These are some of Enhydris major features. Some of these are used in openmeteo.org/db, the free database with hydrometeorological data.
Some of the features bellow are used in openmeteo.org/db, currently most of these features are used in http://hoa.ntua.gr/ service. If you wish to obtain Enhydris to set up a database for your own, you can download-it freely from http://openmeteo.org/code/. By downloading Enhydris you get the whole of the available features, you have only to setup for each of them.
