Contrail is an enterprise-level software solution for the real-time data collection and visualization of data used in Flood Early Warning (ALERT/ALERT2), Dam Monitoring and Reservoir Operations, Road Weather (RWIS), Irrigation and Water Accounting, Stormwater Management, and more.

Contrail collects, processes, and validates data in real time from virtually any sensor type and transmission protocol. The software, compatible with Campbell Scientific equipment, provides web-based operational decision support and early warning notifications via pager, email, and text message. It is designed to meet the demands of mission-critical applications, providing up-to-the-minute visualization of current conditions and presenting data in easy-to-understand, high-resolution maps, dashboards, charts, graphs, and tables. Contrail is fully web-based and enables users to view, manage, and analyze real-time and historical data in one place.

Contrail is easily configurable for diverse users, providing data that may have to meet and serve the needs of many different applications—whether for flood early warning, dam safety operations, road-weather condition monitoring, stormwater and water quality, or public information. With Contrail, you can control access to the data set that each user or group of users can see and expose different data sets to different sets of users, so they see what is relevant to them.

Contrail is available from OneRain as licensed software to purchase and operate locally on your organization’s own network, and as a cloud-based hosted and managed application.
