification of 3D Operations
In the literature a number of taxonomies are present which categorize the functions of GIS. While such taxonomies used to be more of scientific interest they are now getting more practical relevance due to the adoption of the OGC Web Processing Service (WPS) specification. While this standard currently allows specifying arbitrary geoprocessing functionalities, for ensuring interoperability we a...
متن کاملAsynchronous Geospatial Processing: An Event-Driven Push-Based Architecture for the OGC Web Processing Service
Geospatial processing tasks like solar potential analyses or floodplain investigations within flood scenarios are often complex and deal with large amounts of data. If such analysis operations are performed in distributed web-based systems, technical capabilities are mostly not sufficient. Major shortcomings comprise the potentially long execution times and the vast amount of messaging overhead...
متن کاملOGC Web Processing Service Interface for Web Service Orchestration Aggregating Geo-processing Services in a Bomb Threat Scenario
The aggregation of web services in order to achieve a common goal is a basic concept in Service Oriented Architectures (SOA). This paper demonstrates OGC Web Services (OWS) aggregation based on a simulated bomb threat scenario which is a possible disaster management example. Web services are aggregated based on the OGC Web Processing Service (WPS) interface. Here the concept of a “Composite-WPS...
