Based on various experiences in developing Geodata Infrastructures (GDI) for scientific applications, this article proposes the concept of a Scientific GDI that can be used by scientists in environmental and earth sciences to share and disseminate their research results and related analysis methods. Scientific GDI is understood as an approach to tackle the(More)
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).(More)
Enabling the integration of information provided by OGC Web Processing Services into geospatial mass-market applications is promising, as it increases the availability of information for most ordinary users. This information will be most likely based on the latest available data (e.g. collected by sensors) and can thereby support the user in(More)
A three-dimensional solute transport model with biological reactions is presented for simulating the natural attenuation study (NATS) at the Columbus Air Force Base in eastern Mississippi. NATS consisted of the release of a petroleum-based nonaqueous phase liquid (NAPL) and subsequent monitoring of BTEX (benzene, toluene, ethylbenzene, p-xylene),(More)
Progress in the technical provision of spatial operations as loosely-coupled interoperable web services requires a corresponding development of standardisation in their description. Operation discovery, usage and interpretation of results require more information on what a spatial operation does than just their input and output interface specifications.(More)
