SiNErGIC : a new approach to cadastre
Juliao, Rui Pedro et al.
Portugal is known to be one of the last countries in Europe where there is no official geometric registry of parcels. Taking advantage of starting behind others we created SiNErGIC project incorporating knowledge from other countries. As we all know a true, updated, geometric definition of parcels is an important asset to support policy making, planning and land management, as well to promote nationss sustainable development. Moreover, it promotes equity in tax policy and collection and it can support several added-value activities and spare a lot of tax payerss money by providing all necessary information for public organizations to act. Taking this under consideration, the Portuguese government decided to start SiNErGIC project. SiNErGIC is a project, started in 2005, that created a common platform regarding cadastral information. This project, based in a spatial data infrastructure (SDI) philosophy, integrates in a single infrastructure the cadastral, land registry and fiscal information systems, putting them to work together. This paper presents all the rationale behind SiNErGIC project, its development, and also the evaluation of its first results. The first part of the paper will present the context, the reasons for SiNErGIC development and also the main development axis of the project, including the cost-benefit analysis results. The second part is dedicated to present the information system that is supporting data maintenance and exploitation. The third part of the paper will present the methodology for data acquisition and the results obtained from the first operations done through a call for tender issued in September 2009. Finally, it is going to be presented future actions to keep SiNErGIC updated and as a key useful tool for Portugal. We consider that SiNErGIC, being developed with this new conceptual framework, and promoted by a small country with limited resources, can be an inspiring model for other countries, namely developing countries.
