How are the highlighted lines on the prof. football fields done now? Is it done digitally?

I am assuming you mean the ';1st down'; and sometimes the ';Line of Scrimmage'; lines they put on the field. IF that's the case, then it is done with special cameras and equipment, obviously if you are at a real game you cannot see them, it only appears on the tv broadcast.How are the highlighted lines on the prof. football fields done now?

Its done with computers. There is usually a Blue line to go along with the yellow first down line. Sometimes there is a red line to show where the offense needs to get to be in a field goal kickers range. But anyways they they dont use chalk or anything. They dont have someone who books it 40 across the field and gets ran over. Its all done digitally.How are the highlighted lines on the prof. football fields done now? Is it done digitally?
Yes it is done digitally, which is to say it's done using software and computers. I recall there was a certain company that invented the technology and provides it to the networks.
only the first down line that appears in yellow is done digitaly. the rest of the markings are done with simple field chalk powder, otherwise the players wouldnt see where the yard markings are.
nope, still done with good old chalk outline powder.
