The Ministry of Social Development of Uruguay (MIDES, , for its acronym in Spanish) is responsible for the national social policies. MIDES is also accountable for the coordination -at both sectoral and territorial levels- articulation, monitoring, supervision and evaluation of plans, programs and projects, within the areas of its competence, aiming at the consolidation of a progressive redistributive social policy.
The National Division of Evaluation and Monitoring (DINEM ) is a section of MIDES that oversees the monitoring and evaluation of plans, programs, actions, devices and social projects through the national territory. DINEM also produces and manages necessary information to improve their design and implementation.
The Department of Geography of DINEM is responsible for the production, management and analysis of geographical information,
Ever since the consolidation of the Department of Geography in 2012, we have tried to incorporate open source software to fulfill our duties. In particular, the management of an extensive field work, consisting in the annual implementation of approximately 40,000 visits to socially vulnerable households throughout the country. The objective was to conform a thorough georeferenced database of target households, in order to improve social policies implementation. Particularly, data was collected to enhance the scope of monetary transfer programs ("Asignaciones Familiares – Plan de Equidad" and "Tarjeta Uruguay Social"). The survey form applied contemplates social, housing, and environmental aspects.
Logistics to viabilize such fieldwork involved using statistical packages to manage the database generated, together with an intensive use of GIS to organize field trips and georeference relieved data.
Although proprietary software was implemented when the working process started, the development of the tasks themselves gradually demanded it to be converted to open source software. As the process as a whole became more computerized -incorporating a workflow engine and a PostGIS geospatial database-, license requirements and benefits offered by free and open source software (FOSS) options encouraged us to make the change. In that way, as the QGIS project was refined (fewer bugs and more functionalities), we were able to satisfy our needs using QGIS. PostGIS associated tools allowed the workgroup to rapidly coordinate the tasks needed to viabilize daily field trips, together with subsequent analysis tasks on the same data fieldwork generated, shortly after it was relieved and digitized.
In addition to information management and field work implementation, we constantly use QGIS typical geospatial tools to produce tematic cartography, and in spatial analysis tasks. This last, as much about the data that the fieldwork generates, as with other ministry programs information, and frequently even to aid interinstitutional projects. With "qgis2web" we were able to produce interactive maps, which have become the main way to communicate the results of such investigations. They allow human resources within other programs and agencies to easily and effectively manage higher amounts of information than with a collection of static maps, even when these resources are not used to reading spatial data.
QGIS has become a fundamental software to the Department of Geography at DINEM. It presents an excellent performance to work with heavy files and to interact with PostGIS and with our workflow engine. This allows us to have an excellent management of geographic data, which also makes for the production of basemaps and thematic cartographies of superior quality.
At the same time, extra features that are incorporated through plugins are of great value to us. For instance, the possibility of exporting "leaflet" map viewers, as well as incorporating high resolution satellite imagery directly into the GIS work area through “OpenLayers” to manually vectorize information, among others.
This variety of options is precisely what has allowed us to develop the specific and at the same time very different technical solutions that programs and agencies have been needing through past years.As mentioned in this article, we can state that QGIS meets the necessary requirements to be used in public administration as desktop GIS software. Also it has been a cornerstone in helping this institution to set up a web map, offering general population much information about social issues (SIG MIDES, OpenLayers based WEB GIS developed by the IT division).
