Modelagem de cadastro territorial com base no Modelo de Domínio para Administração Territorial (LADM): o caso do Sistema de Informação Territorial de Fortaleza (SITFOR)

Abstract

The Multipurpose Cadastre (CTM) is configured as a strategic infrastructure for territorial governance, by integrating data of different natures and supporting public policies in multiple areas. In this context, the Land Administration Domain Model (LADM – ISO 19152:2012) stands out as an international reference for the standardization and interoperability of cadastral systems. This article analyzes the modeling of the Fortaleza Territorial Information System (SITFOR), implemented in 2013, based on the LADM and the OMT-G modeling technique, highlighting its evolution, customizations, and integration into municipal administrative processes. The results indicate that SITFOR overcame the fragmentation of sectoral cadastres by structuring an integrated database of fiscal, legal, territorial, and urban information, becoming an essential support for initiatives such as the Digital Licensing system, interoperability with state and federal databases (RedeSIM, reference value for the Inheritance and Donation Tax – ITCMD, and the National Territorial Information Management System – SINTER), and the use of spatial analysis tools to support public policies. These integrations significantly expanded the use of cadastral data by public administration, consolidating the system as a core articulator between urban planning, taxation, environment, and strategic planning. The study also highlights challenges and prospects for improvement: (i) full integration between spatial and alphanumeric systems; (ii) representation of formal and informal situations at different topological levels, as recommended by the LADM; (iii) evolution of taxpayer linkage rules in the GRPFOR, to identify all persons related to land according to their rights, restrictions, and responsibilities; and (iv) development of mass editing tools to streamline cadastral updating. It is concluded that SITFOR represents an innovative experience in Brazil, aligned with international best practices and the national guidelines for CTM. Its evolution towards 3D cadastres and the incorporation of Digital Twins positions Fortaleza as a reference in municipal land administration, reaffirming the transformative potential of the cadastre as a hub of territorial intelligence.
