Program is the largest tool from the HydroOffice software package. It is designed, for example, for time series processing (discharge, groundwater level changes, temperature, precipitation, wind speed). This unique software is the flagship of the HydroOffice software package. TS Editor, version 3.0, contains more than 2,000 functions for managing time series. You can execute these features from the ribbon toolbar, using the functional tree in the side panel, or with the very simple and fast scripting language from the command line. Most of these features can be found in the group of conversion commands. Comparing TS Editor functionality with other existing software, this program is situated on the border between spreadsheets, statistical tools, databases, visualization software and all various highly specialized professional tools.
