• Lack of European base cartography,

• Necessity of making interoperable the datasets provided by

different data providers,

• Introduction of INSPIRE directive, as a legislative framework

for all European Member States,

• Fragmentation of available datasets and data sources (time

and scale),

• Duplication in gathering information (time-costs-results),

• Difficulty in the harmonisation at different spatial scales (also

inside the same data source),

Analysed issues

• To share base cartography in order for it to be accessible

(INSPIRE compliance) and interoperable:

cross- border

cross- scale

cross- language

for aggregation purposes and operationally validate the INSPIRE

Implementation Rules,,

• To analyze lack of information and dataset level,

• To share data, without building a central database, but through

services and standards, and create the GIS4EU server for publish

the aggregated data.

Project phases

Provision of interoperable datasets to open GI to EU communitiesJanuary 2008

The project is divided in three major phases

• Conceptual

• Implementation

• Dissemination and guide line

7

Thematic Working Groups

Rules for the composition of TWGs:

• One for each theme,

• TWGs define for the corresponding theme:

Common data model (definition),

Aggregation rules (relation)

• Strict involvement in the provided themes,

• Each data provider is included in at least 2 TWG,

• Different composition of TWG for definition and

relation,

• Composed by DP (NDP, RDP, LDP) + RES + TECH.

Data Sources

Provision of interoperable datasets to open GI to EU communitiesJanuary 2008

We have collected datasets in:• Different model schema (for ex. IntesaGIS, Eurogeographics )• languages of Portugal, Hungary, Slovenia, Italy and Catalonia

We use 51 core datasets some datasets are multi-purpose, in particular:• 23 datasets applied on Transport Networks• 22 datasets applied on Hydrography• 28 datasets applied on Administrative Unit• 15 datasets applied on Elevation

INSPIRE Testing

Provision of interoperable datasets to open GI to EU communitiesJanuary 2008

INSPIRE Consolidation Team as lunching the Testing activities

• Two different type of testing:

– Transformation

• Objective: measure the technical feasibility and the effort

related to transforming the local data into the draft

INSPIRE schema.

– Application

• Objective: assess the benefits of harmonised data

specification from an end –user of from the application

point of view

13

INSPIRE Testing

Provision of interoperable datasets to open GI to EU communitiesJanuary 2008

• GIS4EU has participated in the INSPIRE Testing activities to solve

some questions from data provider :

– Which data sets are relevant to fulfil the INSPIRE data

specification?

– How they could be evaluated compliant with INSPIRE data

specification?

TWG activities

Provision of interoperable datasets to open GI to EU communitiesJanuary 2008

The TWG are working using the “Methodology for the development of data specifications” (D2.6 INSPIRE).

1. Use case development: identification and description regarding requirements for the data model

2. Identification of user requirements and spatial object types3. As-is analysis of the reference material provided by LMO and

SDIC 4. Gap analysis5. Data specification development: detailed description of the

application schema and feature catalog developed taking into account the requirements and analysis results

TWG Hydrography

Provision of interoperable datasets to open GI to EU communitiesJanuary 2008

In October 2008 was propose, by the INSPIRE Consolidation Team (CT), the first version of the conceptual model. The models realise, include in the GIS4Eu project, are related to the following themes:

• Administrative Units • Hydrography• Transport Networks

The project team decide to adopt it as reference conceptual model, a part of:

•Elevation theme

INSPIRE: Hydrography Model

Provision of interoperable datasets to open GI to EU communitiesJanuary 2008

Hydrography model is composed by 4 packages related among

them:

• Network: it derives from of Spatial analysis and

modelling use case

• Management And Reporting: it derives of the Reporting

use case

• PhysicaWaters: it derives of Mapping use case

• RelatedObjects: it consists of spatial objects related

with one or more use cases but they can not be

considered hydrographic elements
