How to translate tract map bearings/distances to coordinates for property corner survey using RTK GPS [closed]

Question

I have a tract map delineating property lines using distances and bearings. It looks something like this (screenshot of part of it):

My goal is to locate the exact property corners of one of these lots using an RTK GPS rental.

To do so, I believe I need WGS84 coordinates. I do already have the coordinates of one of the quarter section corners referenced in the map (in NAD83), but not of the property corners I am interested in.

How do I accurately translate the bearings and distances from the tract map to WGS84 coordinates using QGIS?

My first idea was to use the "Advanced Digitizing" tool in QGIS, to "trace" the tract map, starting from the known quarter-section coordinate. However, I'm worried that I am losing accuracy since QGIS assumes some projection, whereas the measurements I have on the map are real-world distances. For example, when I put a line 300 ft north from the starting coordinate using "advanced digitizing", I'm not sure that those 300 ft on the map correspond to the correct distance on the ground.

Any advice?

Determination of legal boundaries can only be legally done by a registered surveyor. I am not one, and neither are you, given the nature of your question. But if you want to do it for fun or so you have a rough idea (always acknowledging that your findings have no legal bearing and are probably not accurate) a general process might be:

1. Use a CAD program to draw the lot boundaries and connection to any control marks that are relevant (usually want 2-3 control marks).
2. Upload your drawing to the GPS controller.
3. Go to the site, find the control marks/monuments, and use the GPS site calibration function to adjust your boundary file to local coordinates.
4. Use the GPS to find the lot boundaries as desired.
5. Get a surveyor to do it properly before you say anything silly to your neighbours.
