The telemetry data is also used to calibrate the instruments to provide for very accurate temperature readings. WXtoImg uses the telemetry data on NOAA APT images to very accurately calibrate the image, correct for non-linearities in signal strength, and make adjustments for gain changes across the pass. scanners) although there are limitations on what can be done. WXtoImg attempts to produce reasonable images from receivers which have too narrow an IF bandwidth (e.g. Output is in JPEG, PNG, BMP, PBM (PGM/PPM/PNM), or AVI format. WXtoImg has a built in set of image processing facilities, but can output raw images for further processing. WXtoImg supports both APT transmissions from polar orbiting satellites and WEFAX transmissions from geostationary satellites. Mercator), text overlays, automated web page creation, temperature display, and control for many weather satellite receivers, communications receivers, and scanners. WXtoImg supports map overlays, advanced colour enhancements, 3-D images, animations, multi-pass images, projection transformation (e.g.
