FAQ
PPI to PGM Conversion
What are PPI files?
PPI is a product file of IRIS (Interactive Radar Information System), the weather radar software of Vaisala, which is used by weather services in many countries. PPI stands for Plan Position Indicator, the classic radar picture in which the antenna sweeps around the compass at a fixed elevation angle and the echoes are shown on a map centered on the radar. A file of this type holds such a picture for a quantity such as reflectivity, which shows the intensity of precipitation, radial velocity, which shows how fast the air moves toward or away from the radar, or the width of the velocity spectrum. These images are the basis of weather surveillance, storm tracking, and short-range forecasting, and the same family of files also includes products like rainfall accumulation and echo tops.
What are PGM files?
The PGM or Portable Graymap format is part of a package of open source graphics programs called Netpbm. Other Netpbm formats include PPM (Portable Pixmap) and PBM (Portable Bitmap), also known under the collective name of PNM (Portable Anymap). A PGM file includes a grayscale image, can work on a UNIX platform, as well as on Windows or Mac OS X, and can render a scope of up to 255 grayscale colors.
