I used to work for a civil engineer. One of the services he offered was property surveys, which is what I got involved in, from the field work to the plans. Here are the steps.
1. Get current deed of your property.
2. Get older deeds of your property, if available.
3. Do the same for all deeds that adjoin your property.
4. Make sure your deed description 'closes'
5. Compare all the deeds to make sure the directions and distances match.
6. If they don't, figure out why and try to determine which directions and distances are correct.
7. Perform field work to find existing markers and place new ones.
Typically, deeds begin with a phrase "Starting at a point...." We'd try and find this point first. Sometimes it's measuring from landmarks, other property lines, etc. These days it might mean using a GPS to find the point. If the starting point can not be found, we have to measure from a known point then traverse to get to the property being surveyed. Also, if one of your property line(s) is a road, the line probably runs down the center of the road. (This is true in PA, perhaps not where you live).
Can you do this yourself? Yep. All the documents I mentioned above are available at the county courthouse at the Recorder of Deeds office.
You didn't state why you want to do this, which would be helpful in answering if it's wise to do this yourself.
