Hydroelectricity and Transmission Planning in Chile Use Open Source Geospatial Tools

We were able to leverage a number of open source geospatial tools, such as QGIS, GDAL/OGR, and the PostGIS extension to the PostgreSQL open source relational database, in order to control the quality of the geospatial data at hand. These tools also helped us carry out the types of spatial analysis necessary to determine relationships between the various objects of value and, on the one hand, the potential hydropower projects, and on the other, the possible alternative transmission corridors. The key to hydroelectric capacity planning in Chile is the ability to generate the maximum amount of electricity, given certain restrictions, while assuring a fixed level of interaction with objects of value.
