The Social Tenure Domain Model (STDM) is a concept, model and information tool to map people-to-land relationships. STDM is developed and maintained by the Global Land Tool Network (GLTN) under the lead of the UN Habitat. The data model was closely aligned with LADM, an ISO standard on Land Management followed by most implementers. When it came to implementing the software tool the GLTN group decided against reinventing the wheel but to check out existing Open Source components (as maintained by the OSGeo Foundation) and Open Standards (as maintained by the OGC). So basically everything from the data model, technology standards and up to all the tools required to do proper Land Administration is already there. But it is too complex for non-technical people to grapple with. Therefore the GLTN group started to implement a software package which shipped with the right data model for the Postgres and PostGIS database, the desktop software QGIS, reporting tools and comprehensive documentation. This presentation will give an overview of the software tool and underlying components to give participants with limited technological background a better understanding of how it works and how they can also profit from the abundance of great Open Source software that is out there.
