The Universal Radar Format (.URF) is used to normalize different sources of radar data before it is translated into the optimized form used within Radar ViewPoint. The programs CDR2URF and PRERADAR both produce URF files and the program MAKERADR takes an URF file to produce the .RAD file used by Radar ViewPoint. The URF file is a standard text file and can be created, edited, viewed or printed by most any text editing or word processor programs.
There are circumstances where you have, or can get, radar data on a printout, but the data is not obtainable as a file. If you have the desire and the patience, the radar data can be hand entered and then used by Radar ViewPoint. To do this, you must create a text file organized using the Universal Radar Format, then run the MAKERADR program on your text file. The text file can contain just a few radar hits, or up to tens of thousand of radar hits.
The Universal Radar Format uses fixed field locations and is described as followed:
