IntroductionThe project is focused to recopilate some sources developed for applied mathematics and geographics information systems and more. At the moment the main development team "one person" is focused in his studies, trying to learn more about: mathematics, algorithms, parallel computing, data mining, systems biology, fluid dynamics, optimization and open source software developement, for stablish a contact you can write to: sigdevgroup@gmail.com or ajusworkopensource@gmail.com. Mesh Generation for Computational Fluid Dynamics (Warning in construction)After some time I feel really interested in the subject, specifically I research about parallel implemententions of meshing methods, at the moment I code the mesh stucture classes and methods. I will use for the parallelization the Boost.MPI library. In this project I make an extensive use of C++ templates, currently I facing the difficult task to chose a meshing algorithm that could be parallelized, here a link to the sources.
QgisSQLThe generic implementation of a SQL interface for Qgis is in qgisql, this project needs some help to grow in complexity. It's necessary to create spatial queries independent of the engine and also implement cross queries with multiple engines and qgis layers. The main unresolved problem is construct a better SQL parser an interpreter. Also we don't now if exist a standard spatial query language or something like a Spatial SQL standard that could be used independently of the DBMS. One possible ligth to find a solution is make a more deep analysis to the vector layer class definition of Qgis and the use of the spatial index library. The implementation has to be optimally parallelized because the size and load charge of the spatial queries. SIGCThere are some data base sources of the little project "Sistema de Información Geográfica Catastral" SIGC a data base for PostgreSQL designed with PL/PGSQL. The idea was create a data base to manage the "Cadastral" information of a provence, department or even a country. The objective is structure the information, generate statistics for land appreciation and future extension to land-use planning. This sources needs some fixes and extensions to be a complete productive data base. The code comments and data base definitons are in spanish. The work in SIGC is legacy at the moment we don't make any important modification. After some analyse to the SIGC conception we conclude that manage spatial information throught a SQL data base could not be the best option if we consider multiple user action, could be better a distributed file system data base. |
