QGIS, PostGIS, LADM - in the Land Administration Course developed by IGAC

In the convergence of different initiatives, aspirations and challenges that Colombia is experiencing to maintain leadership in the southern cone in geospatial matters, between July 27 and August 4, the Center for Research and Development of Geographic Information - CIAF of the Geographical Institute Agustín Codazzi will develop the Course: Application of the ISO 19152 standard (Land Administration Domain Model) and the use of the INTERLIS language in the framework of Spatial Data Infrastructures.

The justification is more than evident, since the Land Administration is an issue that has taken high priority in many countries, caused by various social, economic and environmental causes. The technological boom since the 90 years extends the range of possibilities to offer new and better services on spatial data and property rights, taking advantage of the potential of connectivity mechanisms, spatial databases, computer programs and equipment. The pressure for this technological offer and the demand of public and private institutions, is balanced by the use of standards; Within this framework, the 2014 Catastro initiative was created in the 1995 year, and part of its materialization in the ISO 19152 Standard in the 2012 year.

Several countries worldwide are currently seeking to implement the LADM in their Cadastre, Land Registry and Spatial Data Infrastructure systems. INTERLIS is a language that has proven to be efficient in the creation of tools and methodologies to facilitate the interoperability and transfer of geospatial information.

Colombia is one of these countries, which, in the context of social, legal and institutional reforms, plans to take advantage of the potential of LADM as a transversal axis for the modernization of territorial management. Currently the national profile has been developed, proposals for specialized profiles and tools using the INTERLIS language.
This context justifies the need for the Agustín Codazzi Institute to integrate within its academic offer a course that may be available to professionals of the earth sciences, involved in the different stages of the territorial management cycle under an integrated approach.

In the end, the participants are expected to have technical and cognitive skills in the participants in Spatial Data Infrastructures and in the domain of the LADM land management standard using the INTERLIS language to create tools and methodologies that facilitate their adoption and implementation.

Definitely the course is not only important, but it is also interesting because of the combination it has between the theoretical approach and practical exercises. The duration is 32 hours, in four days distributed in two weeks (Thursday and Friday) and is structured in three blocks:

  • Generalities, which include basic concepts about administration with a focus on international trends and challenges of the 2034 Cadastre, spatial data infrastructures, international geographic information standards and databases.
  • The second block includes the theoretical foundations of the LADM, the Colombian profile of adoption of the ISO 19152 standard and use cases applied to Cadastre, Property Registry and Territorial Planning. Also in this block they introduce the principles of the UML modeling language.
  • In the third block, the construction of a simplified model of LADM is worked on following the proposed workflow when using INTERLIS, from its semantics from the code, to using tools such as UML Editor and ili2pg, with which a data structure is constructed Geographical information about PostgreSQL / PostGIS, generation of data in the model using a QGIS plugin, export, validation and loading of data until its visualization from a spatial viewer.

In short, it is an interesting effort that this time has the support of the Economic and Development Cooperation (SECO) of the Swiss Embassy.

    I'm still geofumed and I'm waiting for information on this land administration course.

  2. Good Morning.
    The Plug-in is being developed by the Project for the Modernization of Land Administration in Colombia, by the Secretary of State for Economic Affairs (SECO) of the Government of Switzerland, together with a Canton of the Confederation, since in Switzerland use INTERLIS as the standard of exchange and modeling. The Plug-in will be open source, free and free and can be freely downloaded for QGIS.
    It is designed for the edition of data related to the Land Administration in a very specific environment: it is based on a data model (classes involved, their relations and constraints imposed), in the case of Colombia, LADM-COL, with the Which builds the editing environment, providing an interface that facilitates editing based on the model's needs. It also works in the data validation and exchange environment.

  3. Hello, I would like to know more information of the plugin, this can be freely accessed, as I can download and test the plugin

  4. Good, some kind of publication about the course, I'm from Argentina I'm interested in the subject
