DATA SPATIAL INFRASTRUCTURE (DSI) FOR THE ANALYSIS AND STUDY OF ENVIRONMENTAL RISKS: AN EXPERIENCE IN SOUTHERN OF ECUADOR.

In this work, we apply the concept of Spatial Data Infrastructure (SDII) in order to create a tool to study and analyze risk and environmental variables. This system will also support decision making for a sustainable environmental management in southern Ecuador. To develop this system, we used Open Source tools such as: Apache Server, MapServer 4.6 and OpenGis standards for publishing georeferenced information on the Internet. The thematic information has been collected from different development organizations. Most of this information is derived from satellite images such as ASTER, LANDSAT; and MODIS. The system also allows for the display of geographical information, associated thematic data query and download of different thematic layers
