GeoWebCache  Tile Oriented Geospatial Cache  Java Enterprise  Maps Acceleration ( 10x to 100x ) GeoWebCache  Standards compliant  OGC WMS 1.1.1, WMTS 1.0  TMS  WMS-C  Google Earth/Maps support  Stand-Alone or Integrated in Persistent raster/KML GeoServer tile cache

MapStore  Create, Manage, Share Stunning Maps easily  Mashing-up various sources of data  Inject markers and tracks with custom HTML pop-up  Embed in existing sites and portal  Use as complete geoportal solution

GeoNetwork • Metadata ISO19115:2003, ISO19119:2005, ISO19110:2005, – COMMON ISO19139:2007 LANGUAGES FGDC, Dublin Core – EXCHANGE • Export/Import FORMATS RSS & GeoRSS newsfeeds – CATALOGUES/ XML + XSL – WEB SERVICES • Catalogue interfaces – OGC CSW 2.0.2 ISO Profile – OAI-PMH – Z39.50 Geo-OpenSearch – GeoRSS – – WebDAV • Web Mapping Client – OGC standards for WMS, WMC • Web Map Server (through GeoServer) – WMS, WFS, WFS-t, WCS, KML

GeoBatch  Real-time produced data Remote Sensing, In situ, Models, etc..   Recognizable, isolate data streams  Flow Incoming series of geospatial data  Specific format  Defined rules for preprocessing  Defined rules for ingestion and/or exploitation  Automatic Ingestion and preprocessing  No manual intervention   Example, flow of EO raster GeoWebCache Producer Tile Pyramid Publish GeoServer

INSPIRE – Who does What  Discovery service  GeoNetwork  View, Download, InvokeSD, Transformation Service  GeoServer

INSPIRE Discovery Services GeoNetwork  GeoNetwork implements CSW 2.0.2 ISO Profile  INPIRE extended constraints in metadata should be explicitly enabled in GeoNetwork  Complies with almost all main requirements in Metadata Implementation and Discovery Services  Main compliancy issues in:  Handling federated catalogues  in Discovery Service Metadata and Link Discovery Service operations  Federated metadata retrieving  no CSW, only Z39.50  Publishing in pull mode  matching CSW Harvest operation in GN is not stable yet

INSPIRE View Services GeoServer  Historically well supported WMS 1.1.1  GeoServer Stable 2.1.x Supports WMS 1.3  Ordnance Survey (UK) funded the work  INSPIRE compliancy still partial  Harmonized Names (available since 2.2.0 beta)  SOAP Support missing (recommended, not mandatory)  Scenario 2 not supported  Partial support for multilingualism  INSPIRE Community Extension  Separate plugin  Plugs-in additional fields for Multilingualism and Service Metadata

INSPIRE View Services GeoServer  Language support:  Single language declaration support  Limitations  No multilingual metadata on layers  Missing localized support for exceptions  Missing localization support for contents (e.g., GetFeatureInfo, GetMap labels)  Robust support for Mandatory CRS (ETRS89)  Support for Mandatory Encoding Formats (PNG, GIF)  Support for SLD 1.0 solid and mature  Many Additional Vendor Options

INSPIRE View Services GeoServer  Support for SE 1.1 present  extra operations available in SE 1.1 and not in SLD 1.0 are not supported  Some of the above are available as SLD 1.0 vendor extensions (same functionality, different syntax)

INSPIRE View Services GeoWebCache  Full support for WMTS 1.0 (tiled view services)  Harmonized names possible  INSPIRECRS84QUAD tile matrix set not built-in, but manually configurable  Missing INSPIRE extensions:  WMTS Capabilities document does not contain the required INSPIRE extensions (WMS-C do though)  No layer metadata links  Internationalization support missing  No SOAP support

INSPIRE Download Services GeoServer  GeoServer 2.2.0 beta first release to support WFS 2.0 and GML 3.2.1  IGN France Funding  SOAP supported  Missing some functionalities  Standard Capabilites Extension missing  Local and Remote Resolve  GetPropertyValue Interactions with AppSchema/Complex Features  Basic Workflow for Complex features  Store original datasets in ad hoc schema database  Generating Object-Relational mappings  On-the-fly output transformations

INSPIRE Coordinate Transformation Services - GeoServer  GeoServer provides coordinate transformation tools with the gs:Reproject WPS process  Requires some changes to become compliant  Name change  List supported SRS  Use different mime types for GML  Add “test transformation” mode (does not actually transform, checks only if possible)

INSPIRE InvokeSD Services GeoServer  GeoServer Support OGC WPS 1.0.0  Interaction with external WFS and WCS  Automatic Ingestion of produced data  Basic process chaining is supported  Interaction with BPEL/BPMN engine to be tested

LaMMa - MetOc

Acque Wiz EU Project  Crowdsourcing of data losses reports and data quality  Participative approach to water resourcing and planning

Cultura Italia - MuseiD Portal  Integrate with OpenCMS & SOLR  Inject custom markers and tracks with custom HTML pop-up  Mobile Enabled Version  Link-back to managed resources  Example here  No INSPIRE!

Open Data  Tremendous push for business and innovation  Bottom-up process  Current Infrastructures shortcomings  Focus on data rather than on services  Mostly unidirectional  Split between geospatial and non geospatial  Interoperability between Hubs is an open point  There’s room for improvement

INSPIRE  Top-down process  Works by imposition  Complexity, Complexity, Complexity  We really needed more docs to read!  Adapting to INSPIRE is expensive  Existing products  Existing infrastructure  Existing data repositories  Real world moves faster than standardization bodies  Open Data provides momentum, let’s use it!

Conclusions  We work for people  People ask for more data & services not more rules  Complexity generate confusion  Confusion generate failures  Innovation  development of new values  solutions that meet new requirements  inarticulate needs  old market needs in new ways  Open Data initiatives are fostering innovation  INSPIRE does generate business, but innovation?
