Land Planning in Region Veneto (Italy)

• Region Veneto rules the spatial planning using a standardized and «official» GIS data model.

• The «official» GIS data model is applied mainly for land plans of municipalities.

Land Planning Act of Region Veneto (Italy)

• Municipalities have to compile their Local Land Plans (PRC Piani Regolatori Comunali) using a standardized GIS data model. They must use the shapefile format for the geometries.

Land Planning Acts of Region Veneto (Italy)

• L.R. 11 (2004) - Norme per il governo del territorio (Rules for land planning)

• Dgr n. 3178 (2004) - first release of GIS data model

• Dgr n. 3958 (2006) - the workflow of data validation

• DGR 3811 (2009) - latest and improved release of GIS data model

Synthetic Data Flow Schema

The Data Model of Region Veneto

• The GIS data model specifies the required feature classes (geometry types, field types of the database, primary keys) and metadata.

Validation of the GIS data

• The Veneto Region has immediately activated a system for the validation of the GIS data of Plans coming from Municipalities. The system computes two indices to measure the compliancy of the incoming data with the data model according to art. 11 of Law n. 11 (2004).

Index IQ & ICQ • IQ - The Quality Index measure the compliancy of the

primary keys and the metadata. • ICQ - The Comprehensive Quality Index is about the

geometric and topological consistency of the features.

The procedure – Step1. Data import into a geodatabase structure

and Logical, Database-level Validation. The procedure has been developed using Visual Basic NET and Oracle,

– Step 2. GIS analysis and GIS validation. The software procedure has been built on top of Intergraph’s GeoMedia GIS software using GeoMedia Fusion. GeoMedia Fusion is the add-on module of GeoMedia GIS for data validation and schema remodelling and it has been extensively tested by the involved data providers during two INSPIRE-related and EU-cofounded projects: GIS4EU and NatureSDIplus.

GIS Validation Requirements: • validation of geographical feature classes

according to the data model and rules of Region Veneto;

• management of specific rules for features to be validated, tests to be performed, routines to be applied, and parameters for validation;

• capabilities of reporting using graphical queues to analyze results and send a feedback to Municipalities for recovery of anomalies.

Queued Edit

The SDI of Region Veneto • Currently the whole

procedure for Local Land Planning is coherent with the SDI of Region Veneto - operative since 2011.

• The SDI shares data and geographical web servicies to Municipalities for land planning purposes.

Geographical Information and e-Government in Italy

• The National Law for e-Government “Decreto Legislativo 7 marzo 2005, n. 82, Codice dell’Amministrazione Digitale” and the following modifications and intergrations (the latest

intergrations are in the D.L. 18 ottobre 2012 n. 179); • The INSPIRE Directive; • The Italian Law full implementing INSPIRE

Directive “Decreto Legislativo 27 gennaio 2010 , n. 32 Attuazione della direttiva 2007/2/CE, che istituisce un’infrastruttura per l’informazione territoriale nella Comunità europea (INSPIRE)”

The new workflow for the GIS component of local land planning in Region Veneto The leading concepts are the following: 1.All data exchange must be provided by SDI according to INSPIRE rules. 2. The Municipalities will be capable of validating autonomously their GIS datasets using a web service – based procedure provided by the Region SDI. 3.So the data uploaded by Municipalities into the Central GeoDatabase of Region Veneto’s SDI will be ready for automated mosaicking, remodelling (using local data models and INSPIRE Land Use data model) and SDI-sharing.

Towards a new model of planning

• The availability of real time updated GIS data coming from Municipalities and the other public bodies involved in INSPIRE (River Basin Authorities, Environmental Agencies, Multi-utilities Companies, et cetera) will allow the Directorate for Land Planning and Landscape of Region Veneto to implement a new model of planning based more on monitoring the real dynamics of phenomena (human pressure against the environment, urban sprawl, risk of natural/industrial disaster) than on controlling indicators suited to capture dynamics of the past economic phase (evolution of settlements, urbanization).
