Hi,
I have a large text file that has 3 numbers per line (latitude, longitude, elevation), space-delimited. Example rows are:
-75.00000 42.50000 518
-74.99583 42.50000 505
-71.40000 40.70417 -60
The first 2 numbers stay in the -75 & 42 range. I need to DELETE all lines where the 3rd value is less than -1500. I can handle string replacement OK, but I'm not sure about numbers.
Any ideas?
