Geo-Database

The Geographic Information Systems are tools that allow you to pull in a short time and so versatile useful information in decision-making, from a significant amount of data. The added value is primarily bound to the explicit consideration of the spatial dimension of decision-making problems, inherent characteristic to issues relating to the development, processing and management of the territorial and urban system.

The geographic database, or geodatabase, is now an essential component for complex GIS applications, especially in the working groups large and heterogeneous. In this field, the most powerful and reliable solution Open Source is PostGIS (www.postgis.org), an extension to the PostgreSQL relational database to manage the storage and management of geographic data. It is a free database which, based on OGC standards, it makes an excellent solution for those who seek interoperability between desktop applications, analytical and Web in the field of GIS. It allows multi-user access to large amounts of data, both geographical and alphanumeric and managing relationships between them, ensuring their integrity. It allows the management of three-dimensional data and walks towards that of the raster.

Advantages

  • Efficiency in the use of models and data analysis;
  • Support complex decision-making processes;
  • GIS Stand Alone (QGIS) and web (WEB-GIS) interactive;
  • Ease of use within the reach of all users;
  • Extraction in a short time and in a versatile way of information in decision-making, from a significant amount of data;
  • Analysis using dedicated tools (developed on request if not available) on a specific area of interest;
  • simulate possible scenarios
  • multi-user management, data analysis, queries, printing reports and maps.

How it Works

The geographic database helps the user decide better; it is not only a computer application, because it also contains business intelligence tools and Expert Systems technologies, such as decision support models.

Technologies

qgis-iconQGIS is the best GIS tool in the free and open-source software (FOSS) community. QGIS is a user friendly Open Source Geographic Information System (GIS) licensed under the GNU General Public License. QGIS is an official project of the Open Source Geospatial Foundation (OSGeo). It runs on Linux, Unix, Mac OSX, Windows and Android and supports numerous vector, raster, and database formats and functionalities.

 

download  POSTGIS, is an open source software program that adds support for geographic objects to the PostgreSQL object-relational database. PostGIS follows the Simple Features for SQL specification from the Open Geospatial Consortium (OGC).

 

Who is it for

To all those who need to organize, edit, manage, and perform operations on geographic data to help make decisions.
