Wind Maps View larger image of data points Maps produced by the Illinois Wind Program were built upon using the Kriging interpolation method. The wind map grids have a resolution of 300ft x 300ft. Three major data sources were used in creating the wind maps: Data collected from the Illinois Wind Program (22 Sites) National Weather Service (48 Sites) Illinois State Water Survey (19 Sites) for a total of 89 data points around the State of Illinois. The maps use a Natural Breaks (Jenks Optimization) classification method broke down in ten different classes ranging from 5 mph to 28 mph. The maps use the same classification for all 10m, 50m, & 80m maps, thus showing how wind speeds increase as you increase in height.
