In the domain of housing market analyses decision makers typically are supported by Geographic Information Systems (GIS). The new Web Processing Service (WPS) standard of the Open Geospatial Consortium (OGC) offers nowadays the possibility to realize GIS analysis functionalities also on the Internet via a standardized interface. In this article we present how we applied the WPS specification fo...

The Soil and Water Assessment Tool (SWAT) is a widely used hydrological model that produces several useful outputs (e.g. evapotranspiration, soil moisture, aquifer recharge, river discharge) as text files. Currently, visualizing and publishing SWAT outputs as geospatial data requires a lot of time and repetitive processing steps. Moreover, data used and produced are often not interoperable and ...

The Open Geospatial Consortium Web Processing Service proposed specification is intended as a solution for developing web-based geoprocessing plugins, and for easily sharing algorithms and geoprocessing functionality. This paper seeks to evaluate the WPS proposal with respect to feasibility and potential utility, and to identify areas for improvement. Challenges with the WPS proposal are discus...

Taiwan is located at the collision boundary of the Philippine sea plate and the Eurasian plate. The mountain terrain is precipitous and the region, on the whole, is characterized by fragile rocks and frequent seismic activity. In addition, the concentrated torrential rainfall brought by typhoons cause extensive disasters, debris flow, the most serious disaster caused by torrential rainfall, lea...

A service is presented that assesses the quality of measurements of daily global irradiation or means of global irradiance acquired by a ground station. Measurements are checked against models resulting in a measure of plausibility. This on-line service obeys the WPS (Web Processing Service) standard of the Open Geospatial Consortium. It is free of use and can be integrated into routine operati...

While the satellite data and meteorological measurement are more easily available, there is a lack of comprehensive framework that provides an estimated air temperature map with ease of use to the end-users. This study focus on the developing of a comprehensive web based framework for estimating air temperature map from MODIS LST evaluated relationship with in-situ data collected over a distrib...

Bringing the full set of GIS (Geographical Information System) functionality into a SOA (Service-oriented Architecture) based environment is one of the substantial changes in the GIS domain. Standardized data access and coordinate transformation and visualization functionality are already available and commonly used in Spatial Data Infrastructures (SDI). Nevertheless, one problem still remains:...

The standards developed by the Open Geospatial Consortium (OGC) provide a broad foundation for web-based geographical applications. As one of these the OGC Sensor Web Enablement (SWE), which comprises standards for the consumerand provider-oriented sensor viewpoint, allows data requests of real-time sensor measurements and observations, abstracting from the inherent sensor particularities. The ...

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...
