Egads, tis what I teach to my darlin' college students in Geology Lab.
1) measure yer pace...a pace be two steps, not one as in the movies.
Mark off 50 ft & count yer paces in a "normal, unforced walk". Do this 2 or three times and take the average. Then get a ft/pace unit. A 6 ft. person has about a 5-5.5 ft/pace at "normal"
walk. Pace will vary as you go uphill & downhill.
2) Shoot a transit/compass direction. Record direction. Count paces
on that transit to a particular point or landmark. Record paces...multiply by ft/pace to get footage distance. You can plot and record as you go along your area. In plotting up yer course, remember that north be at the top of the page. A protactor will be handy to have.
3) Repeat #2 for all points you desire. If you encounter an obstruction while pacing your transit line, such as a tree, rock, or massive kudzu growth, side-step at right angles from your course to clear the obstruction, continue your pacing until you clear the obstruction, and then side-step back to your original course position.
4) In walking a course, you want to end at your first point. That will give you closure in your course
5) For a good source, check out an old Boy Scout Handbook (pre-1980) under the section of "Map and Compass" or "using a Compass"
or the Boy Scout Orienteering Merit Badge Book--both can be found at your local library or at a good used book store
