How to Apply Sensor Web Technologies to Provide INSPIRE-compliant Download Services for Observation Data

July 12, 2018, 10:00 am CEST

The importance of sensors for measuring the environment has notably increased in the past few years. This results in a diversity of available data formats and interfaces. Corresponding standards, such as the OGC Sensor Web Enablement specifications, are necessary to enable simple and interoperable access to measurement data.

The INSPIRE Directive aims to simplify the exchange of geospatial data within Europe. Whereas the exchange of conventional geodata, such as maps and vector data, is well established in the INSPIRE framework, new approaches for sharing observation data have been developed more recently. This is particularly relevant for additional data topics specified in Annex II and III that may cover different types of observation data.

The “INSPIRE Technical Guidelines for Download Services” describe how to set up INSPIRE download services for different types geospatial data. This webinar will introduce two elements of the INSPIRE Technical Guidelines which cover aspects of observation data: the “Guidelines for the use of Observations & Measurements and Sensor Web Enablement-related standards in INSPIRE” and the “Technical Guidance for implementing download services using the OGC Sensor Observation Service and ISO 19143 Filter Encoding”.

Alexander Kotsev (JRC), Sylvain Grellet and Mickael Beaufils (BGRM) and Simon Jirka (52°North) discuss how to publish observation data via the SOS within the context of INSPIRE.

Event-based Dissemination and Processing of Geospatial Information

Pre-conference workshop at the 20th AGILE International Conference on Geographic Information Science, Wageningen, May 9, 2017

About

Event-based architectures are increasingly used in various mainstream IT applications including the financial sector or large scale IoT applications. However, the geospatial domain, especially spatial data infrastructures, often relies on the traditional Web Service pattern (request/response pattern). This full day workshop aims to discuss the potential of event-based architectures in geospatial applications (e.g. disaster management, environmental monitoring, or public security) and to set up a corresponding research agenda. The morning session comprises invited expert talks on event-based technologies and applications. In the afternoon, the challenges for event-processing and event-driven architectures will be identified and discussed in break-out groups. In a final session, the results will be collected and discussed to serve as input for a joint report on the current state of event-based approaches for geospatial information provision and processing.

Objectives

• Gather an overview on event-based approaches for providing and processing geospatial information
• Identify relevant application domains and use cases
• Identify patterns for eventing in spatial data infrastructures and architectures
• Identify and discuss current research topics

We invite you to submit a short presentation on the following topics:

• Handling events in Sensor Web infrastructures
• Event processing of spatio-temporal information
• Publish/Subscribe patterns in Spatial Data Infrastructures
• IoT applications in the geospatial domain
• Applying mainstream IT eventing technologies in Geo-IT applications

Planned agenda

If you are interested in giving a short presentation, please send the title and a brief abstract of about 50 words to Christoph Stasch () or Simon Jirka () by April 30, 2017.
