LADM_CP_Colombia_Development and Employment of an LADM Implementing Toolkit in Colombia
Lorenz Jenni, Andrés Guarín López, Stefan Ziegler, Víctor Manuel Bajo Pérez
The Swiss Government is currently financing a project which provides technical assistance to the Colombian institutions in order to establish the conceptual and technical bases of a modernized land administration. This paper explains the data modelling process and methodology applied by the project for adopting the ISO19152 (Land Administration Domain Model) in Colombia and for describing the LADM country profile using the Conceptual Schema Language INTERLIS, as well as the development of specific Free and Open Source Software tools that support the countrywide implementation of the standard. The project’s Model-Driven Approach responds to the conceptual framework of the Multipurpose Cadastre defined by the Colombian Government, where the operation of the cadastre will be delegated to third-party operators by applying a “Freedom of Methods” principle. Because of this principle, a system independent data exchange mechanism is needed, a requirement that INTERLIS meets. With the developed Data Validation Tool and its integration in a web service, data delivered by the cadastre operators is checked against the LADM-COL model. With the defined, well-documented and successfully applied modelling process, methodology and deployed tools, a LADM Implementing Toolkit is at the disposal of countries that face similar challenges as Colombia in modernizing their land administration.
