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 GIS Consortium (OGC) has proposed a standard for the software architecture of geographic information systems (GIS) in order to enable interoperability among different GIS products. The so-called Abstract Model does not support spatial constraints yet, although most of the later proposals of GIS conceptual data models already do. This paper presents an extension of OGC’s Abstract Model ...

The topological operators defined in the spatial schemata of ISO and OGC for vector geometries can also be applied to raster geometries. This principle ability is investigated here for its semantic implications. From a user’s perspective, topological operators should be applicable to features in any representation and any resolution with a predictable behavior. The conditions and requirements f...

Sensor Web Enablement (SWE) is a consistent standardization e ort of the Open Geospatial Consortium (OGC) to cope with an environment of pervasive sensor networks. The standards suite is web service centric and de nes a number of XML schemas to be used in information exchange. Here we report about an experiment to replace a conventionally programmed web service with one which uses a semantic ne...

Abstract Background There is a paucity of data describing the incidence and causes escalation in level care after oesophagectomy for cancer. This study aimed to address this, including description baseline predisposing variables, contrasting profile among different surgical approaches oesophagectomy. Methods was retrospective analysis prospectively maintained database (‘CODA’) at UK tertiary ce...

Abstract Background Chemoradiotherapy (CRT) is a core component of curative treatment for esophageal cancer locally advanced cancer. Salvage esophagectomy undertaken in patients who experience recurrent or residual post-CRT. This study aims determine the impact delayed surgical intervention following chemoradiotherapy on survival from oesophageal Methods was an international, multi-center, retr...
