Fields are pre-surveyed, and the four corners are positioned in advance. The left side of this page describes that procedure. Determining where to position the field and laying out the four outer corners is a three-person job.
Pre-Surveying: Laying out the 4 Corners
Some large fields have an adjacent baseball diamond: keep the touch line at least three feet away from the gravel, for the assistant refs.
Try to avoid bad spots in the field (overwatered, bare, irrigation control boxes) - but it's often not possible. The repainters should mark dangerous objects in the soccer fields.
For parallel fields, try to keep fields at
least 15' apart.
If the soccer field fits the area comfortably (it needs a little room
to the sides, at least 3 feet), replace the metal stakes by the
yellow plastic stakes.
Put in the yellow stake for about 1/3, then spray a solid 6" to 8" diameter dot of field paint around it (shake paint cans for about a minute before use.) Then hammer in yellow stake to near dirt level.
If the pre-survey is more than 5 days before the surveying, the paint on the dots needs to be refreshed. Take care not to paint the stake. Be sure not to leave metal stakes on the field. They may get stuck in the mowers.

Making a Corner Square
Use the 3:4:5 rule, resulting from Pythagoras theorem. From a single corner, we measure 3 units along the goal line, 4 units up the touch line, and then run a diagonal between the 3 and 4 points, and it must measure 5. Here is a table of useful 3:4:5 measurements.
