It was designed for use during the early stages of my satellite receiving activities, when clouds and interference prevented easy identification of what I was actually observing! Therefore WXtrack can read processed satellite images from one or more folders of your choice, and present these images side-by-side with the ground track prediction. To make visual correlation easier, minute markers are produced on the predicted image to match those on NOAA APT transmissions. Map overlay images suitable for subsequent combining with actual satellite pictures can be produced.
