Water Inventory Data Management System (WIDM) - Overview
WIDM is dynamically connected to the provincial Environmental Monitoring System (EMS) and the Continuous Monitoring System (CMS). This interactive sharing allows use of existing resources available within these corporate applications. WIDM uses common data elements with EMS for station information and parameter information. The Ministry standard is that all measured parameters need to be created and maintained within EMS. Because of this, there is no provision within WIDM to create or alter parameter information. It is understood that all proposed WIDM parameters are compatible with EMS standards and current EMS parameters: they will be created through EMS as needed.
Using CMS, the architecture incorporates the ability to automatically poll information directly from telemetry sites using modem, ftp or telnet protocol. WIDM also has the ability to load time series files obtained by manual download methods.
