[ncl-talk] conversion to binary

[Geeta Geeta]

Dear all. My txt data file looks like this below where column 3 and 4 are lat/lon. Each line /point corresponds to one valid data. 
I have to make 1 corresponding to the points given in the file (defined in the file) and 0 for all others (which are not defined). I request some one to help me in this. 2009-135T17:14:16.7956Z [May 15] ( 12.835,  77.396)     118496           504      11      19    65505
