1 An open-source based SDI for local spatial planning compliant to policy requirements, Istanbul G. Martirano, V. Gagliardi, F. Vinci (Epsilon Italia) M. Gaccione (Province of Cosenza)

2 SUMMARY Policy requirements Enhancement of the existing local SDI Data model Procedure for the on-line editing Webgis Conclusions

3 POLICY REQUIREMENTS The spatial planning in the Calabria Region (Southern Italy) is governed by the Regional Law n 19/2002 and its associated Guidelines (2007), which set the rules for an harmonised spatial planning at the three different interlinked levels: regional, provincial and council. Because it is not straightforward to univocally translate these rules into operational tools and procedures to be applied by the spatial planners, the development of a common data model is needed.

4 ENHANCEMENT OF THE EXISTING SDI In order to support its 155 Municipalities in preparing their Council Structural Plans (spatial plans at council level), the Department of Spatial Planning of the Province of Cosenza has enhanced its existing SDI, developing the following three additional components: A data model for the Council Structural Plans (PSC) A procedure for the PSC on-line editing A webgis for the consultation of the PSC

6 Objectives DATA MODEL To develop a data model for the Council Structural Plans to be proposed as a reference standard for the Municipalities, focusing om the thematic layers and their attributes, in adherence to the Urban Law of Calabria Region and its Guidelines and to the outcomes of the Technical Committee for the Geographic Information System and Observatory of the Urban Changes of the Calabria Region. To develop a webgis based procedure to enable the Municipalities to prepare their Council Structural Plans in conformity to the propsoed data model. to optimise the process of the Department of Territory Planning and Management aimed to verify the compatibility of the Council Structural Plans with the Coordination Territorial Plan of the Province.

7 DM DEVELOPMENT STATUS Phase 1, started in Dec and completed 15 June 2012 Conceptual data model for the Council Structural Plans created encoding the textual/conceptual rules set by the above mentioned policy requirements Logical data model drafted in excel format Physical data model drafted in shapefiles Physical data model generated using a PostGis geodatabase Draft version of data model tested by 8 pilot Municipalities Data model finalised after intense and fruitful consultation between the participants to the testing and released version v4.5

9 DM DEVELOPMENT STATUS Phase 2, to be completed in October 2012 Full application of the finalised version of the DM to 8 Council Structural Plans Formalisation of the logical data model in UML Creation of a gml application schema (xsd) Adoption by law by the Regional Government Phase 3, to be completed in December 2012 Creation of the mapping rules for schema transformation into the INSPIRE Land Use DS v3.0 Remapping of the available spatial datasets and metadata Network services deployment

12 Webgis based procedure for the on-line editing Use of an open source GIS desktop client to edit the plans in conformity to the proposed standard Server-side implemented architecture: use of the open-source web server Geoserver Enabling of the WFS-T protocol on the PostGis geodatabase Client-side implemented architecture: Use of QGIS open source GIS desktop client Creation in Python environment of custom forms for the geodatabase population, encoding all the codelists and the constraints present in the data model Creation of QGIS stylesheets

16 WEBGIS In order to allow the consultation of the Council Structural Plans generated in conformity to the data model it has been created a dedicated webgis, using the open-source Mapserver/pmapper platform, integrated in the existing geoportal

21 CONCLUSIONS Some advantages of the implemented local SDI for spatial planning compliant to the policy requirements: the use of a common data model which facilitates spatial analyses that can be made on harmonised datasets; these analysis are useful to perform territorial benchmarking and compatibility checks of the council plans with the provincial and/or regional spatial plans; the use of the on-line editing procedure, which ensures contextually to the editing phase - the compliance of the spatial plan against the policy requirements, avoiding further efforts and costs related to transformation and validation processes.

22 Some advantages of the adopted methodology: Inspired by INSPIRE in terms of: transparency of the process consultation with stakeholders CONCLUSIONS formalisms progressively evolving towards INSPIRE compliance roadmap for the adoption by law Fully in line with what we learnt yesterday in the Panel Discussion in the Plenary session let s go at regional and local level
