About

Weather, mapping and software.
Built by people who know the work.

Signal4D is a weather intelligence and geospatial situational-awareness company. We fuse the world’s weather and environmental data with the infrastructure, assets, and people our customers operate — then monitor, predict, and alert on the conditions that put them at risk.

Why we built Signal4D

The forecast needs to reach the people making the call.

A forecast is useful when a team can connect it to the line, route or site it is responsible for. We built Signal4D to make that connection visible, and to keep operations and field teams working from the same information.

Our platform is built by a team that has designed, built, and operated global, high-scale software across mapping, weather, and connected-vehicle systems — bringing deep experience in distributed platforms, geospatial data, and real-time alerting.
