|2015-03-13: das50-05_32-64_inst.exe General improvements (bug fix release, actually).|
|2013-02-04: das50-04beta_32-64_inst.exe bug fix release.|
|2012-11-12: das50-03beta_32-64_inst.exe Added "Vertical profile" panel for drawing a vertical profile of the scalar function for the nearest grid cell to the mouse click. Removed two unnecessary mouse clicks to get the cross section ready. Fixed a few bugs.|
|2012-04-19: das50-01beta_32-64_inst.exe provides new way of communication with the databases - DAS uses access to the data portal. Added support for Windows 64-bit and 32-bit operating systems.|
|2010-11-10: das45-03b_inst.exe Fixed bugs in interpolation procedure using data from several databases with identical IDs. (Thanks to Miguel Rodriguez Medina). Exported data both in .fdb and .csv formats now contain "server_id" information and therefore cannot be used in older version of DAS. Nevertheless, DAS can read the data, exported from the older versions of DAS.|
|2010-10-04: Access to the data from the SMHI SHARK database is back again! Thanks to Philip Axe, SMHI.|
|2010-09-13: Access to the SHARK database from the DAS is closed because the SHARK's web interface can not handle enormous amount of demands without problems. We are looking for a more robust solution. Sorry.|
|2010-08-31: das45-02_inst.exe Added access to several databases:
|2010-03-25: das44-12_inst.exe (beta) Added access to the NERI database using web interface (thanks to Ole Manscher, NERI).|
|2010-01-26: das44-11_inst.exe (beta) Multithreaded access to the distributed databases is implemented. Added support for Windows 7 themes.|
|2009-09-22: das44-10_inst.exe (beta) Added access to the IOW database. Thanks to Steffen Bock.|
|2009-07-08: das44-09_inst.exe (beta) Bug-fix release.|
|2009-04-14: das44-08_inst.exe (beta) Added proxy support for the database connection.|
|2009-04-08: das44-06_inst.exe (beta) Added support for the native look and feel. To support users without admin rights the default installation writes everything in the user's space only. Neither the installer nor DAS needs admin rights.|
|2009-02-16: das44-05_inst.exe Added support for users without administrative rights on Windows Vista.|
|2008-09-16: das44-04_inst.exe Support of local data (.fdb, .csv) in the older format (prior 4.4).|
|2008-08-17: das44-03_inst.exe is a bug-fix release.|
|2008-08-14: das44-02_inst.exe is a bug-fix release.|
For security reasons we have been forced to run the BED behind a firewall. We
The Data Assimilation System (DAS) coupled with the data portal is a remote accessible public information system for the Baltic Sea. Anybody over the Internet can get access to the data from the database by means of the Data Assimilation System. To use the DAS, you need a personal computer running MS Windows connected to the Internet.
Please, be aware that this software is distributed "as is". You can use it at you own risk. And, of course, you can not use either the DAS & AS3D software or data from the BED for commercial purposes.
To see what DAS can do, please, take a look at page Baltic Sea, which describes the hydrographic and chemical conditions in the Baltic Sea. All pictures and calculations presented there was contructed using the Data Assimilation System.
Run the DAS, select the database menu item and enjoy! The databases module allows you to use public data, supplied to us from virtually all institutes involved in measurements of hydrographical and chemical conditions in the Baltic (see: Data assimilation and nutrient budget calculations for the Baltic Sea - progress report, Jun-95). We have supplied these data for research purposes only. To use other data or for any other reasons feel free to contact us.
