1.1. deegree: Setting up interoperable INSPIRE Download Services in 3 hours

Abstract:

"The INSPIRE directive aims to create a European Union (EU) spatial data infrastructure. After Discovery Services (metadata catalogues) and View Services (map servers), the next big thing on the INSPIRE roadmap are Download Services. Download Services provide access to the geospatial base data of the member states. Take this workshop to learn the requirements and the implementation of compliant INSPIRE Download Services using FOSS packages. What are the differences between "Predefined Dataset and "Direct Access" Download Services? What are "non-interoperable" and "interoperable" Download Services? What are the Data Themes (Annex I-III)? When is harmonization of base data required and how to approach it in practice?

This workshop will focus on a hands-on implementation of a full monty Download Service (interoperable, direct access) using deegree webservices. We will explore the different INSPIRE requirements (e.g. standards, metadata coupling, quality-of-service) and discuss options for efficient storage of rich INSPIRE features. We will perform an example harmonization based on deegree's relational mapping language and look at other FOSS options for transforming existing base data into harmonized, valid INSPIRE datasets."

2.1. deegree: Turn-key solution for interoperable INSPIRE Download Services

Abstract:

"The INSPIRE directive aims to create a European Union (EU) spatial data infrastructure. After Discovery Services (metadata catalogues) and View Services (map servers), the next big thing on the INSPIRE roadmap are Download Services. Download Services provide access to the geospatial base data of the member states. This presentation outlines the requirements and the successful implementation of compliant INSPIRE Download Services using FOSS. What are the differences between "Predefined Dataset and "Direct Access" Download Services? What are "non-interoperable" and "interoperable" Download Services? What are the Data Themes (Annex I-III)? When is harmonization of base data required and how to approach it in practice?

After providing an overview on the formal requirements, the presentation will turn to the special features of the deegree WFS. This thorough implementation of the OGC WFS 2.0 standard has a special focus on smooth handling of rich data models, such as INSPIRE Data Themes. This includes a powerful relational mapping language and an alternative storage approach which guarantees efficient reconstruction of rich features from spatial SQL databases, such as PostGIS."

2.2. Tiles and more - deegree freshly implements WMTS

Abstract:

"In 2013, a new service type joined the deegree family - the deegree Web Map Tile Service. This deegree service implements the OGC WMTS 1.0.0 specification and is going to be the OGC reference implementation for this specification. Both, the OGC WMTS test suite and deegree's candidate reference implementation have been developed within the OGC OWS-9 initiative.

The intention for implementing WMTS was that deegree had no clear strategy to handle big raster data. As a result, one of the advantages of deegree WMTS is the performant handling of big raster data - such as aerial images - and providing it through a standard-compliant interface. Additionally there is advanced support for using other web services based on OGC WMS and WMTS such as GeoServer, GeoWebCache and Mapserver as datasource for deegree's tiling API, which is the underlying data access layer of the WMTS. As a key feature deegree is capable of proxying FeatureInfo output from those remote services.

The presentation will give an overview about deegree WMTS and all its capabilities, especially regarding the interfaces with other OSGeo components."
