During this presentation, we will talk about the Geographic Information System of the State of Tocantins (Brazil). This GIS has been developed and implemented for the storage, organization and sharing of geospatial data. It includes the development of a multiuser system for the storage, visualization, analysis and download of geospatial data / information and statistics, integrating several repositories of geographic data.

This project deals with the development and implementation of an information system for the storage, organization and sharing of geospatial data produced by the State of Tocantins Finance and Planning Secretariat (SEFAZ-TO). The project includes the development of a multiuser system for the storage, visualization, analysis and availability (download) of geospatial data / information and statistics, integrating several repositories of geographic data. The State of Tocantins opted for use of open source software, based on the gvSIG Online platform, for the implementation of Spatial Data Infrastructures, which integrates components such as the GeoServer map server, the WebGIS OpenLayers client and the PostgreSQL / PostGIS spatial database. The system is adaptable to any type of computer or mobile device connected to internet (responsive) and compatible with the most modern versions of internet browsers. The software architecture allows the data visualization in a distributed way, and in different projections and coordinate systems. These data can be available on Web services or direct access, through URL stored in the metadata catalog. In addition, GeoNetwork has been used for the metadata structure, sharing reliable information about the source data. In order to provide greater geostatistical functionality, a series of tools have been developed, allowing the visualization and download of different types of graphs (bars, circles and lines). A relevant part of the project was the cataloging and registration of geospatial and statistical data, orbital images, as well as thematic maps and technical documents in pdf format available at SEFAZ-TO.
