RULES
Compares critical thresholds (rules) against forecast for
determination of weather impacts on various systems
(weapons, sensors, personnel, sub-systems)
Threshold

MyWIDA v2.1 Web Services
• Area Of Interest Service (AOIS) – Allows user to request
forecast gridded weather model data for a specific region
and time duration.
• Threshold Evaluation Service (TES) – Evaluates an
environmental threshold (e.g., wind speed > 15 kts)
against a grid of environmental data and returns the
results of 0 (false) or 1 (true) and are eventually
translated into red/amber/green
UNCLASSIFIED
MyWIDA v2.1 Web Services
• Rules Evaluation Service (RES) – Evaluates a system rule
(one or more thresholds) against a grid of environmental
data and returns the impact level (e.g., marginal or
severe)
• Impact Overlay Service (IOS) – Creates a Keyhole Markup
Language (KML) string from a grid of impact level(s) for
display via a map server (e.g., Google Earth, OpenLayers,
etc.) in 2D or 3D

Customization
• Some situations/equipment
require forecast resolution
not currently available
• MyWIDA v2 will allow a user
to “fat finger” input data
• Allows for real-time
response
Can be supplied with customtailored rule sets for special
users/applications (e.g., Aerostat,
UBE, IED, etc. rules)
