This project is a implementation of a structure which uses a R-tree and the PostgreSQL DBMS to index geographic data associated with pre-aggregated data. The R-tree access method is implemented by the Arboretum library which implements a gamma of access methods in C++, but the R-tree is going to be modified in order to do less HDD accesses.

Along with Arboretum this project uses the QtLibrary to get full database abstraction. In order to access PostgreSQL data types the libraries from the source of the DBMS were included as well.

This project is the result of a Conclusion Course work presented to the State University of Londrina. The link to the article that describes the work done will be available here upon completion of it.
