Tideda – Time Dependent Data

Introduction
Tideda is a software package for making databases to store and analyse any time series data. It is particularly suitable for processing environmental and hydrological data. Tideda evolved from a hydrological database system first developed in New Zealand in 1969. It has been continuously developed and used ever since, making it amongst the most durable software in the world.
National Institute of Water and Atmospheric Research (NIWA), is the organisation that develops Tideda. NIWA is a research organisation, approximately 70% of NIWA’s income comes from bidding for NZ Government research contracts. NIWA runs New Zealand’s national hydrological, environmental and ecological databases. It has 14 regional field teams that collect, quality assure and archive data using Tideda. Most provincial authorities around NZ also use Tideda.

Institutional Advantages for using Tideda
NIWA is not a software company. Tideda is a core product for our own use and as such we are continuously improving and developing it. These developments are passed on to our customers free of charge. The software is always rigorously tested by our own scientists and field teams before it is released to customers. This ensures the highest quality and reliability. The software is based in solid science, the scientists who contribute to Tideda’s development are world renowned e.g. Dr Richard Ibbitt, chairman of the Regional Steering Committee for UNESCO’s International Hydrology Program (IHP) in SE Asia. Dr Ibbitt has been involved with the development of Tideda since 1970.
