CERGOP2 Project
Data Retrieval – Partners Only
Central European Regional Geodynamics
Project Purpose: monitoring of crustal movements in the central part of Europe,
covering an area of 15 % of the continent, with the aim to determine the velocities of
selected points in seismic active areas over decades.
Partners (Austria, Bosnia-Herzegovina, Bulgaria, Croatia, Czech Republic, Germany,
Hungary, Italy, Poland, Romania, Slovakia, Slovenia, Ukraine) + EU
Duration: 2003-2005
Connection CEGRN Consortium – http://www.fomi.hu/cegrn
GPS observations (stations, campaigns);
GPS solutions (SINEX, normal equations);
Other observations;
Non public results;
Non public papers;
(Form sheets + PHP scripts generating active links to servers).
Realization
Front-end:
HTML forms;
PHP scripts accessing meta-database;
Generated HTML pages for info download or direct access (ftp, http).
Middleware:
Meta-database at central server;
Robots for information search of different servers;
Scripts updating meta-database.
Backend:
Backup (disk array) of central server;
ftp- and http-servers at different locations (distributed data holding).
Meta-Database
•Relational database, organized in tables;
•Primary key: station code + domes number;
•Access by SQL statements;
•Extendable to stored procedures (e. g. transformations);
•PostgreSQL or MySQL.
