I'm trying to read a csv file that's about 36000 lines long.

X,Y,TYPE,SPEED,DirType,Direction -44.058251,-19.945982,1,30,1,339 -54.629503,-20.497509,1,30,1,263 -54.646202,-20.496151,1,30,1,86

For each of the lines I want to make an operation with the coordinates and add the line to a temp file if it is within radius. I have tried some csv reading codes but none of them work properly i believe because the file is so big. How would I go about doing that?

  • split the file to as @tonygil recommend in the answer to your previous question – Juraj Jun 7 at 16:59
