Using NTAP Data from ARTCC


This procedure assumes you are able to obtain data NTAP data from an ARTCC facility into the computer. How this is done is beyond the scope of this procedure; but some facilities will use a 9-track tape as the transfer mechanism between the center's computer and a PC. Some centers have the capability to produce an NTAP onto a floppy directly from a PC connected to the main system.

Load the NTAP file into your /RADARVP subdirectory. The file now needs to be translated into Radar ViewPoint's optimized radar data file format (.RAD file) ...

NTAP file to Radar ViewPoint format

The following example assumes the NTAP data file is named NTAP.TXT and the Radar ViewPoint data file will be named NTAP.RAD. You can use any name you like, but we do recommend the .RAD filename extension be used for Radar ViewPoint optimized data files.

At the DOS prompt (you may use a DOS session under Windows):

  1. Convert NTAP.TXT file to a universal radar format file (NTAP.URF) by typing:
          PRERADAR  NTAP.TXT
    
  2. Convert universal radar format file to Radar ViewPoint optimized file by typing:
          MAKERADR  NTAP
    

You may now use Radar ViewPoint to view the radar information. While in Radar ViewPoint, pick the Open... command from the Radar menu and select NTAP.RAD. You may need to zoom to the area of the radar information to get a good look at the data...good luck.

Viewing Several NTAP Reports Together

It may be advantageous to look at several NTAP reports at one time. This is done simply by merging the universal radar files together before using MAKERADR. Here is a sample of merging four NTAP files together: At the DOS prompt (you may use a DOS session under Windows):

  1. Convert the four NTAP files to the universal radar format by typing:
    	PRERADAR  NTAP1.TXT  NTAP
    	PRERADAR  NTAP2.TXT  NTAP /APPEND
    	PRERADAR  NTAP3.TXT  NTAP /APPEND
    	PRERADAR  NTAP4.TXT  NTAP /APPEND
    
  2. Convert the merged universal radar format file to Radar ViewPoint optimized file by typing:
    		MAKERADR  NTAP
    

ADVANCED INFO

Both PRERADAR and MAKERADAR have other command line options available. Execute each of the programs with the /HELP option to get a summary of the additional features. Also, the record format layout of the Universal Radar Format files (.URF) can be obtained by typing:
	MAKERADR /SHOWFORMAT
