Wxtoimg program3/30/2024 ![]() Accurate temperature calibration on IR images is also performed. On GOES satellites, the grayscale is used to correct for non-linearities in signal strength and normalise the image. 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. WXtoImg can read AU, WAVE, and raw linear PCM audio files. 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. WXtoImg also provides a large number of image processing functions and contrast enhancements for weather satellite images. SYNOPSIS xwxtoimg wxtoimg ]] ] infile DESCRIPTION WXtoImg converts an audio file recording of a weather satellite audio signal to the image it represents. WXTOIMG(l) WXTOIMG(l) NAME WXtoImg - program for decoding weather satellite signals.
