The lack of forest management, the excessive land fragmentation, the rural exodus, the escalation of forest fires, among other reasons, led to the Resolution of the Council of Ministers n.º 178/2003, approving the main guidelines of the structural reform of the forest sector. In August of 2005, the government approved the legislation that establishes the creation of Forest Intervention Zones (FIZ), Decrees-law n.º 127/2005 and n.º 15/2009 (revision), as a mean to solve those problems. One of the structural elements required for the creation of a FIZ is the existence of a real property cadastre, geometric or simplified, of all the members parcels or in the absence of it, an inventory of the property structure in a appropriate scale for its identification. However, due to the lack of cadastre for approximately half of the territory, there might be the need to acquire cadastral data of the forest holdings with the exclusive purpose of creating a FIZ and that is often not considered as real property cadastre. From the early 90’s until the present, about 169 Forest Owners Associations (FOA) have been created to assist forest owners in the sustainable management of their forest holdings. To overcome the lack of cadastral data, we intend to evaluate the possible contribution of the FOAs for the land register execution in FIZs in the scope of the National System for Managing and Exploring Cadastral Data (SINERGIC). Several FOAs were asked about the methodology used to perform parcel surveys and their interest, in exchange of mutual benefits, in adopting the SINERGIC technical specifications in those surveys. The main objectives are the harmonization of the data collected by all FOAs, the creation of a unique and seamless database with the attributes required for the characterization of all parcels within a FIZ, and consequently the inclusion and/or update of those parcels in the Portuguese real property cadastre. To collect data in the field, an application, thought to be used by all FOAs as a standard, was developed with the free CyberTracker software. This application, which might be installed in a smartphone or a PDA, allows real time collecting of the vertices of the property borders (with a GPS attached) and also the insertion of the attributes for each parcel characterisation directly in the field. This procedure enables not only a faster acquisition of data but also the collection of both geometry and alphanumeric data in digital format, which constitutes an added- value for the implementation of the real property cadastre. The data collected with this application might also be integrated in the land registry offices, tax offices and city councils databases.
