Demonstration OSPER/SwissExperiment | | I. Iosifescu et al. 09.05.14 2

SwissExperiment / OSPER § OSPER = Open Support Platform for Environmental Research § Main goal: a sustainable support infrastructure for data acquisition, management and visualization § Enables new advances in science through: § Sharing of resources § Common access point for experimental data § Documentation and safe (but visible) storage of experimental data § Combination of diverse data sources (experimental, geodata, archive data, documents, additional multimedia information, … ) | | I. Iosifescu et al. 09.05.14 3

OSPER Infrastructure Components 1. Data documentation system (SwissEx Semantic Wiki) 2. Sensor data management system (GSN) 3. Service-driven Web GIS platform (powered by GeoVITe) | | I. Iosifescu et al. 09.05.14 4

Handling of Sensor Measurements § First option: use a database or SWE § (Automatic) sensor measurements import into spatially enabled database (PostgreSQL/PostGIS) § Advantage: use of spatially enabled database/WPS means no additional effort to integrate with GIS § Disadvantage: high implementation effort for loading the sensor data into the database (different types of sensors, hardware dependent, etc … ) | | I. Iosifescu et al. 09.05.14 7

Handling of Sensor Measurements § Second option: use GSN § Advantage: facilitates the deployment and programming of sensor networks § Disadvantage: interoperability with GIS had to be additionally implemented (via GML) and maintained | | I. Iosifescu et al. 09.05.14 8

Global Sensor Networks | | I. Iosifescu et al. 09.05.14 9

GeoVITe GIS Platform for Environmental Research | | I. Iosifescu et al. 09.05.14 10

GeoVITe § Geo data V isualization and I nteractive T raining E nvironment § Web-platform for straightforward geodata visualization, selection and download § An official distribution channel for geodata at ETH Zurich for research and educational purposes § User-friendly, easy to use § Fast access to data § Modern | | I. Iosifescu et al. 09.05.14 11

GeoVITe – Simple and Effective | | I. Iosifescu et al. 09.05.14 12

Conclusions § Integrated documentation, management and visualization of sensor data § Flexible infrastructure in respect with changing requirements and APIs § User-friendly visual data mining of existing datasets (without the need for a catalog) § Outlook: § Increase performance and reliability (for wiki, GSN and GeoVITe) § Improve the public GIS platform prototype | | I.
