Overview
WeatherSentry® Web Services from DTN provides your organization with the highly accurate weather observations and forecasts relied on worldwide to protect people, resources and profitability. These forecasts are top ranked by the independent agency ForecastWatch.com as the most accurate among industry providers.
Our global weather observations and forecasts empower situational awareness applications by providing a clear view of near-term forecasts, and current and recent weather, including valuable weather content not often available through other services (such as lightning strikes). With our highly accurate, web-delivered weather data, you can optimize operational decisions through improved visualization, by integrating valuable GIS or point-based weather data into your critical applications and websites.
Map layers
We have over 1,200 layers that can be directly integrated into your geographic information systems (GIS) or simply layered on top of a basemap. If you are looking for discrete geospatial weather data that you can integrate with other spatial assets, or if you are simply looking for a visualization of current or past data, we have it. Some of the more popular layers are listed below:
-
Lightning (updated at least every 5 minutes)
-
Storm corridors (updated ~30 minutes)
-
Weather station observations (updated ~60 minutes)
-
Severe weather bulletins (as provided)
-
Storm reports (as provided)
-
Tropical storm forecasts (as provided)
-
Radar (observed precipitation) (updated ~30 minutes)
-
Satellite (clouds) (updated ~30 minutes)
-
Precipitation forecast (updated ~30 minutes)
-
Pavement temperature observations (updated ~30 minutes)
What type of layers do I need?
Our layers come in two flavors. Our web mapping service (WMS) serves up image tiles that are laid on top of a basemap and rendered (e.g. radar is a good example of this). Our web feature service (WFS) delivers each of the weather data elements as specific features with rich attribute information. Choose a service type based on your specific requirements.
| Layer Type | Application | Best for… |
|---|---|---|

Web Feature Layer (WFS Service) |
Integration with other spatial assets |
Simple to sophisticated query and analytics using recent or current weather data. Understanding precisely where a weather element is in relation to other spatial features around you |
Both services provide weather content according to OGC (Open Geospatial Consortium) standards.
