UPDATE – August 2022

DTN has introduced the concept of dimensions to our web mapping service Flight Hazard layers and other Aviation-specific layers to simplify the number of individual layers that need to be managed and provide increased flexibility for usage. Users can pass the simplified layer name, requested dimension and the forecast time they require and receive the proper image in return.
